Rocko, Sorry to hear about this problem. However with a large number of open bugs with similar symptoms we can't pin down the exact cause of this one without more information.
If you can then please try logging into the machine remotely (e.g. via SSH), and run 'journalctl -f' before reproducing the bug. Do you see any log messages that are helpful? How about from 'dmesg'? Also while logged in remotely, after reproducing the problem please check if the gnome-shell process is still running. And if so then please run 'kill -ABRT' on it to generate a crash file which you can later upload with 'ubuntu-bug' or 'apport-cli'. ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => High ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730540 Title: gnome-shell freezes after resume then unlock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1730540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
