Title:
  Desktop sometimes comes up with undisplayable screen resolution

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  the PC from which I'm sending this report sometimes fails to boot into
  the desktop properly (which desktop environment doesn't seem to
  matter). In the failure case the following happens:

  - The Plymouth Ubuntu splash gets displayed, but it looks distorted.
  Flickering horizontal artifacts are shown all over the screen, it
  looks a bit like a CRT Television with low signal.

  - When the desktop is loaded (via autologin), one can see short
  glimpses of its wallpaper, but after a few second the screen becomes
  black and remains that way. The monitor _does_ seem to receive a
  signal though.

  - It is possible to switch to TTYs and to use them, but they show
  similar artifacts like the Plymouth logo.

  - If I query the display information on the monitor's OSD when the
  screen is distorted, it reports a resolution of 1681x1050 or
  1683x1050, which is 1-3 pixel bigger than the native horizontal
  resolution of the 22" LCD screen.

  Switching between different resolutions via entering 'xrandr --size
  1024x768' blindly, followed by 'xrandr --size 1680x1050' brings up the
  native resolution properly.

  This does not happen on every boot, only in ~10-15% of the cases. I
  was not able to find any pattern so far in the occurence of this bug.
  The only thing I observed is that it _never_ happens when Windows XP
  is started, thus my assumption is that the bug is related to the
  xserver-xorg-video-radeon driver.

  I tried to specify the correct resolution explicitly on the kernel
  command line(adding video=DVI-I-1:1680x1050 ) but this has no positive
  effect.

  The monitor is connected via DVI.

  Below is a video attached that tries to show how the TTYs look when
  this bug occurs. Notice the abnormal blue lines, which are constantly
  flickering.

  Kind regards,
  Jan
