I was getting the same error as Ian, JPM ( #775705) and qwazi on my 64-bit Maverick with nVidia binary drivers (260.19.06). No compiz here, but extensively using VMware Player with 3D acceleration.
According to a hint by Paul de Vries (http://vimeo.com/groups/cinelerra/forumthread:236340), I have updated the nVidia drivers. I took 270.41.06 from ppa:ubuntu-x-swat/x-updates. I will report whether it stopped crashing. ** Attachment added: "Xorg.crash.log" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/740785/+attachment/2124313/+files/Xorg.crash.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740785 Title: Caught signal 11 (Segmentation fault).
