Code review comment for lp:~vanvugt/unity/fix-742544-trunk

Note that in the 5 steps described in this fix, steps 1-4 are already built into gdk_screen_get_primary_monitor().

If we are willing to remove step 5 (which I maintained for compatibility with the oneiric default behaviour), then most of UScreen::Refresh() can be deleted and replaced by: primary_ = gdk_screen_get_primary_monitor(screen).
