To clarify: This behaviour occurs after opening the lid of my notebook, which means I haven't actually unlocked the device. Upon opening, it greets me with the previously displayed content with intermittent black flickering.
However, when going to login screen (ctrl-alt-F1) or lockscreen (super+L) I can unlock and make the GUI responsive again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813139 Title: Screen unlocked after resume, black flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1813139/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
