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
