Bug Description
Binary package hint: xserver-
My laptop hangs when I just connect an external monitor to it. This is even before I configure any type of mirror screen or extended desktop. The instant VGA connector touches the port, the system is lost. The only way out is by hard reboot. I have tried 'Ctl-Alt-Backspace' (after enabling it), ssh-ing into the laptop but nothing works. This did not happen in jaunty.
I use my laptop to display presentations regularly so this is a very big loss of usage at work.
This is a very bad regression. People can inadvertently loose all unsaved data just in the course of trying to display externally.
Enabling/Disabling Compiz does not seem to make any difference.
I looked at Bug:438000 which seems to be compiz related and happens AFTER somebody tries to configure the screen for external monitor.
Please let me know what other debug information may be needed for this.

Could you check if this is the same as bug 500999? If it freezes instantly, it probably isn't. It is more likely to be something like bug 319717. Sony laptops have a history of doing strange non-standard things. Could you start the computer in recovery mode (so there will be no xorg running) and check if connecting the external monitor still freezes the system.
