I have the same issue, running on a laptop with a dual monitor splitter plugged in my displayPort.
The crash happens under Wayland and XOrg. I've disabled auto-source selection on the monitors. The crash happens only when I log-in after the session has been locked. It also happens when I press the reset switch on my displayPort splitter. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1722353 Title: Screen blanking and/or screen lock crashes gnome-shell user session on wayland - Ubuntu 17.10 beta To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1722353/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
