Just retested a few times. EVERY time I turn of my monitor, the session dies. Therefore I think my issue might be related to that my monitor has an auto off function.
In dmesg I get the following every time it dies: [108839.489217] gnome-shell[26345]: segfault at 38 ip 00007f58e823ac30 sp 00007fff55008b88 error 4 in libmutter-1.so.0.0.0[7f58e81e8000+141000] -- 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
