More symptoms: I can kill gnome-shell with "kill -KILL" from a ctrl-alt terminal. The GDM screen then appears as usual. Logging in again, however, seems to hang on a blank purple screen.
The GDM screen appears normal but moving the mouse over the top-right corner to activate the menu results in EXTREME lag. The menu is usable but doesn't update for dozens of seconds after clicking on it. Could this be a problem with XWayland? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752145 Title: system freeze after full screen video viewing with Xorg on ultrawide monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
