Here is the lightdm log file pulled from /var/log/lightdm/lightdm.log. At 98.76s, I logged out of my session, but didn't get a log-in screen again (black screen on both monitors).
At this point I killed the process (28882) so that I could downgrade lightdm again (from ctrl+alt+F1) and log back in. Not sure if it's applicable, but the log that was generated was with kernel version 3.2.0-19-generic running. Also, the proprietary graphics driver I'm running at the moment is Nvidia v340.76. I also tested with v340.65 but still ran into the 100% cpu usage with the newest proposed lightdm service. ** Attachment added: "lightdm log file" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1431654/+attachment/4343680/+files/lightdm.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1431654 Title: lightdm (1.2.3-0ubuntu2.6) 100%/high cpu usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1431654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
