What's turning off my display?

[pizza-rat]

Had this issue since I upgraded my PC, at first I thought it was my graphics card failing til I realized it happened after the same amount of elapsed time idle every time.
On a relatively fresh install, what is it that's doing power management on my display? I've been lazy and just used xfce4-powermanager as a stopgap, because its settings seem to override whatever's doing this, but I'm curious if I can disable it without needing a power management program.

It's not just my monitor itself because I noticed it first while playing stuff on PCSX2, and when the screen would blank, the audio would hang/repeat as well.

You need

You can change screensaver's settings with xset.
Things that can result in display going off are enabled blanking, suspend and dpms.

Hmm, I do have the DPMS line in my xorg.conf, perhaps that's it. Should I remove the line or perhaps just set it to off with xset in my .xinitrc? xset -q also tells me prefer-blanking is "yes" and the cycle is "600" which, if that means 10 minutes, checks out.

You have xorg.conf? I don't think many people use it anymore, it's hardly ever necessary those days.
Anyway, yeah, xset s noblank and xset -dpms should do the trick. This change is runtime-only, restarting xorg will reset to default (unless your DE remembers it upon logout and restores later, I think e.g. gnome does that)

Yeah, I think I needed one to set my monitor order or something. Don't think you need it if you use a DE but I usually use openbox or icewm.

Anywho, I put "xset s off -dpms" in my autostart file and I think it'd taken care of it! Thanks!
