I haven't managed to reproduce it in the last week. The log files get rather large but attaching current, as may help.
Not consistently reproducible but above describes it as best, also sometimes happen when machine is unplugged from power - or plugged in - or the battery changes levels.... all of it's involving X, gnome-session, power management, dbus and the kernel - and some kind of interaction between these all. basically, either X suddenly aborts (to login prompt) or the machine powers off. It's not running hot. To reproduce somewhat more consistently: run something that uses 100% CPU for a period of time. anything with flash and epiphany or konqueror (mozilla handles flash better) - although latest flash version seems better. Many mono/C# packages, especially if windows programs many windows programs (wine) - but only if directx. (these problems reduced when I dismantled laptop and cleaned it thoroughly, so I suspect heat warning became a dbus fatal error) note that problem is inconsistent, There is one 100% way to reproduce it: dbus fatal error I'm going to experiment with that more when I finish my current contracts. Currently I try to avoid the behaviours that trigger the crashes as I don't want to lose more work. There is no difference between this Xorg.log and one from a crash - from what I've seen. The only message I remember seeing is a session close - so it's likely not X itself that's doing this, although it could be the i865 driver which isn't 100% although it's improving of late. log file excerpt included above is all information available, without compromising security. (although I can provide longer excerpt including whole boot sequence, if you wish) Any suggestions at all on how to debug dbus problems, gnome-session problems and power problems - WITHOUT disruption to the system - would be appreciated. ** Attachment added: "current Xorg.0.log.old as it may reveal sufficient about hardware" http://launchpadlibrarian.net/25569417/Xorg.0.log.old -- session crashing randomly - may be power management issue https://bugs.launchpad.net/bugs/341344 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
