I have this same problem on 18.04. It's very noticeable that when my network has no DNS working, screen unlock takes a long time - as much as a minute or two.
I notice this because I often manually configure my network to do DNS lookups over an SSH tunnel. If I just close the lid of my laptop it locks and then goes to sleep, and of course when I open it again the SSH session is down & I have no DNS. In this state, the screen unlock is really slow. If I shut the lid not in this state, screen unlock is quick as normal. I use an Xorg session. -- 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/1774188 Title: Unlocking the screen takes 5 seconds in Xorg sessions (not so much in Wayland sessions) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1774188/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
