Disabling screen saver

As it is a touchscreen this is bad, because there is no way to tell what button I am going to hit when I randomly touch to turn the screen back on.

Had the same problem

command line for turn off the power management system AND the screensaver
but still need to do it every startup.

wrote an executable file pms.sh at home directory and add it to >System>Preference>Startup Application

make the file executable with
I reckon this literally disable the ACPI.

"The deal" is the fact that disabling the screen blank is an issue.

I have set both the power management and the screensaver settings numerous ways and still get a blank screen in 10 minutes.

I've disabled them, I've set them to an hour, to 10 hours and every which way. No difference. Obviously there's yet another place it's being controlled.

Have you tried linuxcnc.org/index.php/english/forum/18-...r?limitstart=0#55601

Not yet. But when a user posted "what's the big deal, just change the screensaver" I felt compelled to answer him -- the screensaver parms are not effective.

I need to do some research on what else is affected by this "dpms" setting. A guy named Steve Rosenberg posted on his blog the following suggestion:

sleep 200
xset dpms 0 0 0
exit 0

He suggests the sleep is needed (at boot) because other parts of xfce seemed to change his settings later in the boot sequence. But he found that setting them after a delay worked. I haven't looked into any of it yet.

I also found this: wiki.archlinux.org/index.php/Display_Power_Management_Signaling . It's interesting that it states "Warning: XScreenSaver and xfce4-power-manager use their own DPMS settings and override xset configuration".

It's not the end of the world, it's just annoying.

That is why setting it from the LinuxCNC INI file is a good idea.

It's a lot worse than annoying when you only have a touch-screen to wake the machine up again and don't know what you are going to hit..

Is it possible to set in the linuxcnc.ini file, or is that a wish?

Dewey showed how to do it in the INI file here:
