Comment 29 for bug 980298

I installed a 295.49-0ubuntu0.1 deb via the link provided by Ben A, changed my xorg.conf display driver from "nouveau" to "nvidia" and rebooted. I got a text login screen and found a segfault in Xorg.0.log (see below). Let me know if more from my log file would be useful.

Here was the output of "dpkg -l" at the time of the segfault:

I've since switched the xorg.conf display driver to "nouveau", run "apt-get purge nvidia-current", and rebooted---I'm back to "normal".
