I'm currently using Ubuntu 11.04 using the "Ubuntu Classic" session at login (Gnome 2). I recently tried xmonad as the window manager for the gnome session, and I like it when my laptop is plugged to a big monitor; I used the method outlined here
to get xmonad as the window manager and keep everything else gnome. When I don't have my laptop plugged in to another monitor, I prefer metacity due to the limitations on screen real estate.
Is it possible to create multiple two ubuntu classic sessions with each using a different window manager? If so, how? I am aware there is an xmonad session in itself, but this isn't what I want as I would like all the features from gnome to be kept. Please let me know how.
Or, please let me know if it's possible to change window manager inside a session without logging out. This would be even MORE useful.
