Comment 29 for bug 850895

I think i have something like this bug on my system. When i was running the Nouveau driver (now i have the Nvidia prorietary driver installed) the system was booting correct but i don't saw the plymouth splash screen. It was showing a short time (as a purple background, no ubuntu text) popping at the beginning of system boot, but then immediately turned the screen off (no error messages at all) and the boot continued with the screen turned off. The computer booted ok though and the screen turned on again opening lightdm, but no plymouth splash before. At shutdown the splash is showing ok. With Nividia prorietary driver all is as it should be. Ok, both boot and shutdown. System is 12.04 and graphic card GeForce 7600 GS. With commandline option 'plymouth:force-drm' in /etc/default/grub file the splash screen comes up short after the initial purple popup. This is a option but not a good one.
