Editing Xmonad/Using xmonad in Gnome (section)

===Ubuntu===

[See below for version-specific instructions]

I had tried above methods described by "simple hybrid", but they are not staight forward and didn't work.
<pre>
export WINDOW_MANAGER=/path to xmonad
gnome-sesson
</pre>
If once I execute "gnome-wm" manually, after that it works, I got xmonad integrated in gnome well. However, once I switch to my gnome session, and then return back to my xmonad session, the xmonad window manager isn't run, just as I log into the gnome session.

After delving into gnome-wm script and some analysis and many try, I found out why the plain script did not work. Because I had turned on the "auto save gnome session" function, I guess gnome-session wouldn't call gnome-wm again when I change from gnome session to xmonad session.
So I disable the save session function, and remove the files in <code>.config/gnome-session/saved-session/*</code>.

Finally it works! This indirectly prove the above guess is right.
Actually I had put this script to xmonad-custom.start, then I can have gnome and xmonad session seperated, and they don't interfere with the other. I think this method is simple yet elegant, and easy to understand.
