2.4. Hardware

New hardware must first be installed or connected as specified by the vendor. Turn on external devices, such as the printer or the modem, and start the respective YaST module. Most devices are automatically detected by YaST and the technical data is displayed. If the automatic detection fails, YaST offers a list of devices (model, vendor, etc.) from which to select the suitable device. Consult the documentation enclosed with your hardware for more information.

[Important]Model Designations

If your model is not included in the device list, try a model with a similar designation. However, in some cases the model must match exactly, as similar designations do not always indicate compatibility.

2.4.1. CD-ROM and DVD Drives

Within the scope of the installation, all detected CD-ROM drives are integrated in the installed system by means of entries in the file /etc/fstab. The respective subdirectories are created in /media. Use this YaST module to integrate additional drives in the system.

When the module is started, a list of all detected drives is displayed. Mark your new drive using the check box at the beginning of the line and complete the integration with Finish. The new drive is then integrated in the system.

2.4.2. Printer

A Linux system manages printers through print queues. Before any data is printed, it is sent to a print queue for temporary storage. From there, it is retrieved by a print spooler, which sends it to the printer device in the required order.

Usually, this data is not available in a form that can be processed by the printer. A graphical image, for instance, first needs to be converted into a format the printer can understand. This conversion to a printer language is achieved with a print filter.

2.4.2.1. Some Standard Printer Languages

Standard printer languages can be categorized in the following three groups:

ASCII Text

Every normal printer can print ASCII text directly. However, there are printers that cannot print ASCII text directly, but can be addressed by means of one of the following standard printer languages.

PostScript

PostScript is the established printer language on Unix and Linux systems. However, PostScript data can be printed directly only by PostScript printers.

PCL3, PCL4, PCL5e, PCL6, ESC/P, ESC/P2, and ESC/P Raster

If a PostScript printer is not available, the print filter can use Ghostscript to convert PostScript data into one of these other standard printer languages. Ghostscript relies on different drivers for different printers to make the best possible use of specific features offered by the various models (such as color settings).

2.4.2.2. How a Print Job is Processed

  1. The user or an application generates a new print job.

  2. The print data is temporarily stored in the print queue. The print spooler sends it from there to the printer filter.

  3. Now the printer filter performs the following steps:

    1. It determines the type of print data.

    2. The print data is converted into PostScript, if not in PostScript already.

    3. If necessary, the PostScript data is converted to another printer language.

      • If the printer is a PostScript model, the PostScript data is sent directly to the printer.

      • If the printer is not a PostScript model, Ghostscript uses a driver suitable for the respective printer to generate the printer-specific data that is subsequently sent to the printer.

  4. After the entire job has been sent to the printer, the print spooler removes the job from the queue.

2.4.2.3. Supported Printers

Because most Linux printer drivers are not written by the manufacturer of the hardware, it is crucial that the printer can be driven through one of the generally known languages. Normal printers understand at least one of these common languages. In the case of a GDI printer, however, the manufacturer has built a device that relies on its own special control sequences. Many inexpensive ink jet models belong to this group. Such a printer only runs out of the box under the versions of the operating systems for which the manufacturer has included a driver. Because the device cannot be operated through one of the standard languages, it cannot be used with Linux or can only be used with difficulties.

Nevertheless, some of these printers are supported by SUSE LINUX. However, their use is often rather problematic and some features might not be available at all. For example, the printer could be limited to low resolution monochrome printing. Refer to Proprietary Printers (usually GDI printers) and 12.6.1. “Printers without Standard Printer Language Support” for more information about the use of these devices.

2.4.2.4. Configuration with YaST

To configure the printer, select Hardware+Printer in the YaST control center. This opens the main printer configuration window, where the detected devices are listed in the upper part. The lower part lists any queues configured so far. If your printer was not detected, configure it manually.

2.4.2.5. Automatic Configuration

YaST is able to configure the printer automatically if the parallel or USB port can be set up automatically and the connected printer can be detected. The printer database must also contain the ID string of the printer that YaST retrieves during the automatic hardware detection. If the hardware ID differs from the model designation, select the model manually.

To make sure everything works properly, each configuration should be checked with the print test function of YaST. The YaST test page also provides important information about the configuration that is being tested.

2.4.2.6. Manual Configuration

If the requirements for automatic configuration are not met or if you want a custom setup, configure the printer manually. Depending on how successful the autodetection is and how much information about the printer model is found in the database, YaST may be able to determine the right settings automatically or at least make a reasonable preselection.

