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.
