First, please try removing these shell extensions: ['system-moni...@paradoxxx.zero.gmail.com', 'workspace-g...@mathematical.coffee.gmail.com', 'windows-alt-...@tglman.org']
If that solves the problem then this is a bug in an extension and not in gnome-shell. Otherwise, please look in /var/crash and tell us if you find any .crash files there. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1779846 Title: Pressing Alt+Backslash locks up all windows (no focus) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1779846/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
