Bug#456153: xserver-xorg-video-ati: external VGA display corrupted after killing X

[Marcus Better]

Package: xserver-xorg-video-ati
Version: 1:6.7.196-2
Severity: normal

The external VGA monitor attached to my laptop sometimes ends up with
a distorted screen that is black except for a mouse cursor, which
shows as a thin white vertical bar about five cm high.

This sometimes happens if I kill the X server with
Ctrl-Alt-Backspace. The built-in LCD panel then shows kdm but the VGA
monitor shows the distortion. Switching to text console and back, or
restarting the X server, does not help. I could only restore the
display by rebooting.

The bug occurs quite rarely so I don't know how to reproduce it
reliably, but I have observed it a few times now.

The system is an LG LE50 Express laptop with Radeon Xpress 200M,
kernel 2.6.24-rc4 (i386). I use vesafb on the text consoles.
