You have been subscribed to a public bug:

Since kernel version 2.6.30-9.10 the external monitor doesn't get properly detected when it was disconnected before disabling it before, when using KMS.
2.6.30-8.9 was the last version where it worked properly.
intel driver version: 
- 2.7.99.1+git20090602.ec2fde7c-0ubuntu2 (Karmic)
- 2.7.99.901+git20090630.170cae0c-0ubuntu0sarvatt (latest git)


Steps to reproduce the bug:
1. screen is on LVDS of the notebook
2. connect external VGA
3. activate external monitor: xrandr --output VGA1 --auto
4. disconnect external monitor
5. deactivate external monitor: xrandr --output VGA1 --off
6. again connect the VGA plug
=> xrandr --query shows: VGA1 disconnected

after that it is impossible to get the external monitor working.
The only solution is to reboot the system.

** Affects: xserver-xorg-video-intel (Ubuntu)
