aticonfig within crontab

[IanVaughan]

Hiya,

I'm trying to read some values from my AMD GPU via aticonfig within a script started via a crontab.

Its running under the superuser's cron (i.e. "sudo crontab -e)

* * * * * /home/ian/monitor.sh

(I've also tried :

* * * * * DISPLAY=:0 /home/ian/monitor.sh

The file its running is a exec, owned by root :

4 -rwxrwxr-x 1 root root 2645 Mar  1 21:22 monitor.sh

And looks like this :

#!/bin/bash
# monitor.sh

temp=`DISPLAY=:0 /usr/bin/aticonfig --odgt`
echo "$temp" >> /tmp/temp

Every minute I get the following in the output file :

ERROR - X needs to be running to perform AMD Overdrive(TM) commands

But when I manually run the script, it works fine.
i.e.. running "sudo ./monitor.sh" appends this to the output file

Default Adapter - AMD Radeon R9 290 Series
                  Sensor 0: Temperature - 80.00 C

I can't see/find what I'm missing, can anyone help me on this?

Many thanks in advanced.

I suspect you may be missing another environment variable that your X-based terminal has, but that the cron environment lacks.

Thanks, I could not for the life of me find out what was missing, I even used my profile from the script!

But I solved it by using my user crontab and not superuser! :sigh:
