Debian 10 with linuxcnc 2.9 goes to sleep after 10 minutes. How to stop?

  Hello everyone, I have a configuration issue.  If I let this install sit with no activity the screen goes blank.  When I hit a key it comes back up but it's at the login screen not the desktop with QTplasmac sim running.
 I went into the /etc/systemd/sleep.conf file and changed all the AllowSuspend options to "no" and still have this issue.
 What other options are there??

put this in your .bashrc script
xset s off
xset s noblank
xset -dpms


OR you can type in the three lines on a terminal

Then run xset q      to see if it took

 

I believe this might be window manager dependent. I use xfce.

So I did the following
sudo nano /home/plasma/.bashrc

At the end of the file I added this
# setting to stop screen from going to sleep
xset s off
xset s noblank
xset -dpms

And .... didn't fix the problem...

What does xset q spit?
 

Interesting.... It hasn't gone to sleep on this second reboot.

xset q....... Screen saver prefer blanking: no, DPMS is disabled.

Looks like it took finally.

And it's back to sleeping every 10 minutes.

This is weird, was working one time.
Is there a desktop power setting like in windows?

What does xset q show? If it shows it is disabled then something else is blanking the screen.
The scripts start it on machine boot so, if you dont have it in something like a bash script on l;ogin, it will be on again.

Check BIOS, there are settings there for turning off the screen and other stuff on older PC's.
