Public bug reported:

After the fresh install, I properly saw the boot progress with the
plymouth Xubuntu theme up to a step where the screen has no more the
progress image but a odd screen content which doesn't represent anything
(from my knowledges).

Next, I could get a virtual console (tty1) after many attempts of key
strokes (CTRL-ALT-F1).

Each ~10-30 seconds I get a console message in this screen like :
"nouveau E[Xorg[966]] failed to idle channel 0xcccc0001 [Xorg[966]]"

I achieved to log in and execute 'sudo initctl stop lightdm'.

The 'ps axf' command showed that X was still running.

I first tried the command "sudo kill 966" with no success.

Then I executed the command "sudo kill -KILL 966".

Finally, I decided to install the proprietary driver with the command
"sudo apt-get install nvidia-current".

I reboot and the problem disappeared.
