[IDV #AKQ-639460]: isl script not working today, worked yesterday - X server?

Brian,

The IDV needs a "screen" (virtual or otherwise) to display to. I don't have much
experience working with Xvfb.

Googling around, I found this old post on this topic

http://www.unidata.ucar.edu/mailing_lists/archives/idvusers/2010/msg00002.html

Some the information therein is irrelevant so you will have to separate the
wheat from the chaff.

So it looks like you will have to download and install Xvfb on the host system
in question.

Then you start it with

Xvfb :9 -screen 0 1280x1280x24 &

As explained, you should be able to find that process in the process table.

Then, theoretically, you should be able to run your ISL script from cron.

I am curious to know the result of this exercise.

Best,

Unidata IDV Support
