Hi, Currently I have set up my installation of ArchLinux to auto-login two users on two different virtual consoles, starting one X server each. One X server runs Xmonad and the other one runs Gnome. This way it's possible to switch between the the two users' desktops with Ctrl-Alt-F1/F2. It works quite nicely, apart from the fact that virtual console switching is a bit slow. That could maybe change in the future, with kernel mode setting etc. However, I am pondering a different setup, where I only start one Xserver running Xmonad. Then I would let that instance of Xmonad start two instances of Xephyr (a nested X server), one that runs another instance of Xmonad and one that runs Gnome. I could switch between the users's desktops by appropriate key bindings in the bottom Xmonad instance. The first Xmonad instance would run as a separate user, or maybe the root user. I can see several advantages with this approach; faster user switching, global key actions configurable in Haskell, global Xmobar panel. Do you think this is a feasible setup? Is Xmonad lightweight enough for this configuration? Can the key bindings in the two Xmonad instances be coordinated easily (can I somehow create a "clean" configuration in the root Xmonad, removing all defaults and just add a few global key bindings)? Or do you think it would just become one big mess? :) Regards, Rickard Nilsson
