NOTE: October 18, 2011. I see that this page is the top hit on my blog this week. I think if you’re looking for more up to date information, you should see my current opinion on Compiz on Kubuntu here.
After months of waiting for things to be resolved with the nvidia drivers and such, I finally buckled down to see if I could get compiz running again smoothly on Ubuntu 11.10. Happily, I can report that the answer is yes!
Using the latest packages, the trick was to follow some advice in this thread.
First, you need to blacklist the nouveau driver. It hasn’t been working for me, and it has been preventing the nvidia driver from being loaded.
sudo nano /etc/modprobe.d/blacklist.conf
add “blacklist nouveau” to the end of the file, then save and close it.
Next, you do need to update initramfs and reinstall the nvidia-current driver:
sudo update-initramfs -u -v sudo apt-get install --reinstall nvidia-current
From that point on, a simple reboot (and making sure that your xorg.conf actually uses the nvidia driver) should be enough to get you back into Xorg with the Nvidia binary blob… and by opening a terminal and typing:
You should be good to go again. Things appear to be stable, but I’m sure this will need a lot more testing before I switch back to compiz/kde/nvidia as my default setup.
