Kernel: Version 2.2.14
Symptom:
Sometimes the screen is not centered after the installation, you have to move the mouse to the middle of a "virtual screen" to see the X11 screen.
Cause:
Some framebuffer drivers are broken, they don't send the correct screen parameters to the X server. This affects the ATY Mach64, Matrox and ClGen driver.
cat /proc/fb
Solution:
There is no general solution for that problem, its just a bug.
Use the tool xsfbswitch
from the SuSE menu in the KDE panel to fix the screen resoltion. The easiest way is to increase the color depth to 16 bit. This will initialize the framebuffer device after the next reboot and the screen is centered.
The script /usr/X11R6/lib/xsfb/xsfb.init
from the xsfb.rpm package will be executed at boot time and setup the screen parameters.
