I've just done a fresh install of oneiric on a Dell Precision m6600 with a nVidia Quadro 3000m. I can log in to Unity 3D, but if I try to start nvidia-settings, I'm told "you do not appear to be using the nVidia X driver". Also, HDMI out doesn't work.
The automatically generated xorg.conf is very short and doesn't appear to be using the nVidia driver:
Section "Device" Identifier "Default Device" Option "NoLogo" "True" EndSection
However, if I run nvidia-xconfig, it will replace the xorg.conf with, among other things,
Driver "Nvidia" line, but when I restart the computer, lightdm won't even start at all.
This all occurs whether I activate nvidia-current or nvidia-current-updates by the "Additional Drivers" GUI. In either case, the GUI says "This driver is currently activated and in use". (obviously not).
How should I go about getting nvidia-settings and HDMI-out to work? Thanks!