The following parameters must be configured:

Hardware Connection (Port)

The configuration of the hardware connection depends on whether YaST has been able to find the printer during hardware autodetection. If YaST is able to detect the printer model automatically, it can be assumed that the printer connection works on the hardware level and no settings need to be changed in this respect. If YaST is unable to autodetect the printer model, there may be some problem with the connection on the hardware level. In this case, some manual intervention is required to configure the connection.

Name of the Queue

The queue name is used when issuing print commands. The name should be relatively short and consist of lowercase letters and numbers only.

Printer Model and PPD File

All printer-specific parameters, such as the Ghostscript driver to use and the printer filter parameters for the driver, are stored in a PPD (PostScript Printer Description) file. See 12.3. “Installing the Software” for more information about PPD files.

For many printer models, several PPD files are available, for example, if several Ghostscript drivers work with the given model. When you select a manufacturer and a model, YaST selects the PPD file that corresponds to the printer. If several PPD files are available for the model, YaST defaults to one of them (normally the one marked recommended). You can change the default PPD file after selecting Edit.

For non-PostScript models, all printer-specific data is produced by the Ghostscript driver. For this reason, the driver configuration is the single most important factor determining the output quality. The printout is affected both by the kind of Ghostscript driver (PPD file) selected and the options specified for it. If necessary, change additional options (as made available by the PPD file) after selecting Edit.

Figure 2.6. Selecting the Printer Model

Selecting the Printer Model

Always check whether your settings work as expected by printing the test page. If the output is garbled, for example, with several pages almost empty, you should be able to stop the printer by first removing all paper then stopping the test from YaST.

If the printer database does not include an entry for your model, you can use a collection of generic PPD files to make the printer work with one of the standard printer languages. To do so, select UNKNOWN MANUFACTURER as your printer manufacturer.

Advanced Settings

Normally, you do not need to change any of these settings.

2.4.2.7. Configuration for Applications

Applications rely on the existing printer queues in the same way as any command-line tools do. There is usually no need to reconfigure the printer for a particular application, because you should be able to print from applications using the available queues.

Printing from the Command Line

To print from the command line, enter the command lp -d queuename filename, substituting the corresponding names for queuename and filename.

Printing from Applications Using the Command-Line Tool

Some applications rely on the above-mentioned lp command for printing. In this case, enter the correct command in the application's print dialog (but usually without specifying filename), for example, lp -d queuename. To make this work with KDE programs, enable Print through an external program. Otherwise you cannot enter the print command.

Using the CUPS Printing System

Tools such as xpp and the KDE program kprinter provide a graphical interface to choose among queues and to set both CUPS standard options and printer-specific options as made available through the PPD file. You can use kprinter as the standard printing interface of other (non-KDE) applications by specifying kprinter or kprinter --stdin as the print command in the print dialogs of these applications. The behavior of the application itself determines which of these two commands to choose. If set up correctly, the application should call the kprinter dialog whenever a print job is issued from it, so you can use the dialog to select a queue and to set other printing options. This requires that the application's own print setup does not conflict with that of kprinter and that printing options are only changed through kprinter after it has been enabled.

2.4.2.8. Troubleshooting

If there is some kind of error in the communication between the computer and the printer, the printer may no longer be able to interpret data in the correct way. This could cause the output to be garbled and use up large amounts of paper. To correct this, follow the instructions in 12.6.8. “Defective Print Jobs and Data Transfer Errors”.

2.4.2.9. For More Information

Detailed information about printing in Linux is available in 12. Printer Operation, which covers general printing issues. Solutions to many specific problems are presented in the Support Database. If you experience problems with printers, refer to the Support Database articles Installing a Printer and Printer Configuration from SUSE LINUX 9.2, which you can find by searching for the keyword “printer”.

2.4.3. Hard Disk Controller

Normally YaST configures the hard disk controller of your system during the installation. If you add controllers, integrate these into the system with this YaST module. You can also modify the existing configuration, but this is generally not necessary.

The dialog presents a list of detected hard disk controllers and enables assignment of the suitable kernel module with specific parameters. Use Test Loading of Module to check if the current settings work before they are saved permanently in the system.

