I have similar problems: I'm running feisty (upgraded it from edgy). But I have a NVIDIA card. Beryl with XGL is installed, but KWin as window manager is loaded, not Beryl. After a few minutes (15-20) leaving my computer the freeze happens. Programmes like Amarok (while playing music) and Azureus still work, but I cannot press any buttons and do mouse clicks. Pressing the Power-Button on my computer's case shows the Logout / Shutdown / ... buttons.
So my Linux isn't usable for me at the moment! ** Attachment added: "dmesg" http://launchpadlibrarian.net/8136211/dmesg_output.txt -- ubuntu randomly freezes https://bugs.launchpad.net/bugs/117651 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
