LinuxQuestions.org - Does anyone know a procedure for installing XVFB under RHEL5U2 64bit?

I have installed the following RPM xorg-x11-server-Xvfb-1.1.1-48.41.el5 (x86_64) but require the script to start xvfb with the right options. I used the following on a RHEL4 system ( just included the start function.) but the paths have changed under RHEL5 wrt the following line showing the rgb path
-co /usr/X11R6/lib/X11/rgb -fp unix/:7100

I can't seem to locate rgb as above. The other paths are fine as they are now at /usr/bin/Xvfb and /usr/lib64/xserver.

I certainly would appreciate a nudge in the right direction guys.

Thanks.

start() {
echo "Starting ${prog}..."
cd /var/tmp
nohup /usr/X11R6/bin/Xvfb :1 -screen 0 6x6x8 -pn \
-co /usr/X11R6/lib/X11/rgb -fp unix/:7100 \
-sp /etc/X11/xserver/SecurityPolicy -ac &
RETVAL=$?
sleep 1
ps -ef | grep Xvfb | grep -v grep
return $RETVAL
}
