I think I found what does it on my machine. I did a fresh install and rather than my usual mods I only installed the kubuntu restricted extras package and firefox. I'd normally switch the network manager with wicd but I left this out. One other package I had before was Skype Beta 2.1.0.81-1 which is meant for 8.04+. I went all week without getting the error (it was normally several times a day) then an hour after I installed the Skype beta I got an X crash the same as I had been getting.
I notice the package drops a file /etc/dbus-1/system.d/skype.conf - perhaps the changes in there cause the error. I wouldn't know what to check from here but maybe someone with the right skills can check this out? -- X server crashes randomly https://bugs.launchpad.net/bugs/573957 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
