Xorg Crashes on Logout When Using nVIDIA Restricted Drivers

[Hossein Atashi]

Binary package hint: xserver-xorg

I'm using Intrepid Ibex on a Lenovo ThinkPad T61 with a nVIDIA Quadro 140M GPU. When the restricted drivers are deactivated, everything goes fine, but when using the restricted drivers, whenever I try to logout or restart the X server by any means (e.g. Alt-Ctrl-Backspace) the X servers stops but fails to start again. I have tried using a xorg.conf generated by nvidia-settings but didn't help.
I'm attaching my /var/log/Xorg.0.log. Apparently there is not any errors (indicated by EE) in the log.
It's really strange because on bootup everything goes fine but only on X server restart, it crashes.

If you think it can be of any help, feel free to have a look at my xorg.conf too.

I can confirm this problem, with the same setup.

Well, I can add that the problem only occurs when using the new (177) nVIDIA driver and with 173, everything works fine. I'm not sure anymore whether I should have reported this bug as a xorg package bug. But I hope somebody find a fix for this soon.

Confirmed - same graphics card: NVIDIA Quadro 140M on Lenovo R61 laptop.
