How to start a second X11 display from within X ?

For a game i am playing (freespace2 open) i would like to run it on a second X11 virtual display.

Following Fs2_open_on_Linux#fs2_open_freezes_X i am able to start second display with xinit -- :1 , but this only works from console.

Also the method used there (copying the mit-magic-cookie) doesn't appear to be very user-friendly.

So i have 2 questions :

is there a way to give a user permanent permission to start a second display ?

can starting a second display be done from within X ?

This may not be much help to you, but 'xinit -- :1' works on my computer (within KDE).

With qingy (in AUR), you can start several X session.

What DE or wm are you using, kde has an inbuilt option to start another session

You might like to try this http://www.kde-apps.org/content/show.ph … 2d72c58e8c

It's just something I made to learn how to use kommander. (you need kommander installed)
It's just a GUI for starting new X-servers and running programs on them.  Currently you can only run one program at a time but that's probably OK for a game

Re: How to start a second X11 display from within X ?

I've checked and the change to xauth appears to be permanent as it was still present after a reboot and a cold start.

I use KDE as wm/de , but start it from console with startx.
I have no options for starting another session, possibly because i don't use kdm or another login manager.

startx works from within kde , xinit works from console.
Unfortunately fs2_open crashes with a segfault after switching back and forth between display 0 and display 1 a few times.
When running fs_open on display 0 it never crashes.
Sofar i've used startx -- :1 , xinit -- :1 and xinit /usr/bin/fs2-open -- :1 , and they all give the same problem.

Thanks for the tips, i'll check them out.

Re: How to start a second X11 display from within X ?

interesting, i didn't know that you can start another X server...
if i do xinit --:1 i get a "Server is already active for display 0..."
so would it be possible to start an X server with tv-out enabled from within a x server that doesn't have tv-out enabled ???

If you using kde, you could make life alot easier if you need multiple xsession by running kdm...

I mean my system boots 21 second including starting KDM starting from xinittab... if I add it as a deamon in rc.conf it takes 36 seconds
