Via dup: https://bugs.launchpad.net/ubuntu/+source/gnome- shell/+bug/1886672
Adding some additional testing to my above comments. *When second monitor is not removed*, i.e. remains connected, lock screen/suspend resume all restore display as expected after latest updates as suggested by Daniel in above linked dup. Plugging display out, gnome adjusts to single screen settings as expected. But plugging back the second monitor in does nothing. Restarting gnome-shell resets displays as expected. I.e. working. Also note not working in #26 regarding resuming laptop after plugging in screen. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1877774 Title: gnome-shell crashed with SIGSEGV in _st_theme_node_ensure_background() from st_theme_node_paint_equal() from st_widget_recompute_style() from st_widget_style_changed() [when locking the screen] [usually due to dash-to-panel] Status in GNOME Shell: Unknown Status in gnome-shell package in Ubuntu: Fix Released Status in gnome-shell source package in Focal: Fix Released Bug description: [ Impact ] GNOME shell crashes on extensions loading / updates [ Test case ] - No clear test case, normally may happen during screen locking/unlocking - But crashes should be monitored at https://errors.ubuntu.com/problem/4127e7e714fd28c090da0220de2ff06e71274eda [ Regression potential ] Stylesheet memory could be leaked --- Seems to be reproducible Suspend the computer Start the computer from suspend Start chrome gmail.
