Hello Tyler,
>2. Gave permission to connect to the Xserver from localhost: xhost +
>localhost
Here I wrote to the terminal:
xhost + localhost (check the man pages for more info on the xhost command)
>3. started the Xserver with DISPLAY 0 as an ordinary user
Here I started by setting the environment variable DISPLAY to 0:0 (export
DISPLAY="0:0" .note that you probably have to do this before you run the
xhost command).
then I simply ran startx.
Make sure that your DISPLAY variable is set to "0:0" on the console from
where you run the script that starts the JServ. Also make sure that you run
startx and the JServ startup script as the same user. Also, it does not
work unless you are logged directly on to the host. I tried doing it
through telnet and it didn't work.
This is what solved this problem for me but there are probably some better
solutions out there that don't require you to start the JServ manually!
Hope this will be of use,
Regards,
Ásta
