I can confirm this. I'm also experiencing random X crashes. here's my Xorg log, the first lines in the backtrace are the same. I'm on a switchable graphics laptop (Intel/ATI) and I0'musing proprietary ATI 11.4 drivers from their website. This certainly happens when I'm using the Intel card (power saving mode).
Let me know if there are more informations I can provide. ** Attachment added: "Xorg.1.log.old" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/780527/+attachment/2125099/+files/Xorg.1.log.old -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/780527 Title: X crashes randomly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
