Re: Can't cron sct.

Hi,

many thanks to both of you for your replies.

I tried to pass DISPLAY env to cron without success: how is it done?

sctd is not a viable answer as it works just with fixed increments or
decrements; and from man sct:

 "sct samples the color ramp in interval steps of 500 with temp values
     between steps being interpolated."

So I doubt decrements of two every minute would guarantee white balance
quality...
