Similar problem here, only happens occasionally, started today (haven't added any software / done any updates recently).
X crashes completely, screen blacks out, have to login again. Happens when I access some rather large dev. page (can't show it) in FireFox 3.0 (Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9) Gecko/2008061017 Firefox/3.0), but also consistently on the page mentioned in the post above this one: "http://ubuntuguide.org/wiki/Ubuntu:Gutsy#What_to_do_if_Ubuntu_freezes"; Relevant bit from /var/log/syslog: Jul 15 11:03:21 bollo kernel: [10184.118085] Xgl[6308] trap divide error rip:43bec0 rsp:7fffd004a930 error:0 -- segfault error 6, and trap divide error https://bugs.launchpad.net/bugs/225338 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