[Warning]Configuration of the Hard Disk Controller

This is an expert tool. Your system may no longer boot if you make incorrect settings. If you make changes, use the test option.

2.4.4. Graphics Card and Monitor (SaX2)

The graphical user interface, or X server, handles the communication between hardware and software. Desktops, like KDE and GNOME, and the wide variety of window managers use the X server for interaction with the user.

The graphical user interface is initially configured during installation. To change the settings afterwards, run this YaST module. In the configuration dialog, choose between Text Mode Only and the graphical user interface. The current settings are saved and you can reset to them at any time. The current values are displayed and offered for modification: the screen resolution, the color depth, the refresh rate, and the vendor and type of your monitor, if autodetected.

If you have just installed a new graphics card, a small dialog appears asking whether to activate 3D acceleration for your graphics card. Click Edit. SaX2, the configuration tool for the input and display devices, starts in a separate window. This window is shown in Figure 2.7. “The Main Window of SaX2”.

Figure 2.7. The Main Window of SaX2

The Main Window of SaX2

In the left navigation bar, there are four main items: Display, Input devices, Multihead, and AccessX. Configure your monitor, graphics card, color depth, resolution, and the position and size of the screen under Display. The keyboard, mouse, touchscreen monitor, and graphics tablet can be configured under Input devices. Use Multihead to configure multiple screens (see 2.4.4.7. “Multihead”). AccessX is a useful tool for controlling the mouse pointer with the number pad.

Select your monitor and graphics card. Usually, the monitor and graphics card are autodetected by the system. If your monitor is not autodetected, automatically proceed to the monitor selection dialog. Select your monitor from the extensive list of vendors and devices or manually enter the monitor values specified in the monitor manual. Alternatively, select one of the preconfigured VESA modes.

Click Finish in the main window following the completion of the settings for your monitor and your graphics card then test your settings. This ensures that your configuration is suitable for your devices. If the image is not steady, terminate the test immediately by pressing Esc and reduce the refresh rate or the resolution and color depth. Regardless of whether you run a test, all modifications are only activated when you restart the X server.

2.4.4.1. Display

With Edit configuration+Properties, a window with the tabs Monitor, Frequencies, and Expert appears.

Monitor

In the left part of the window, select the vendor. In the right part, select your model. If you have floppy disks with Linux drivers for your monitor, install these by clicking Manufacturer Disk.

Figure 2.8. Monitor Selection

Monitor Selection
Frequencies

Here, enter the horizontal and vertical frequencies for your screen. The vertical frequency is another designation for the image refresh rate. Normally, the acceptable value ranges are read from the model and entered here. Usually, they do not need to be changed.

Expert

Here, enter some options for your screen. In the upper selection field, define the method to use for the calculation of the screen resolution and screen geometry. Do not change anything unless the monitor is addressed incorrectly and the display is not stable. Additionally, you can change the size of the displayed image and activate the power saving mode DPMS.

[Warning]Configuring the Monitor Frequencies

There are safety mechanisms, but you should still be very careful when manually changing the allowed frequencies. Incorrect values may destroy your monitor. If in doubt, refer to the manual of the monitor.

2.4.4.2. Graphics Card

The graphics card dialog has two tabs: General and Expert. In General, select the vendor of your graphics card on the left side and the model on the right.

Figure 2.9. Selecting the Graphics Card

Selecting the Graphics Card

Expert offers more advanced configuration possibilities. On the right side, turn your screen to the left or to a vertical position (useful for some turnable TFT screens). The entries for the BusID are only relevant if you operate several screens. Normally, nothing needs to be changed here. You should not modify the card options unless you have experience in this field and know what the options mean. If necessary, check the documentation of your graphics card.

2.4.4.3. Colors and Resolutions

Here, three tabs, Colors, Resolution, and Expert, are available.

Colors

Depending on the hardware used, select a color depth of 16, 256, 32768, 65536, or 16.7 million colors (4, 8, 15, 16, or 24 bit). For a reasonable display quality, set at least 256 colors.

Resolution

The module offers all resolution and color depth combinations that your hardware can display correctly. This keeps the danger of damaging your hardware with incorrect settings very low in SUSE LINUX. If you change the resolution manually, consult the documentation of your hardware to make sure the value set can be displayed.

Figure 2.10. Configuring the Resolution

Configuring the Resolution
Expert

In addition to the resolutions offered in the previous tab, this tab enables you to add your own resolutions, which will subsequently be included for selection in the tab.

