Public bug reported:
When I connect the external monitor the image is shown on the external
display but it freezes (on both displays); after I unplug the external
display the following errors are logged (not sure it is related to the
freeze):
Jul 5 09:19:39 xps gnome-shell[10252]: meta_display_get_monitor_in_fullscreen:
assertion 'monitor >= 0 && monitor < n_logical_monitors' failed
Jul 5 09:19:39 xps gnome-shell[10252]:
meta_monitor_manager_get_logical_monitor_from_number: assertion '(unsigned int)
number < g_list_length (manager->logical_monitors)' failed
Jul 5 09:19:39 xps gnome-shell[10252]:
meta_workspace_get_work_area_for_monitor: assertion 'logical_monitor != NULL'
failed
The external display is connected via a thunderbolt port and an adapter
to HDMI.
