xfvb at system startup

[polani]

We are trying to start vfb at boot up (using inittab) which is not
working, but
when same script is executed from prompt, it works fine. Script is:

"Inittab entry"
"
svfb:2:wait:sh /localscripts/startvfb >/dev/console 2>&1 # start vfb "

Script:
"
#!/bin/ksh

# Start X Virtual Frame Buffer (xvfb) for Oracle IAS

/bin/nohup xinit -- -vfb -force :1 1>/dev/null 2>/dev/null &
"

In this manner vfb is not working and ps entry is as follows:
"
$ ps -eaf | grep -y 'vfb'
root 250010 266422 0 08:04:42 - 0:00 X :1 -vfb -force :1
root 266422 1 0 08:04:42 - 0:00 xinit -- -vfb -force :1
"

When this process is killed and 'startvfb' script is executed from prompt,
it
works fine and 'ps' entry is as follows:

"
$ ps -eaf | grep -y 'vfb'
root 254144 675948 0 10:33:03 - 0:00 ksh
/usr/lpp/X11/defaults/xserv
errc -vfb -force :1
root 675948 1 0 10:33:03 - 0:00 xinit -- -vfb -force :1
root 692358 254144 0 10:33:03 - 0:00 /usr/lpp/X11/bin/X -D
/usr/lib/
X11/rgb -vfb -force :1
"

Kindly advise why this difference in process entries when starting from
inittab
and how can this be resovled?

You need it to be respawn not wait in the inittab.

I have always set this in the inittab:
xvfb:2:respawn:/usr/bin/X11/X -force -vfb -x abx -x dbe -x GLX :n > /dev/null

And for the 1>/dev/null 2>/dev/null can be changed to: ‘>/dev/null 2>&1’ which is less typing and more standard.

Maybe you need to start both the window manager and the X server which is what xinit does.
