More details:

you need a xorg.conf file, such as:

 https://src.fedoraproject.org/rpms/octave/blob/master/f/xorg.conf
 https://src.fedoraproject.org/rpms/octave/raw/master/f/xorg.conf

You want to run the non-setuid Xorg executable, on Fedora this is 
/usr/libexec/Xorg.

Then I do:

/usr/libexec/Xorg -noreset +extension GLX +extension RANDR +extension 
RENDER -logfile ./xorg.log -config ./xorg.conf :99 &
        
sleep 2
        
export DISPLAY=:99
        
the sleep is to give the server time to initialize.

HTH,
