I'm not sure if my problem is exactly the same as this, but I also get
heavy flickering and graphic bugs that was not present in 11.10.
My work around:
I compiled and installed the nvidia-current package from 11.10 (version
280.13-0ubuntu6.1) for 12.04 amd64.
Then I had to add the following to my /etc/X11/xorg.conf
Section "ServerFlags"
Option "IgnoreABI" "1"
EndSection
I also added the following line to /etc/modprobe.d/blacklist.conf (Not sure if
this is necessary)
blacklist nouveau
So far I have had no flickering.
My compiled version of the driver can be found at: http://www.sandin.cx
/nvidia-current_280.13-0ubuntu6.1_amd64.deb