2.4.4.4. Virtual Resolution

Every desktop has a certain resolution that is displayed over the full screen of the monitor. Additionally, it is possible to set the resolution larger than the visible area of the screen. If you move the mouse beyond the margins of the desktop, the virtual part of the desktop is displayed on screen. This increases the available work space.

Figure 2.11. Configuring the Virtual Resolution

Configuring the Virtual Resolution

The virtual resolution can be set in two different ways. To set it using By Drag&Drop, move the mouse pointer over the monitor image so it turns into crosshairs. Keep the left mouse button pressed and move the mouse to enlarge the raster image, which corresponds with the virtual resolution. This method is best if you are not quite sure how much virtual space you want on your desktop.

For By selection from the pop-up menu, the pop-up menu in the middle of the raster image displays the currently used virtual resolution. To use one of the default virtual resolutions, select one from the menu.

2.4.4.5. 3D Acceleration

If you did not activate 3D acceleration during the initial installation or when you installed a new graphics card, you can do this here.

2.4.4.6. Image Position and Size

Under these two tabs, precisely adjust the size and the position of the image with the arrows. See Figure 2.12. “Adjusting the Image Geometry”. If you have a multihead environment (more than one screen), use Next screen to switch to the other monitors to adjust their sizes and positions. Press Save to save your settings.

Figure 2.12. Adjusting the Image Geometry

Adjusting the Image Geometry

2.4.4.7. Multihead

If you have installed more than one graphics card in your computer or a graphics card with multiple outputs, you can connect more than one screen to your system. If you operate two screens, this is referred to as dualhead. More than two is referred to as multihead. SaX2 automatically detects multiple graphics cards in the system and prepares the configuration accordingly. Set the multihead mode and the arrangement of the screens in the multihead dialog. Three modes are offered: Traditional (default), One screen (Xinerama), and Clone mode.

Traditional Multihead

Each monitor represents an individual unit. The mouse pointer can switch between the screens.

Cloned Multihead

In this mode, all monitors display the same contents. The mouse is only visible on the main screen.

Xinerama Multihead

All screens combine to form a single large screen. Program windows can be positioned freely on all screens or scaled to a size that fills more than one monitor.

The layout of a multihead environment describes the arrangement of and the relationship between the individual screens. By default, SaX2 configures a standard layout that follows the sequence of the detected graphics cards, arranging all screens in a row from left to right. In the Layout dialog of the multihead tool, determine the way the monitors are arranged by using the mouse to move the screen symbols in the grid. After completing the layout dialog, verify the new configuration by clicking Test.

Linux currently does not offer 3D support for Xinerama multihead environments. In this case, SaX2 deactivates the 3D support.

2.4.4.8. Input Devices

Mouse

If the automatic detection fails, use this dialog to configure your mouse manually. Refer to the documentation of your mouse for a description of the model. Select your model from the list of supported mouse types and confirm by pressing 5 on the number pad.

Keyboard

Use the selection field at the top of this dialog to specify the kind of keyboard to use. Then select the language for the keyboard layout (the country-specific position of the keys). Use the test field to check if special characters are displayed correctly.

The status of the check box used for activating and deactivating the entry of accented letters depends on the respective language and does not need to be changed. Click Finish to apply the new settings to your system.

Touchscreen

Currently, X.Org only supports Microtouch and Elo TouchSystems touchscreens. SaX2 can only autodetect the monitor, not the toucher. The toucher is treated as an input device.

To configure the toucher, start SaX2 and select Input devices+Touchscreens. Click Add and add a touchscreen. Save the configuration by clicking Finish. You do not need to test the configuration.

Touchscreens feature a variety of options and usually must be calibrated first. Unfortunately, there is no general tool for this purpose in Linux. The standard configuration contains suitable default values for the dimensions of the touchscreen. Normally, no additional configuration is required.

Graphics Tablet

Currently, X.Org only supports a limited number of graphics tablets. SaX2 enables the configuration of graphics tablets connected to the USB port or the serial port. From the configuration perspective, a graphics tablet is just an input device like a mouse.

Start SaX2 and select Input devices+Graphics tablet. Click Add, select the vendor from the following dialog, and add a graphics tablet from the selection list. Mark the check boxes to the right if you have connected a pen or eraser. If your tablet is connected to the serial port, verify the port. /dev/ttyS0 refers to the first serial port. /dev/ttyS1 refers to the second. Additional ports use similar notation. Save the configuration by clicking Finish.

