Hi Andreas, > Does it already work with just this minimal xorg.conf:
Yes I just confirmed having this single section in xorg.conf makes the
problem go away:
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
The xorg.conf generated by nvidia-xconfig also had "ServerLayout"
"InputDevice" "Monitor" and "Screen" sections.
I have not noticed any problem with these sections removed.
