Just poking in to say this is still happening, and not magically fixed by Artful's release date. It happened today, but trying to ubuntu-bug the crash file failed. (It just quit when I clicked Continue.)
One difference today: Thinking maybe my screen-sleep woes were partly because of gnome shell being in lock mode, I tried instead disabling screen lock and suspend and just using ye olde x11 screen blanking to standby, ie: xset dpms 1200 0 0. It still died, leaving a crash file reporting this same error, at the time I tried to wake things up again. I think again, supported by the description of this bug, it was probably due to slowness in monitors waking up, or one of them having problems waking up fully at all, then gnome-shell responds ungracefully - perhaps even disgracefully - to the change in monitors. gnome shell is so damn fragile. gnome-shell 3.26.1-0ubuntu5 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1723620 Title: gnome-shell crashed with SIGSEGV in meta_window_update_for_monitors_changed() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1723620/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
