You are most welcome, glad you enjoyed it. I am sure you can adapt it for a variety of needs ...

ssh -X comes to mind.

hey, is it possible to edit the script to add like (if I wanted) 15 different X sessions? ie: KDE4, blackbox etc...

and if so, how?

15

well, first you are limited to 6 by the default settings.

Other then that go for it

X sessions are numbered starting with 0

startx -- :0

then comes 1 , 2 , 3 ... up to 14

so

startx /path/window_mananger_1 -- :0
startx /path/window_manager_2 -- :1
...
startx /path/window_manager_15 -- :14

Now you can number your x sessions any way you wish (yo do not need to start with 0 and go to 14), up to 99

thanks, much appreciated

bodhi.zazen, thanks for the VirtualX script!
I'm running into a problem, however.

When I run it from the gnome session (and select gnome), the screen goes black for a moment, and then I'm popped back to the gnome session.

When I run it from tty1 (and select gnome), I get the grey mosaic pattern and the X cursor. No usual gnome session. None of the mouse buttons do anything. I pressed Ctrl-Alt-Backspace, and was sent back to tty1.

Okay, confession #1: I use fvwm as my window manager instead of metacity.

Confession #2: I don't have xscreensaver or numlockx installed, so I commented out those lines.

Here is the slight change I made to the script:

% diff ~/bin/virtualX-orig /usr/local/bin/virtualX
64,65c64,65
< 		DISPLAY=:2.0 /usr/bin/xscreensaver &
< 		DISPLAY=:2.0 /usr/bin/numlockx on &
---
> #		DISPLAY=:2.0 /usr/bin/xscreensaver &
> #		DISPLAY=:2.0 /usr/bin/numlockx on &
73c73
< 		/usr/bin/startx /usr/bin/gnome-session -- :2 2> /dev/null &
---
> 		/usr/bin/startx /usr/bin/gnome-session -- :2 2> $HOME/.virtualX-errors &

And here is what I found in .virtualX-errors:

xauth:  creating new authority file /home/shark/.serverauth.8154

I have installed dialog, and have edited /etc/X11/Xwrapper.config per your instructions.
Any idea where I'm going wrong?
