Why can't I open another Xserver on VT7 to 8 in Fedora 10 to start a remote x session
 

Hi All,

It's been a long time since I have tried this on a Fedora box but it worked perfectly on my RHEL5 box.

Here is the process I followed,

X :1.0 vt8 2>&1 > /dev/null & # opens the Xserver on vt8 (ctrl + Alt +f8)

xauth list # Lists xauth entries and keys

xauth add hostname/unix:1 . HEX VALUE RESULTS FROM Xauth list command for
your hostname
i.e xauth add Ouroboros/unix:1 . 05d810832 etc etc
# adds authorisation for host on server using key

xterm -display :1.0 & # open xterm on display 1 - you can now ssh and start
a session i.e gnome-session


Now I am trying to do this on my Fedora 10 laptop to try and start another Xserver to have a full remote gnome session on a test box, but once I run
X :1.0 vt8 2>&1 > /dev/null & - I cannot get back to vt1 and my own session and the system appears to hang with no errors, I cannot even restart X with ctrl alt and bkspace. When I reboot there are no errors! it just seems to hang fully...

Does anyone have any idea's?

I think it's because the xserver will only allow one active connection. Can you try using vnc over ssh or some such?

Thanks for the reply, Any ideas why this may have been limited and if I can unlimit it?. I don't remember reading anything about it myself.

I always found it to be a great solution to run another xserver on a spare VT and use it to pump a full ssh Xsession from a remote server - I remember in one of my old contracts I used to support a number of SUN and Redhat boxes from my Fedora 7 or 8 machine and used to have their connections from VT8 to 12 - and even the full desktop's when I wanted or I had to show the DBA's anything!

Just another thought, why would it kill my system so badly, When I run the first command the VT does change to 8 and I can see the Xserver start (all grey with mouse) - then I try to change back to VT1 to run the next command but I get a blank screen and then cannot change back to any other terminal VT1 to 8 I just get a blank screen and no form of exit works.

I'm not sure exactly why this won't work, but I do know that the xserver in Fedora 10 is similar to the one in ubuntu 8.10, and they both have this type of problem.
