I've had an external monitor in use since Ubuntu 7.10, but my problems haven't yet been solved
The problem is, that my external monitor sometimes fails to light up when login screen should appear. Sometimes it takes several ctrl+alt+backspace -presses before I get login screen.
I assume this could be fixed by editin xorg.conf, but I've got no idea how.
Here's the oddly simplistic output:
Identifier "Configured Video Device"
Identifier "Configured Monitor"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
