[Bug 1048261] [NEW] Blank screen during system startup with Precise/Nouveau

[Jan Rathmann]

Public bug reported:

Hello,

if I boot the Precise installation on the PC this report has been sent
from (using Nouveau drivers on a Geforce 2 MX card), the screen stays
blank ("No Signal") during the boot process:

- The grub menu is displayed as usual (allthough in low resolution of 1024x768, while the display's native resolution is 1280x1024)
- Then a few seconds after the text of the grub menu disappeared, the screen goes blank (and turns of a few seconds later due to lack of input signal). In this phase usually the Plymouth boot logo should appear.
- When the display manager is loaded, the screen finally turns back on again/receives input again.

This happens regardless if the system is upgraded or freshly installed.

It is also a regression from Lucid, where the boot process worked
without such problems on this machine (also with Nouveau drivers).

If I set GRUB_GFXPAYLOAD_LINUX=text in /etc/default/grub, I get the
text-only boot logo with correct screen resolution on startup and
monitor doesn't power off in this case.

If I boot using "nomodeset", the graphical boot logo is displayed
correctly but the screen resolution on the desktop is limited to
1024x768 (which is not acceptable).

Kind regards,
Jan
