If the problem gets worse over time then it might be memory related. Please run:
ps auxw | grep gnome-shell and tell us what you see when it is (a) fast and (b) slow. If that's the problem then it is likely an extension is to blame. So make sure you have uninstalled ALL of them, at least temporarily as a test. ** Tags added: nvidia -- 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/1869568 Title: Unlock takes a long time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1869568/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
