Calling "gsd_xrandr_manager_apply_configuration (mgr, error);"
unconditionally from plugins/xrandr/gsd-xrandr-manager.c handle_fn_f7
will restore the existing configuration as well. But fn-f7 cycling
through display modes stops working, as the existing configuration will
always take precedence.
Unfortunately I don't think gnome-settings-daemon has any idea that the
system is being docked. So only conditionally calling
apply_configuration from gsd-xrandr-manager.c handle_fn_f7 will most
likely not work.
Is there any other place in the system that is run only when a system is
being docked? From there we could call ApplyConfiguration via dbus.
Alternatively the fn-f7 modes should contain the saved configuration, the
configurations are generated upon docking in
generate_fn_f7_configs:
g_ptr_array_add (array, gnome_rr_config_new_current (screen));
g_ptr_array_add (array, make_clone_setup (screen));
g_ptr_array_add (array, make_xinerama_setup (screen));
g_ptr_array_add (array, make_laptop_setup (screen));
g_ptr_array_add (array, make_other_setup (screen));
g_ptr_array_add (array, gnome_rr_config_new_stored (screen, NULL)); /*
NULL-GError - if this can't read the stored config, no big deal */
