One thing that may be related, especially in view of the assertion: I have an external monitor connected to my laptop through a docking station. Gnome-shell repeatedly forgets how I would like the display configured and starts with both screens on. I hit Super+p three times to switch to "Exterior only". After that, starting gnome-tweak-tool and touching its window with the pointer will lead to a crash. (I don't think it's specific to just this program--it's just what led to the crash for me this time around.) Because of the docking station, a large number of outputs show up in xrandr: Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 8192 x 8192 eDP-1 connected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) HDMI-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) HDMI-2 disconnected (normal left inverted right x axis y axis) DP-2-1 disconnected (normal left inverted right x axis y axis) DP-2-2 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 597mm x 336mm DP-2-3 disconnected (normal left inverted right x axis y axis) eDP-1 is the laptop display. > Would it be possible to install systemd-coredump and some relevant-looking > -dbgsym packages (at least mutter, gtk and GLib), reproduce this crash, > and use coredumpctl to get a more complete backtrace?
