Table des matières

13.1. Hardware Information
13.2. Setting Up Sound Cards
13.3. Setting Up a Scanner

YaST allows you to configure hardware items at installation time as well as on an already-installed system. Configure audio hardware, printers or scanner support or learn which hardware components are connected to your computer by using the YaST Hardware Information module.

[Tip]Graphics card, monitor, mouse and keyboard settings

Graphics card, monitor, mouse and keyboard can be configured with either KDE or GNOME tools.

13.1. Hardware Information

Use the YaST hardware information module if you want to know more about your hardware or if you need to find out details like vendor and model of a certain piece of hardware to be able to properly configure it.

  1. Start YaST and click Hardware+Hardware Information. Hardware probing starts immediately and it will take some time until you see the hardware information tree in a separate window.

  2. In the hardware information tree recursively click on the entries to expand the information about a specific device.

  3. Click Save to File... to save the output to a file.

  4. Click Close to leave the hardware information overview.

13.2. Setting Up Sound Cards

YaST detects most sound cards automatically and configures them with the appropriate values. If you want to change the default settings, or need to set up a sound card that could not be configured automatically, use the YaST sound module. There, you can also set up additional sound cards or switch their order.

To start the sound module, start YaST and click Hardware+Sound. Alternatively, start the Sound Configuration dialog directly by running yast2 sound & as user root from a command line.

The dialog shows all sound cards that could be detected.

Procédure 13.1. Configuring Sound Cards

If you have added a new sound card or YaST could not automatically configure an existing sound card, follow the steps below. For configuring a new sound card, you need to know your sound card vendor and model. If in doubt, refer to your sound card documentation for the required information. For a reference list of sound cards supported by ALSA with their corresponding sound modules, see http://www.alsa-project.org/main/index.php/Matrix:Main.

During configuration, you can choose between the following setup options:

Quick Automatic Setup

You are not required to go through any of the further configuration steps—the sound card is configured automatically. You can set the volume or any options you want to change later.

Normal Setup

Allows you to adjust the output volume and play a test sound during the configuration.

Advanced setup with possibility to change options

For experts only. Allows you to customize all parameters of the sound card.

[Important]Advanced Configuration

Only use this option if you know exactly what your are doing. Otherwise leave the parameters untouched and use the normal or the automatic setup options.

  1. Start the YaST sound module.

  2. To configure a detected, but Not Configured sound card, select the respective entry from the list and click Edit.

    To configure a new sound card, click Add. Select your sound card vendor and model and click Next.

  3. Choose one of the setup options and click Next.

  4. If you have chosen Normal Setup, you can now Test your sound configuration and make adjustments to the volume. You should start at about ten percent volume to avoid damage to your hearing or the speakers.

  5. If all options are set according to your wishes, click Next.

    The Sound Configuration dialog shows the newly configured or modified sound card.

  6. To remove a sound card configuration that you no longer need, select the respective entry and click Delete.

  7. Click OK to save the changes and leave the YaST sound module.

Procédure 13.2. Modifying Sound Card Configurations

  1. To change the configuration of an individual sound card (for experts only!), select the sound card entry in the Sound Configuration dialog and click Edit.

    This takes you to the Sound Card Advanced Options where you can fine-tune a number of parameters. For more information, click Help.

  2. To adjust the volume of an already configured sound card or to test the sound card, select the sound card entry in the Sound Configuration dialog and click Other. Select the respective menu item.

    [Note]YaST Mixer

    The YaST mixer settings provide only basic options. They are intended for troubleshooting (for example, if the test sound is not audible). Access the YaST mixer settings from Other+Volume. For everyday use and fine-tuning of sound options, use the mixer applet provided by your desktop or the alsasound command line tool.

  3. For playback of MIDI files, select Other+Start Sequencer.

  4. When a supported sound card is detected (like a Creative Soundblaster Live, Audigy or AWE sound card), you can also install SoundFonts for playback of MIDI files:

    1. Insert the original driver CD-ROM into your CD or DVD drive.

    2. Select Other+Install SoundFonts to copy SF2 SoundFonts™ to your hard disk. The SoundFonts are saved in the directory /usr/share/sfbank/creative/.

  5. If you have configured more than one sound card in your system you can adjust the order of your sound cards. To set a sound card as primary device, select the sound card in the Sound Configuration and click Other+Set as the Primary Card. The sound device with index 0 is the default device and thus used by the system and the applications.

  6. Per default, openSUSE uses the PulseAudio sound system. It is an abstraction layer that helps to mix multiple audio streams, bypassing any restrictions the hardware may have. To enable or disable the PulseAudio sound system, click Other+PulseAudio Configuration. If enabled, PulseAudio daemon is used to play sounds. Disable PulseAudio Support in case you want to use something else system-wide.

The volume and configuration of all sound cards are saved when you click OK and leave the YaST sound module. The mixer settings are saved to the file /etc/asound.state. The ALSA configuration data is appended to the end of the file /etc/modprobe.d/sound and written to /etc/sysconfig/sound.

13.3. Setting Up a Scanner

You can configure a USB or SCSI scanner with YaST. The sane-backends package contains hardware drivers and other essentials needed to use a scanner. Scanners connected to a parallel port cannot be configured with YaST. If you own a HP All-In-One device, see Section 13.3.1, « Configuring an HP All-In-One Device », instructions on how to configure a network scanner are available at Section 13.3.3, « Scanning over the Network ».

Procédure 13.3. Configuring a USB or SCSI Scanner

  1. Connect your USB or SCSI scanner to your computer and turn it on.

  2. Start YaST and select Hardware+Scanner. YaST builds the scanner database and tries to detect your scanner model automatically.

    If a USB or SCSI scanner is not properly detected, try Other+Restart Detection.

  3. To activate the scanner select it from the list of detected scanners and click Edit.

  4. Choose your model form the list and click Next and Finish.

  5. Use Other+Test to make sure you have chosen the correct driver.

  6. Leave the configuration screen with OK.

13.3.1. Configuring an HP All-In-One Device

An HP All-In-One device can be configured with YaST even if it is connected to the parallel port or is made available via the network. If you own a USB HP All-In-One device, start configuring as described in Procédure 13.3, « Configuring a USB or SCSI Scanner ». If it is detected properly and the Test succeeds, it is ready to use.

If your USB device is not properly detected, or your HP All-In-One device is connected to the parallel port or the network, run the HP Device Manager:

  1. Start YaST and select Hardware+Scanner. YaST loads the scanner database.

  2. Start the HP Device Manager with Other+Run hp-setup and follow the on-screen instructions. After having finished the HP Device Manager, the YaST scanner module automatically restarts the auto detection.

  3. Test it by choosing Other+Test.

  4. Leave the configuration screen with OK.

13.3.2. Sharing a Scanner over the Network

openSUSE allows the sharing of a scanner over the network. To do so, configure your scanner as follows:

  1. Configure the scanner as described in Section 13.3, « Setting Up a Scanner ».

  2. Choose Other+Scanning via Network.

  3. Enter the hostnames of the clients (separated by a comma) that should be allowed to use the scanner under Server Settings+Permitted Clients for saned and leave the configuration dialog with OK.

13.3.3. Scanning over the Network

To use a scanner that is shared over the network, proceed as follows:

  1. Start YaST and select Hardware+Scanner.

  2. Open the network scanner configuration menu by Other+Scanning via Network.

  3. Enter the hostname of the machine the scanner is connected to under Client Settings+Servers Used for the net Metadriver

  4. Leave with OK. The network scanner is now listed in the Scanner Configuration window and is ready to use.
