2.4. Hardware

New hardware must first be installed or connected as directed by the vendor. Turn on external devices, such as the printer or the modem, and start the appropriate 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, because similar designations do not always indicate compatibility.

2.4.1. Bluetooth

Configure Bluetooth devices with Hardware+Bluetooth. Click Enable Bluetooth Services to begin configuration. Bluetooth configuration is covered in detail in Section 34.2.2.1, “Configuring Bluetooth with YaST” (↑Reference).

2.4.2. Infrared Device

Configure an infrared device with Hardware+Infrared Device. Click Start IrDa to begin configuration. You can configure Port and Limit Baud Rate here. Find information about infrared devices in Section 34.3, “Infrared Data Transmission” (↑Reference).

2.4.3. Graphics Card and Monitor

Configure graphics cards and monitors with Hardware+Graphics Card and Monitor. It uses the the SaX2 interface, described in Section 2.13, “SaX2”.

2.4.4. Printer

Configure a printer with Hardware+Printer. If a printer is properly connected to the system, it should be detected automatically. Find detailed instructions for configuring printers with YaST in Section 11.4, “Configuring the Printer” (↑Reference).

2.4.5. Hard Disk Controller

Normally, the hard disk controller of your system is configured during the installation. If you add controllers, integrate these into the system with Hardware+Disk Controller. 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.

2.4.6. Hardware Information

Display detected hardware and technical data using Hardware+Hardware Information. Click any node of the tree for more information about a device. This module is especially useful, for example, when submitting a support request for which you need information about your hardware.

Save the hardware information displayed to a file by clicking Save to File. Select the desired directory and filename then click Save to create the file.

2.4.7. IDE DMA Mode

Activate and deactivate the DMA mode for your IDE hard disks and your IDE CD and DVD drives in the installed system with Hardware+IDE DMA Mode. 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 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 causes 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.

[Note]Note

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

2.4.8. Joystick

Configure a joystick connected to the sound card with Hardware+Joystick. Select your joystick type in the list provided. If your joystick is not listed, select Generic Analog Joystick. After selecting your joystick, make sure that it is connected then click Test to test the functionality. Click Continue and YaST installs the required files. After the Joystick Test window appears, test the joystick by moving it in all directions and pressing all buttons. Each movement should be displayed in the window. If you are satisfied with the settings, click OK to return to the module and Finish to complete configuration.

If you have a USB device, this configuration is not necessary. Plug in the joystick and start using it.

2.4.9. Keyboard Layout

To configure the keyboard for the console, run YaST in text mode then use Hardware+Keyboard Layout. After clicking the module, the current layout is displayed. To choose another keyboard layout, select the desired layout from the list provided. Test the layout in Test by pressing keys on the keyboard.

Fine-tune the settings by clicking Expert Settings. You can adjust the key repeat rate and delay and configure the start-up state by choosing the desired settings in Start-Up States. For Devices to Lock, enter a space-separated list of devices to which to apply the Scroll Lock, Num Lock, and Caps Lock settings. Click OK to complete the fine-tuning. Finally, after all selections have been made, click Accept for your changes to take effect.

To set up the keyboard for the graphical environment, run the graphical YaST then select Keyboard Layout. Find information about the graphical configuration in Section 2.13.3, “Keyboard Properties”.

2.4.10. Mouse Model

When configuring the mouse for the graphical environment, click Mouse Model to access the SaX2 mouse configuration. Refer to Section 2.13.2, “Mouse Properties” for details.

To configure your mouse for the text environment, use YaST in text mode. After entering text mode and selecting Hardware+Mouse Model, use the keyboard arrow keys to choose your mouse from the provided list. Then click Accept to save the settings and exit the module.

2.4.11. Scanner

Connect and turn on your scanner then select Hardware+Scanner to configure it. Most supported scanners are detected automatically. Select the scanner to configure and click Edit. If your scanner is not listed, click Add to open the manual configuration dialog. Select the appropriate vendor and model from the list and click Next to proceed with the installation. To modify a configured scanner, select it then click Edit.

