I wasn't having any problems with Ubuntu 18.04 but ever since I upgraded to Ubuntu 18.10 gnome-shell seems to crash two out of every three times the screensaver starts.
I used ubuntu-bug on a /var/crash file but I have no idea what happened to it: it showed me the info in a window and I said go ahead and send it, then it disappeared and I got no email or anything. FYI, I have an older system with an old NVidia card, no 4k monitor although I do use two monitors. I use Xg not wayland. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1729028 Title: gnome-shell crashes when monitor sleeps or is turned off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1729028/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
