I have the same problem as gambacherkalben: nvidia driver on Fujitsu E8410H produces blank screen.
- GeForce 8400M G (128MB dedicated)
- Ubuntu Gutsy - AMD64/EM64T
- nvidia driver 100.14.11
- auto-generated (by nvidia-xconfig) xorg.conf (attached). Attempts to tweak it didn't make a difference.
One thing I noticed in the log (attached) is that driver incorrectly recognized video memory size as 512MB instead of 128MB
I tried to set VideoRAM option, but it was ignored. There are no errors in the log that I can see, xstart doesn't fail, but screen remains blank.
