I had a simple Qt program, when running, it shows a simple window with a countdown timer. If you might be interested in the code, please see here.
I had crontab line
* * * * * /home/my-user-name/Documents/bin/program
When executing the comment
/home/my-user-name/Documents/bin/program, the program runs correctly. But it's not invoked by the
cron. I have multiple cron jobs, all run smoothly except this one.
My question is:
Do you have any idea what might cause this? Qt problem?
I have searched around for
cron, and tried almost all the tips.
