[xmonad] Dual Head Support in Xmonad

Hi, all.

I'm trying to get xmonad running on my Ubuntu (Hardy Heron) system. I am using Xrandr 1.2 to set 
up dual monitors, but xmonad doesn't seem to like this arrangement. (The first window gets 
stretched across both monitors...)

Looking on the web I see that this is a recurring problem:


The OP of this thread was using Xinerama, which I've never been able to get working on my 
system, and anyway seems to be deprecated in favour of Xrandr.

But I'm not sure if xmonad supports for dual-head systems under xrandr? This page:


suggests not.

Can someone tell me if I need to concentrate on getting Xinerama working, or if it is possible 
to get sensible behaviour from xmonad + xrandr on a multi-head system?

Thanks in advance,


p.s. I'm using the pre-built Ubuntu packaged version of xmonad (0.6-3), along with 
libghc6-xmonad-contrib-dev (0.6-4) and libghc6-xmonad-dev (0.6-3) downloaded via the Synaptic 
Package Manager. I'm hoping that the difference in version numbers is not significant!

p.p.s. if I do "xmonad --version" at a prompt, I'm told I have version 0.5! So I'm not 
absolutely sure which version I've got on my system....
