I don't have Regolith, just gnome-flashback. For me, similar behavior was caused by a bad ~/.config/monitors.xml (file itself was ok, but there were maybe too many definitons, maybe some of them were conflicting?).
Deleting it didn't work (crash at login). But changing a thing forth and back in Display settings and hitting Apply fixed it for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2086706 Title: gnome-flashback crashes on idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/2086706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
