I am having the same problem on Gutsy as well. My screen saver is not set to "random", but to "popsqaures" (2D screen saver). I believe the machine is entering a sleep/suspend mode and cannot return from it (even though my power management is set to "never do anything"). I saw a similar problems with WinXP in the following link: http://support.microsoft.com/kb/923232
Since the system completely hangs I cannot track the exact package. I would like also to mention that the "system hangs" problem also occurred to me in 2 other occasions: 1. I installed the "bubbles" (or "pop bubbles" or something like that, through the "add/remove ..."). The system hangs completely, ALWAYS, after a while. 2. I installed the game "TuxKart" and the system sometimes hang (mostly not). -- Ubuntu 6.06 screen saver freezes and entire system hangs https://bugs.launchpad.net/bugs/107504 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
