Same problem on Intel integrated gfx card. I have 4k monitor connected over DP-1 (to have 4k @ 60Hz). In my case after the crash all apps (Google Chrome, terminal, ...) are killed. Additionally scaling-factor and refresh rate are set to incorrect values. Scaling-factor is set to 1 and refresh rate is lowered to 30Hz.
Scaling-factor can be fixed with "gsettings set org.gnome.desktop.interface scaling-factor 2" However there is no way to set fixed refresh rate to 60Hz. I have to reboot whole system. So basically after "blank screen" system has to rebooted. -- 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
