Want to run multiple X server sessions on the same computer?

[mhelios]

Just came across a cool way to run two or more X sessions with GNOME/KDE and GDM on the same computer.

Firstly, there are many ways to accomplish this; one of the simplest being to switch to VT[1-6] and running `startx -- :1`. However, by default, the startx script will load the very minimal TWM environment which is probably not what most people want.

There's a handy program gdmflexiserver (Thx to Alexander Dalloz for pointing this out) that when run will save the state of your current X session, load the GDM login screen where you can then login as another user concurrently with the original X session. This X server will run on VT8 (or VT9 etc for more X sessions).
Once logged into GNOME as the other user, you can use the key-combo Ctrl + Alt + F7 to return to your previous X session and similarly Ctrl + Alt + F8 to get back to the new X session.
When you decide you want to get out of this secondary X session, just select Log Out from the menu and the X server will be killed and you'll return to the original session.

Just run /usr/bin/gdmflexiserver as regular user on the command-line and you're done! :)

How about normally logging into Gnome (for instance), then switching to VT1, logging in text mode, and then starting a KDE session (under X :1), such that you would have both Gnome and KDE running? :)

When I try to run gdmflexiserver from a terminal within Gnome, xscreensaver is activated, the screen flashes a couple of times, a 'wait cursor' appears briefly, the screen flashes a couple more times and then goes blank. If I press a key or move the mouse, I'm returned to my original X session with xscreensaver prompting me for my password.

Any suggestions? Thanks.

how about going to applications->system tools->new login

:cool:

p.s. its hidden by default, just right click the menu, edit menus, check the New Login under system tools and it will appear

I'm not sure if you're being facetious or not, but what do you think applications->system tools->new login runs?

Thanks, I wondered where that option went.

I assume it runs the app that you were mentioning?

from the terminal, you should be able to run:

startx -- :1

to get a second X session running as whichever user executed the above command.
