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-X, which is subscribed to mesa in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
