Bug#443151: xserver-xorg-video-ati: vt switching activates external VGA monitor [Radeon Xpress 200M]

[Marcus Better]

Package: xserver-xorg-video-ati
Version: 1:6.7.192-4
Severity: normal

This driver causes very strange effects with console switching, which
used to work correctly before. The system is an LG LE50 Express laptop
with Radeon Xpress 200M and an external VGA monitor connected.

1. When the system starts I have kdm on the laptop panel, and the VGA
monitor is in powersave mode.

2. I switch to a virtual console (vesafb). The laptop now shows
garbage in the form of some jumping horizontal coloured lines which
move and flicker a lot. The VGA monitor is now activated and shows the
console.

3. Switching back to X restores the laptop display. Both the laptop
and the VGA monitor now show the same X session (like in clone
mode). (But the colours on the VGA monitor are fine, in contrast to
what I had before, see bug #440174!) However "xrandr" just shows the
following, indicating that it isn't aware that the VGA display is
active:

~$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2304 x 1024
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768       60.0*+
   800x600        60.3
   640x480        59.9
S-video disconnected (normal left inverted right x axis y axis)

4. Switching to console now gives the same console correctly displayed
on both screens.
