I know there have been a number of posts/articles about getting NVIDIA to work under Ubuntu. Yet after extensive searching I haven't found one that has gotten me where I need to be.
Here is my situation: Ubuntu 12.10 installed on Intel I7 (non-SandyBridge) with NVidia 285GTX video card. After initial Ubuntu installation I installed Linux headers, turned off X/Nouveau and ran the NVidia shell script to install the 310 version drivers.
Next I installed Gnome 3 and switched to it as desktop.
Result: sluggish desktop performance. Details in System Settings shows graphics driver Gallium 0.4 on llvmpipe (LLVM 3.2, 128 bits).
glxinfo shows same as above for renderer.
$DESKTOP_SESSION shows ubuntu.
lspci VGA section shows: 02:00.0 VGA compatible controller: NVIDIA Corporation GT200b [GeForce GTX 285] (rev a1)
Tried restarting gdm with no result.
Any ideas how to get the renderer to use the NVIDIA hardware rather than Gallium software?
