Sure. That's not even crazy, that's normal. Pre-randr-1.3 desktops (and
display managers) typically interpret that as "Primary screen starts at
0,0" so they know which monitor the user wants the main menu button/bar
(or login dialog) on. (Explicit SetPrimary/GetPrimary requests were only
added in randr 1.3)
