This doesn't look like an X issue to me - that EQ overflow indicates that something blocked the Xserver process for long enough for its internal event queue to fill up; this can take much less than a second for a touchpad driver like synaptics. Given that the EQ overflow seems to have occurred many hours before the problem I don't think it's related.
The final line, “[121316.041] ddxSigGiveUp: Closing log” indicates that the X server shut down as expected; this looks like something has asked the server to shutdown, and it's complied. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/900308 Title: Unity crashes after being suspended for >48hrs To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/900308/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
