7.4 Hardware
New hardware must first be installed or connected as directed by the
vendor. Turn on external devices 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.
7.4.1 Infrared Device
Configure an infrared
device with . Click to begin configuration. You can configure
and here.
7.4.2 Graphics Card and Monitor
Configure graphics cards and monitors with .
It uses the the SaX2 interface, described in
Section 7.13,
SaX2.
7.4.3 Printer
Configure a printer with . If a printer
is properly connected to the system, it should be detected
automatically. Find
detailed instructions for configuring printers with YaST
in Section 24.4,
Configuring the Printer.
7.4.4 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 . 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
to check if the current
settings work before they are saved permanently in the system.
WARNING: Configuration of the Hard Disk Controller
It is advised to test the settings before making them permanent in the
system. Incorrect settings can prevent the system from booting.
7.4.5 Hardware Information
Display detected hardware and technical data using .
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 . Select the desired directory
and filename then click to create the file.
7.4.6 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
. 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 Enterprise 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:
DMA (direct memory access) means that your data can be transferred
directly to the RAM, bypassing the processor control.
7.4.7 Joystick
Configure a joystick connected to the sound card with
.
Select your joystick
type in the list provided. If your joystick is not listed,
select .
After selecting your joystick, make sure that it is connected then
click to test the functionality. Click
and YaST installs the required files. After
the
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
to return to the module and
to complete configuration.
If you have a USB device, this configuration is not necessary. Plug in the
joystick and start using it.
7.4.8 Keyboard Layout
To configure the keyboard for the console, run YaST in text mode then use
.
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 by pressing
keys on the keyboard.
Fine-tune the settings by clicking
.
You can adjust the key
repeat rate and delay and configure the start-up state by choosing the
desired settings in .
For , enter a space-separated
list of devices to which to apply the Scroll Lock,
Num Lock, and Caps Lock settings.
Click to complete the fine-tuning. Finally,
after all selections have been made, click
for your changes to take effect.
To set up the keyboard for the
graphical environment, run the graphical YaST then select
. Find information about the graphical
configuration in Section 7.13.3,
Keyboard Properties.
7.4.9 Mouse Model
When configuring the mouse for the graphical environment, click
to access the SaX2 mouse configuration.
Refer to Section 7.13.2,
Mouse Properties for details.
To configure your mouse for the text environment, use YaST in
text mode. After entering text mode and selecting
,
use the keyboard arrow keys to choose your mouse from the provided
list. Then click to save the settings and exit
the module.
7.4.10 Sound
Use
to configure a sound card.
Most sound cards are detected automatically and listed. Select the one to
configure or modify then click .
Use to remove a sound card. This deactivates
existing entries of configured sound cards in
/etc/modprobe.d/sound.
Click
to open a dialog in which to customize the
sound module options manually. With , configure
additional sound cards. If YaST detects
another sound card, select it then use .
The volume and configuration of all sound cards installed are saved
when you click . 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:
-
Click
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
https://www.alsa-project.org/~goemon/. After making
your selection, click .
-
In , choose the configuration level in
the first setup screen. With
, 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
, you can adjust the
output volume and play a test sound. allows you to customize the sound
card options manually.
