[lug] xv with cron and sc_reen_sa_ver

[Gary Hodges]

Sorry for the late replies to my xv/screensaver posts.  I think the NOAA 
mail filters were purging my original post and the replies because of 
the word "screensaver" in the subject.   We'll see if this gets through  
with my munging of the subject...

It sounds like something fundamental has changed with the X display.  
I'll look into the "magic cookie" concept.   :-) 

On Stimits reply...  The xv stuff is running from my cron job, and the 
screensaver is running on my X session so that should be OK, right?  I 
did try your xhost suggestion but it didn't work.  I'll play around some 
more and report back if I get it going.

Cheers,
