I have a set of startup scripts which start the server by running some commands as
root, others under a user account. The script which starts vfxb does the following:
XVFBIN="/usr/X11R6/bin/Xvfb :1 -screen 1 640x480x24"
DISPLAY="localhost:1.1"
export DISPLAY
$XVFBIN &
/usr/openwin/bin/xhost + localhost
Again, this is run as root. Then the script sets up other appropriate variables and
calls:
( su - www ; $TOMCAT_BIN $TOMCAT_ARGS )
This is on Solaris 7, but should be the same. I guess the main points are:
- I use localhost:1.1 to avoid conflict if I want to run a real X server for use on
the console (0.0)
- I set and export the DISPLAY environment variable.
