Public bug reported:
I am running ubuntu 11.04 with gnome on a Sony Laptop PCG-7141L, when
connecting a second monitor to the VGA output while ubuntu is running the
system locks up solid, no response from keyboard, video or mouse. I can remove
the monitor and the system stays locked up. If I connect the second display
before booting up everything works fine.
I tried bringing the xserver-intel back to version 10.10 following another user
suggestion but this did not work:
