compiz crashed with SIGSEGV in _wordcopy_fwd_aligned() from __memmove_sse2() from ? /usr/lib/nvidia-current/libnvidia-glcore.so.295.40 from glXBindTexImageEXT

[D. Wegener]

I upgraded my system to 12.04 today. After reboot and login, my desktop initially displayed then a slow black screen wash happened from top to bottom. I waited several seconds and eventually the desktop came back with no panel or launcher. I received a crash popup and tried to send it, but the crash reporting process never completed.

I was able to restart X and login using the 2d desktop. The following is an excerpt from a crash file in /var/crash I can send the entire crash file if needed it is over 7mb.:

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

I am thinking this bug might be fixed by the fix for bug 927168, which was released to quantal a few days ago.

[Daniel van Vugt (vanvugt)]

Here's a more recent stack trace:

[Sam Spilsbury (smspillaz)]

I think we could be providing an invalid image to the driver. Not sure.

[Sam Spilsbury (smspillaz)]

Hmm, nope. I've removed UnityMTGrabHandles::glDraw from the description as we're just painting a regular old tfp texture from xcomposite. This sounds like some kind of weird problem in the driver.

Can the reporters run nvidia-bug-report.sh ? It should be in your PATH by default.

[Jussi Pakkanen (jpakkane)]

Here's my NVidia bug log.

[Daniel van Vugt (vanvugt)]

Assuming comment #4 is an accurate indication of this bug, it looks like this was fixed in bug 1060327. So let it be a duplicate for now.
