Compiz segfault during login on NV GTX560 after enabling Xinerama

[Jay Miller]

Binary package hint: compiz

After starting X, reaching the user login screen and logging into the default "Ubuntu" profile (which uses Compiz), Compiz will crash if Xinerama is set to '1' in xorg.conf. Logging in with 'no effects' will - naturally - work just fine. Logging in with the default "Ubuntu" profile when Xinerama is set to '0' will also work just fine. Note that X itself does not crash, rather compiz. Attempts to troubleshoot included regenerating xorg.conf, removing nouveau, tweaking xorg.conf settings and using the next most recent nvidia driver.

from dmesg:
compiz[15093]: segfault at 58 ip 00007fb486bfbc51 sp 00007fff1ac1ce68 error 4 in libnvidia-glcore.so.270.41.06[7fb485c69000+144e000]

OS: Ubuntu 11.04
Card: NVidia GTX560
Driver: nvidia-current_270.41.06-0ubuntu1
Compiz: compiz_0.9.4+bzr20110415-0ubuntu2

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on your current version. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at ubuntu.com). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. If you are unable to test the development version, please let us know if you are able to reproduce this issue on Ubuntu 11.10.

Thank you for your help and patience.