After the scanner has been determined by either automatic detection or user selection, installation is carried out. Click Finish to complete the installation. If the installation is successful, a corresponding message appears. To test your scanner after installation, insert a document into your scanner and click Other+Test.

2.4.11.1. Scanner Not Detected

Only supported scanners can be detected automatically. 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

After the scanner is selected, YaST attempts to load the 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

SCSI devices are normally detected. Specify the device, such as /dev/sg0. If problems arise, refer to the YaST help text. Remember always to shut down the system before connecting or disconnecting a SCSI scanner.

Network Scanner

Enter the IP address or the hostname. To configure a network scanner, refer to the database article Scanning in Linux (http://en.opensuse.org/SDB:SDB).

If your scanner is not detected, the device is probably not supported. However, sometimes even supported scanners are not detected. If this 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/ and http://www.sane-project.org/.

[Warning]Assigning a Scanner Manually

Assign the scanner manually only if you are absolutely sure. An incorrect selection could damage your hardware.

2.4.11.2. Troubleshooting

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

  • The scanner is not supported. Check http://cdb.suse.de/ for a list of Linux-compatible devices.

  • The SCSI controller was not installed correctly.

  • There were 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 while the system is running. Shut the system down first.

2.4.12. TV and Radio Cards

Configure TV and radio cards with Hardware+TV Card. If your card was automatically detected, it is displayed in the list. In this case, select the card and click Edit. If your card was not detected, click Add. If you have already configured TV or radio cards, select a card to modify then click 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 cannot set all channels, click Select Tuner and select the correct tuner type from the list.

If you are familiar with the technical details, you can use the expert dialog to make 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.

Configure audio settings if your TV or radio card is connected to the installed sound card. Make the connection with a cable from output of the TV or radio card to the external audio input of the sound card. If you have not yet configured your sound card, select Configure Sound Card to configure it as described in Section 2.4.13, “Sound”.

If your TV or radio card has speaker jacks, you can also connect the speakers directly without using 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.

When editing a configuration, you can also configure the TV stations by clicking TV Channel. Set the proper TV Standard and Frequency Table for your area and click Scan the Channels. A list of stations appears. After scanning has been completed, click OK to return to the configuration dialog.

2.4.13. Sound

Use Hardware+Sound to configure a sound card. Most sound cards are detected automatically and listed. Select the one to configure or modify then click Edit. Use Delete to remove a sound card. This deactivates existing entries of configured sound cards in /etc/modprobe.d/sound.

Click Other to open a dialog in which to customize the sound module options manually. With Add, configure additional sound cards. If YaST detects another sound card, select it then use Edit.

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 files /etc/modprobe.d/sound and /etc/sysconfig/hardware.

If YaST is unable to detect your sound card automatically, proceed as follows:

  1. Click Add to open a dialog in which to select a sound card vendor and model. Refer to your sound card documentation for the information required. Find a reference list of sound cards supported by ALSA with their corresponding sound modules in /usr/share/doc/packages/alsa/cards.txt and at http://www.alsa-project.org/~goemon/. After making your selection, click Next.

  2. In Setup Dialog, 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 can adjust the output volume and play a test sound. Advanced setup with possibility to change options allows you to customize the sound card options manually.

    In this dialog, there is also a shortcut to joystick configuration. Click it and select the joystick type in the following dialog. Click Next to continue.

  3. In Sound Card Volume, test your sound configuration and make adjustments to the volume. You should start at about ten percent to avoid damage to your speakers or hearing. A test sound should be audible when you click Test. If you cannot hear anything, increase the volume. Press Continue to complete the sound configuration. The volume setting is then saved.

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, check Start Sequencer. This way, the modules for sequencer support are loaded along with the sound modules.
