I've got a Dell D630 that I've been running with Ubuntu 11.04 and I recently decided to do a web upgrade to 11.10. After the upgrade Blender wouldn't start. I did some investigating and discovered that OpenGL wouldn't start.

First I tried sudo nvidia-xconfig to no avail.

I did an installation of the current Nvidia driver from the command line thus:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current

Having done this I rebooted and discovered that the GUI wouldn't start - it just hung at the first screen. I logged in and tried starting it but only got some errors logged such as this one:

[ 36.090] (II) NVIDIA(GPU-0): Display (LPL (DFP-0)) does not support NVIDIA 3D Vision

Doing some more research I discovered that in 11.10 the NVidia driver was replaced by Nouveau which is evidently incomplete (no 3d).

I discovered that I if I booted 2.6.38-13 the system would start up properly with OpenGL. With that I did some more digging and decided that perhaps I should disable Noveau. I found these instructions on-line:

You have to disable nouveau driver (which I think is the default driver of Ubuntu). First, you have to edit the modprobe blacklist file (terminal: gksu gedit /etc/modprobe.d/blacklist.conf) and add these entries at the bottom:

blacklist vga16fb blacklist nouveau blacklist rivafb blacklist nvidiafb blacklist rivatv

Then reboot and they shouldn’t be loaded. Next, open the Terminal and type ”sudo update-initramfs -u” to create a new image and reboot before nouveau is actually removed.

So far no luck. I'm running 11.10 with the 2.6.38-13 kernel.

What should I try next? If I'd realized it would be this much trouble I would have never done the upgrade.

What is no luck now?. Is it not booting? 11.10 was a pain for me too. It looks like your are blacklisting all Nvidia video drivers from loading... Can you give us the link from the instructions? –  Meddy Mar 10 '12 at 8:23
