>From your logs it appears you have a few "Permission denied" errors on files within your home directory. This can happen easily as a consequence of running some things as root in a previous session.
To fix this, please log into a VT (or MATE or Cinnamon) and run: sudo chown -R $USER ~ or more specifically: sudo chown -R username /home/username That should fix your "Permission denied" errors, and possibly this whole bug. ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1733271 Title: Mutter does not run on X11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1733271/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
