Public bug reported:

Binary package hint: xserver-xorg-video-ati

When attaching an external monitor to the VGA port of my IBM ThinkPad
T42, the output is corrupted if I attempt to extend the desktop to the
external monitor. It works as expected when I set the external monitor
as a mirror of the LCD. The external monitor is an old NEC 15" LCD.

Steps to reproduce:
1. Plug in the external monitor to the VGA port of the laptop,
2. Switch the external monitor on,
3. Press Fn+F7 to enable dual-monitor setup.

Expected behaviour:
The desktop extends to the external monitor.

Actual behaviour:
The display is corrupted on both monitors.
