X Display

[Thom Cornwell]

When running xnmgraph from cron it requires a DISPLAY to connect to. The cron job executes as long as some one is logged in on the DISPLAY console. If not logged in at the console the shell kicked offed by the cron waits until there is a log in on the DISPLAY console. Is there a way around this other than VNC?

Hi,

You could set up a virtual frame buffer using either Xvfb or install patch PHSS_23546 which support virtual frame buffers. Once this is set up, you can set the DISPLAY to server:0.

Hope this helps.

Hello Thom,

you could get the free (OpenSource) VNC from
http://www.orl.co.uk/vnc
(I know that you will be redirected to an AT&T site
in Edinburgh, but the old URL is shorter ;-)

Then install it on your HP box, create an "rc" script
to automatic start the VNC server on booting and
point your $DISPLAY to it:
export DISPLAY=$(hostname):1

Then you do not need anybody logged in...

HTH,
