which seems to be a common complaint this week. I'm tracking those issues in: https://bugs.launchpad.net/ubuntu/+bugs?field.tag=atomic-commit To work around it you should be able to set this in /etc/environment: MUTTER_DEBUG_FORCE_KMS_MODE=simple and reboot. ** Tags added: atomic-commit ** Package changed: ubuntu => mutter (Ubuntu) ** Changed in: mutter (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083984 Title: Screen freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2083984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
