[xmonad] telling xmonad that apparently huge screen == 2 screens

[Lara Michaels]

Hi everyone,

I am wondering if I can tell xmonad that what Xorg reports as a strangely wide 2560x1024 screen is in reality two physical 1280x1024 screens. (I am using a Matrox Dualhead2go, which emulates a very wide screen and then divides that signal onto two separate screens.)

Can I tell xmonad what the real screen sizes are, so that maximization and, more generally, screen space management occurs at the correct level (ie, at the level of each 1280x1024 physical screen, rather than maximizing to take over the entire width of my monitor setup!).

Can this be done? I used to be able to do this at the Xorg level when I was using a nvidia video card (using an option called "TwinViewXineramaInfoOveride"), but my new machine has Intel graphics and they don't seem to support this kind of magic... Can I solve it within xmonad?

Many thanks for any help!
