The freezes have begun to occur again. I am not able to close windows or open a terminal. I switched to command line using ctrl+alt+f1 and attempted to restart lightdm, but my system remained frozen.
I now believe it has to do with bluetooth as my system has been crash free for the last week in which bluetooth is deactivated. In particular, this line in .xsession-errors in worrying: (bluetooth-applet:2740): LIBDBUSMENU-GLIB-WARNING **: Trying to remove a child that doesn't believe we're it's parent. I'm attaching my most recent xsession errors for the point where the freeze occurred. Any help would be much appreciated. ** Attachment added: ".xsession-errors.old" https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/998108/+attachment/3156032/+files/.xsession-errors.old ** Package changed: pm-utils (Ubuntu) => ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/998108 Title: x220 occasionally freezes when waking up from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/998108/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
