Xorg.conf Config File Details

Once you have all the devices and their device files figures out, it is time to actually edit the
/etc/X11/xorg.conf file. It is easiest to start with a multi-display configuration using both graphics
cards and just edit the xorg.conf file for that config. Multi-display configurations can be set up easily
and interactively using HP's graphics configuration tool, vizconfig. Just use vizconfig to configure the
number of monitors that you plan on using, ie, one display on each graphics card (1 card per user)...
or twin-view on each graphics card (2 displays for each user).
The steps to using vizconfig are outlined below:
Login as root.
1.
Launch vizconfig using desktop icon or by executing /opt/hp/viztools/bin/run_vizconfig.
2.
Select display arrangement from the pull-down labeled "Selected Display Arrangement" such as
3.
3x1 or 2x2.
Once a display arrangement is selected, you can also set different options in the "Options" tab.
4.
Your options are:
SLI Multiview (Xinerama) - this enables/disables 2d/3d Xinerama
•
Use twinview where possible – enables/disables twinview
•
Now its time to setup the different displays/monitors. The different displays are shown in the
5.
picture of the current selected display arrangement along with how the graphics cards are
connected to those displays.
Select the display via the "Selected Display" pull-down. The picture of the display arrangement
6.
will be updated to highlight the selected display.
Now set the resolution for this display with the Display Resolution slider.
7.
If you want the display to be connected to the other connector on the graphics card, just click the
8.
"Swap Left_Right Monitors" button. The picture of the display arrangement will be modified to
reflect this change.
Repeat steps 6 thru 8 as needed for each display.
9.
Press "SaveConfig" button to save the changes to the /etc/X11/xorg.conf file.
10.
NOTE: Any edits made to X config file after running vizconfig, will not be used by vizconfig next
time it is run.... you will need to apply these edits each time vizconfig is run.
Once you have a working multi-display /etc/X11/xorg.conf file, you need to make some edits to it to
get multi-seat working. The first edit is to add device sections for the keyboards and mice... the
screens should already be there from the vizconfig setup. Here is the proper way to configure these
input devices on release 6.9 or later versions of the Xorg Xserver. First, for each keyboard, construct
an InputDevice section for your /etc/X11/xorg.conf file like this:
Section "InputDevice"
Identifier "KeyboardN"
Driver "evdev"
Option "Device" "/dev/input/eventX"
EndSection
Where N is the sequential keyboard number and X is the event handler identified during the setup
phase above.
Here is the xorg.conf section that describes the PS2 Console Keyboard:
Section "InputDevice"
Identifier "Keyboard0"
Driver "evdev"
Option "Device" "/dev/input/event0"