2.4.4.9. AccessX

If you do not use a mouse on your computer, start SaX2 and activate AccessX to be able to control the mouse pointer with the keys on the numeric keypad. See Table 2.1. “AccessX — Operating the Mouse with the Numeric Keypad” for a description of the functions of the different keys. Use the slider to set the speed of the mouse pointer movement when a key is pressed.

2.4.4.10. For More Information

For more information about the X Window System and its properties, refer to 11. The X Window System.

2.4.5. Hardware Information

YaST detects hardware for the configuration of hardware components. The detected technical data is displayed in a separate screen. This is especially useful, for example, if you want to submit a support request for which you need information about your hardware.

Figure 2.13. Displaying Hardware Information

Displaying Hardware Information

2.4.6. IDE DMA Mode

With this module, activate and deactivate the DMA mode for your IDE hard disks and your IDE CD and DVD drives in the installed system. This module does not have any effect on SCSI devices. DMA modes can substantially increase the performance and data transfer speed in your system.

During the installation, the current SUSE LINUX kernel automatically activates DMA for hard disks but not for CD drives, because default DMA activation for all drives often caused problems with CD drives. Use the DMA module to activate DMA for your drives. If the drive supports the DMA mode without any problems, the data transfer rate of your drive can be increased by activating DMA.

[Important]Important

DMA (direct memory access) means that your data can be transferred directly to the RAM, bypassing the processor control.

2.4.7. Joystick

Use this module to configure your joystick by selecting the manufacturer and the model from the displayed list. With Test, check if your joystick responds correctly. The test dialog shows three charts for the analog axes of the joystick and marks for the four standard buttons. When you move the joystick or press the buttons, you should be able to see a reaction in the test dialog. Because joysticks are usually connected to the sound card, you can also access this module from the sound card configuration.

2.4.8. Keyboard Layout Selection

The desired keyboard layout usually matches the selected language, but can also be selected regardless of the language. Use the test field to see if special characters such as the pipe symbol | are displayed correctly.

2.4.9. Mouse

Configure your mouse with this YaST module. The procedure for the selection of the mouse was already explained for installation, so refer to 1.5.3. “Mouse”.

2.4.10. Scanner

If your scanner is connected and switched on, it should be detected automatically when this YaST module is started. In this case, the dialog for the installation of the scanner appears. If no scanner is detected, the manual configuration dialog appears. If you have already installed one or several scanners, a list of existing scanners that can be modified or deleted is displayed. Press Add to configure a new device.

Next, an installation is performed with default settings. If the installation is successful, a corresponding message appears. Now, test your scanner by inserting a document and clicking Test.

2.4.10.1. Scanner Not Detected

Only supported scanners can be autodetected. Scanners connected to another network host cannot be detected. The manual configuration distinguishes three types of scanners: USB scanners, SCSI scanners, and network scanners.

USB Scanner

Specify the vendor and model. YaST then attempts to load USB modules. If your scanner is very new, the modules may not be loaded automatically. In this case, continue automatically to a dialog in which to load the USB module manually. Refer to the YaST help text for more information.

SCSI Scanner

Specify the device, such as /dev/sg0. SCSI scanners should not be connected or disconnected when the the system is running. Shut the system down first.

Network Scanner

Enter the IP address or the host name. To configure a network scanner, refer to the Support Database article Scanning in Linux (http://sdb.suse.de/en/, keyword scanner).

If your scanner was not detected, the device probably is not supported. However, sometimes even supported scanners are not detected. If that is the case, proceed with the manual scanner selection. If you can identify your scanner in the list of vendors and models, select it. If not, select Cancel. Information about scanners that work with Linux is provided at http://cdb.suse.de/index.php?LANG=en and http://www.mostang.com/sane.

[Warning]Assigning a Scanner Manually

Only assign the scanner manually if you are absolutely sure. Incorrect selection could damage your hardware.

2.4.10.2. Troubleshooting

Your scanner may not have been detected for one of the following reasons:

  • The scanner is not supported. Check http://cdb.suse.de/index.php?LANG=en for a list of Linux-compatible devices.

  • The SCSI controller was not installed correctly.

  • There are termination problems with your SCSI port.

  • The SCSI cable is too long.

