apport information ** Tags added: apport-collected ubuntu
** Description changed: 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.
