Public bug reported:

I'm encountering a problem when trying to use my Dell E6400 laptop (i915
video chipset) with an external DisplayPort monitor (DELL3007WFPHC via
an Apple DP->DVI active adapter).

It works fine if I boot up with the monitor connected, but if I start
without it and then plug it in while the X server is running, it
completely locks up X.  When I remove the monitor, X starts working
again and I can continue as if nothing had happened.

I have tested things while only running a basic X server/xterm and the
problem still happens as soon as the monitor is plugged in.  I have
tested the following scenarios:

X running --> plug-in monitor = freeze
X running --> plug-in monitor --> (freeze) --> unplug monitor = unfreezes
X stopped --> plug-in monitor = works (monitor mirrors text console)
X stopped --> plug-in monitor --> start X = works (mirroring/separate/different resolutions/etc all work fine via gnome settings)
(freeze) --> unplug --> (unfreeze) --> stop X --> plug-in --> start X = works (freeze/unfreeze does not appear to have any lasting effects on behavior)

Please let me know if there's any additional info I can provide that
would be of assistance.
