Using DPMS, my screen goes blank after 10 minutes. How would I go about dimming (lowering the backlight) of the screen a few seconds before this happens, as a sort of warning?

Output of xset -q:

[...]
Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  600    cycle:  600
[...]
DPMS (Energy Star):
  Standby: 600    Suspend: 600    Off: 600
  DPMS is Enabled
  Monitor is On

Dimming is done by screensavers (that will also do the blanking without the need for X11 automatically timed DPMS features). Try the configuration options of xscreensaver or gnome-screensaver or whatever locking program comes with your Desktop (which window manager is it?). Your window manager may also have this interface in its "Power" (or similar) options.

  • Thank you for the answer! I'm running bspwm, so most of my configuration is manual. I've given xscreensaver a go, and it seems to be working perfectly. – Birjolaxew Apr 9 '17 at 21:37
