Hmm, the logs don't show anything going wrong. It could still be compiz/unity7 falling back to software rendering incorrectly (which it has been known to do). This would not show up in the X or USC logs, but should be in .xsession-errors. However .xsession- errors is pretty empty compared to what it should look like.
Please run this command and attach the output here: pmap `pidof compiz` | grep _dri Please also look in /var/crash/ for crash files. And if you find a relevant one, please turn it into a bug report by running: ubuntu-bug /var/crash/XXX.crash -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249513 Title: System graphics slow majorily after logout/login To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1249513/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
