Same problem here on Ubuntu Hardy beta. Ctrl-Alt-Backspace has no effect and Ctrl-Alt-Del has no effect. Ctrl-Alt-F1 and all other keys or key combinations have no effect.
However, I am able to connect to my frozen/locked desktop computer by ssh from my laptop. Top shows compiz.real at 100% CPU. Doing "pkill -9 compiz.real" causes X to restart on my desktop computer. I can then log back in. See this similar bug report: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/186058 I paraphrase: >From this I came to the conclusion that Hardy's compiz must have some hard to >find problems which cause random freezes. Needless to say (but lets say it >anyway), that the problem is not related to xorg configuration or graphics >drivers as the same freeze effects occured in many different machines (with >completely different hw). Any advice on how to provide extra info with this bug report (taking account of the fact that the desktop freezes completely but I'm still able to connect with ssh)? I'm attaching: ~/.xsession-errors, /var/log/Xorg.0.log and the output of lspci -vvnn as separate attachments ** Attachment added: "xsession-errors" http://launchpadlibrarian.net/13137606/xsession-errors -- compiz randomly freezes X https://bugs.launchpad.net/bugs/176589 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
