Well, you know how X runs on tty7, is it possible to get another one to also run at the same time on tty8?

The first will usually run on display 0 so for the second type:
startx -- :1
and the third
startx -- :2
etc.....

Wow I never knew you could do that, you learn something new everyday.

Might not be relevant now, but you could also nest them ( Xserver as a windowed app within an Xserver ) using Xnest . ( man 1 Xnest )

Just out of pure curiosity:
What would happen (or rather, how would you choose) if you opened enough X's that you ran out of Fkeys. So, after CTRL ALT F12, where would you go?

Cool

Funny, I tried it the day I learned about the possiblities that multiple displays offered. My conclusion was that you can open as many as you want, but cant get to the seventh and successive once you switch consoles.

Thanks... another "just out of curiosity" question to add:
If I startx on those different tty's, can I send them out to different displays (I'm assuming so, this would be a good reason to have that option)? If so, how? This assumes multiple displays, even if they are over a network.

Thanks for the info so far!

Cool

Dear its linux

This is nice.. And not only you could use many X but if you have any of them online, they are all online.. THis is great, now i could use one with KDE menu and the other one with GNOME..

sure, why not. You can export the DISPLAY variable on the shell from which you launch the x app ( client); lets say xeyes. You want the xeyes to be served by the x server running at a different box running at vt 8 ( Ctrl + Shift + F8 ) and having display number 2.

export DISPLAY=<xserverip>:2
xeyes

or for a one time thing..
xeyes -display <serverip>:2

ohh. this assumes you have started x without --no-listen tcp and you have proper authentication in terms of xhost or MIT-MAGIC-COOKIEs. Otherwise the server will refuse the connection.

yup, kde and gnome are just a bunch of X client apps including a window manager for each. You can run as many different window managers as you want as you have X servers.

omg, this kicks arse!! w00t, now i can run Games on one X session, while surf on the other, and 'alt tab' so to speak between the two quite easily

/me bows down to startx -- :2

Sure does. I dont play too many games so there must be some reason I can't see now that make me want to ask if you _really_ need multiple X servers for what gaming/surfing. Cant one use multiple workspaces?

I was thinking something, does running too many X servers take RAM space in some way? Or the RAM focus on the one you are using at the time and the other just are taken care by the virtual memory/swap partition, I don't know if I make any sence.. But any ideas?

Of course loading an extra X server is going to take up RAM and CPU cycles, shouldn't be two much tho is there isn't a heavily active process running on the other server. Use 'top' to find out what exactly is happening.
