I confirm this bug. This screensaver often freezes system. Compiz.real process eats all cpu and X become unresponsive. This issue is pretty old -- it was reproducible with old compiz or beryl.
System is not dead after hang: it can be recovered by logging in via ssh/telnet and killing compiz.real process. Rarely system can be recovered by switching to console (C-A-F1-6) -- you have to wait few minutes for that. Seen this bug in Ubuntu Dapper-Edgy-Feisty-Gutsy. Xorg.0.log, dmesg, .xsession-errors never contain any information about hang. ** Changed in: gnome-screensaver (Ubuntu) Status: New => Confirmed -- Braid screensaver cause desktop to freeze up https://bugs.launchpad.net/bugs/97107 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
