[xmonad] Startup Arguments

[Chris Bell]

Hi,

I run Xmonad on my laptop, where I sometimes have multiple displays
(when I'm at my desk). As a result, I have two Xmonad configs - one
for a single screen, and one for two screens, which spawns extra
copies of some programs (xmobar, for example). However, to keep
everything playing nice, I have to manually swap out the config each
time I switch my monitor setup by editing my xmonad.hs.

I tried adding code to use xrandr to detect how many screens are
active, and execute the function accordingly, but this just caused my
X session to break.

My xinitrc script knows how many monitors are active, but I don't know
how to pass that to Xmonad on startup. Is there a facility to pass
arguments to Xmonad at startup from xinitrc? Or did I simply miss
something in the documentation?

Thanks!
