Bug Description

Hello guys,
 I have an issue with Gnome and gdm. I am using time to time dual screen, my normal notebook screen and an external one. Both of them work on the same resolution. My notebook is Lenovo T61 with Intel graphics. In general everything works on this Lenovo using Ubuntu, but in the case of dual screen or clone doesn't, not right anyway. If I use dual screen, and for example Im logging out, the gdm totally crashes or the system goes in Safe-mode screen, somehow the resolution gets totally weird or no X windows anymore.

I got this message out of dmesg when gdm crashed:

[13318.855454] gdm[6737]: segfault at 7672657f eip b7805b52 esp bf85f4f0 error 6

In rest I don't know what to do or what could be the issue. Please help out if you can.

Thank you.
