Dual X servers?

[Peter Arremann]

Hi,

has anyone on this list managed to run two X servers on one system? I repaired 
the backlight on an older 17" display and hooked it up to a PCI ATI card. I'm 
running to 20.1" flatpanels in xinerama mode as my primary display and I 
don't want to add the 17" into the xinerama setup. Instead I would like to 
run a separate X server so I can have logfiles and stuff scrolling by on the 
small display and use the larger ones for work. 

Of course I would like to use the same mouse and keyboard on both displays but 
that's not going to work out I guess - so I installed a USB mouse and 
keyboard. I mocked around with my xorg.conf to make the new entries and while 
I use startx to run the xinerama setup I run  "X -layout Addl :1" for the 17" 
one. Unfortunatenly as soon as the second X server comes up, the first one 
suspends - when I kill the second display, the xinerama one immediately comes 
back...

Any ideas?

And yes - I got nothing better to do on a Saturday evening - my gf is visiting 
her family :-)
