I just installed Ubuntu 11.10, i386 on my Dell Latitude E6500. The installation was fine, but then X11 didn't start.
(EE) Failed to load module "nv" (module does not exist, 0) ... (EE) NVIDIA(0): Failed to load NVIDIA kernel module!
I installed nvidia-current
apt-get install nvidia-current
but no luck.
Just in case: 10.10 works just fine.
