[xmonad] xmonad from gnome-session-2.26

[Joachim Breitner]

Hi,

If you want to use xmonad from gnome-session-2.26, the correct way seems
to be to specify
# gconftool-2 -s /desktop/gnome/session/required_components/windowmanager xmonad --type string

This unfortunately has the effect that gnome-session waits a few seconds
for the window manger (now xmonad) to register via dbus, see
http://live.gnome.org/SessionManagement/GnomeSession

xmonad does not support the gnome-session protocol, but you can work
around the delay with this code in xmonad.hs

import XMonad
[...]
import System.Environment
import System.Cmd
[...]
main = do
	env <- getEnvironment
	case lookup "DESKTOP_AUTOSTART_ID" env of
	  Just id -> do
		rawSystem "dbus-send" ["--session","--print-reply=string","--dest=org.gnome.SessionManager","/org/gnome/SessionManager","org.gnome.SessionManager.RegisterClient","string:xmonad","string:"++id]
		return ()
	  Nothing -> return ()
	xmonad $ defaultConfig {
[...]      -- simple stuff
    }


I guess some stuff can be improved about this, such as using the DBus
package from hackage, but it’s a start.

Greetings,
Joachim
