update: A workaround for me is: log in, set screen to external only, get flickering.
Then, while staying logged in, switch to guest session, and back to own user session -> No flickering appears. When you cycle through display modes, flickering reappears, but you can redo the same workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1209315 Title: external screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1209315/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