  • The scanner has a SCSI light controller that is not supported by Linux.

  • The scanner is defective.

[Warning]Warning

SCSI scanners should not be connected or disconnected when the the system is running. Shut the system down first.

For more information about scanning, refer to the chapter about kooka in the User Guide.

2.4.11. Sound

When the sound configuration tool is started, YaST tries to detect your sound card automatically. Configure one or multiple sound cards. To use multiple sound cards, start by selecting one of the cards to configure. Press Configure to enter the Setup dialog. Edit opens a dialog in which to edit previously configured sound cards. Finish saves the current settings and completes the sound configuration.

If YaST is unable to detect your sound card automatically, press Add Sound Card in Sound Configuration to open a dialog in which to select a sound card and module. Refer to your sound card documentation for the information required. A reference list of sound cards supported by ALSA with their corresponding sound modules is available in /usr/share/doc/packages/alsa/cards.txt and at http://www.alsa-project.org/~goemon/. After making your selection, click Next to return to Setup.

2.4.11.1. Setup

Choose the configuration level in the first setup screen. With Quick Automatic Setup, you are not required to go through any of the further configuration steps and no sound test is performed. The sound card is configured automatically. With Normal Setup, you have the possibility to adjust the output volume and play a test sound. Advanced Setup allows you to customize the sound card options manually.

In this dialog, also find a shortcut to the joystick configuration. Click the respective check box. Select the joystick type in the following dialog and click Next.

2.4.11.2. Sound Card Volume

Test your sound configuration in this test screen. Use + and to adjust the volume. Start at about ten percent to avoid damage to your speakers or hearing. A test sound should be audible when you press Test. If you cannot hear anything, increase the volume. Press Continue to complete the sound configuration. The volume setting is then saved.

2.4.11.3. Sound Configuration

Use Delete to remove a sound card. Existing entries of configured sound cards are deactivated in the file /etc/modprobe.d/sound. Click Options to open a dialog in which to customize the sound module options manually. Under Add Sound Card..., configure additional sound cards. If YaST detects another sound card, continue to Configure a Sound Card. If YaST does not detect a sound card, automatically be directed to Manual Sound Card Selection.

If you use a Creative Soundblaster Live or AWE sound card, copy SF2 sound fonts to your hard disk from the original Soundblaster driver CD-ROM with Install Sound Fonts. The sound fonts are saved in the directory /usr/share/sfbank/creative/.

For playback of MIDI files, activate Start Sequencer. This way, the modules for sequencer support are loaded along with the sound modules.

The volume and configuration of all sound cards installed are saved when you click Finish. The mixer settings are saved to the file /etc/asound.conf and the ALSA configuration data is appended at the end of the file /etc/modprobe.conf.

2.4.12. TV and Radio Cards

After starting and initializing this YaST module, the TV and Radio Cards dialog appears. If your card was automatically detected, it is displayed at the top of the list. In this case, highlight the line with the mouse and select Configure. If your card was not detected, select Other (not recognized). Press Configure to proceed with the manual selection in which to select your card from the list of vendors and models.

If you have already configured TV or radio cards, modify existing configurations with Change. In this case, a dialog presents a list of all configured cards. Select a card and start the manual configuration with Edit.

During the automatic hardware detection, YaST attempts to assign the correct tuner to your card. If you are not sure, simply keep the setting Default (recognized) and check whether it works. If you are not able to set all channels, this might be due to a failure of the automatic detection of the tuner type. In this case, click Select Tuner and highlight the correct tuner type in the list.

If you are familiar with the technical details, you can use the expert dialog to specify settings for a TV or radio card. Select a kernel module and its parameters in this dialog. Also check all parameters of your TV card driver. To do this, select the respective parameters and enter the new value in the parameter line. Confirm the new values with Apply or restore the default values with Reset.

The dialog TV and Radio Cards, Audio enables you to connect your TV or radio card with the installed sound card. You must use a cable to connect the output of the TV or radio card with the external audio input of the sound card. This only works if the sound card is already configured and the external input is active. If you have not yet configured your sound card, select Configure Sound Card to go to the respective dialog, described in 2.4.11. “Sound”.

If your TV or radio card has speaker jacks, you can also connect the speakers directly without configuring the sound card. There are also TV cards without any sound function, which do not require an audio configuration, such as those for CCD cameras.


SUSE LINUX 9.2
