Jan Rathmann, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please just make a comment to this.

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Blank screen during system startup with Precise/Nouveau

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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
