Screen blanking after 15~ minutes (already turned off settings in Power manage)

Hello,

Recently installed this build and really like it so far.

Having a persistent issue with the screen blanking (or going into hibernation, turning off my monitor) at about 15 minutes. I went to Power Management and turned off all of those so I am unsure where else this could be originating.

Welcome :slight_smile:

Check with htop your memory use,

and temperature.
Also check log files like

journalctl -b -1 | grep -i hibernation

All in all, I’m glad it runs on such a machine at all.

It runs pretty well aside from this although I don't do much heavier than DOSBox emulation.

Here is the output from the log, I also checked if other Hibernation/Sleeps were running. htop showed 1.2gb ram consumption.

I have edited your post.

It appears LXQt is currently allowing DPMS to override the user-specified settings in LXQt Power Management, the reason given being "lxqt-powermanagement should not silently touch other components settings". See the discussion here:

It looks like they are fixing this behavior so DPMS will be overridden when the "idleness watcher" is enabled, which seems reasonable to me. The issue is still open at the moment however, so in the meanwhile you may wish to employ the workaround mentioned in the issue (disable DPMS in a startup script).

A simple way to do this would be to make an .xprofile file, which SDDM will source when starting X11.

micro ~/.xprofile

Add to the file:

xset s off -dpms

Save and exit.

I hope that helps, welcome to the community @salsa. :slightly_smiling_face:

Yep, looks like that got it. Thank you!

if by any chance it all starts blanking again after a reboot, what i did was just add caffeiine-ng and add a couple of apps to preferences. No more blanking. Its in aur, so can be downloaded and installed locally if need be.

Just a brief correction: ~/.xprofile does not need to be executable, I took that part out of the post above. I'm not sure why I added that; it was late and must have been typing on auto-pilot. :sleepy:
