Hey,
I have pretty minimal i3wm install and I recently tried to set up blanking and DPMS, but the thing is it does not work:
$ xset s blank s 10 dpms 10 15 20
$ xset q
Keyboard Control:
auto repeat: on key click percent: 0 LED mask: 00000002
XKB indicators:
00: Caps Lock: off 01: Num Lock: on 02: Scroll Lock: off
03: Compose: off 04: Kana: off 05: Sleep: off
06: Suspend: off 07: Mute: off 08: Misc: off
09: Mail: off 10: Charging: off 11: Shift Lock: off
12: Group 2: off 13: Mouse Keys: off
auto repeat delay: 660 repeat rate: 25
auto repeating keys: 00ffffffdffffbbf

fff7ffffffffffff
bell percent: 0 bell pitch: 400 bell duration: 100
Pointer Control:
acceleration: 2/1 threshold: 4
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 10 cycle: 600
Colors:
default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff
Font Path:

DPMS (Energy Star):
Standby: 10 Suspend: 15 Off: 20
DPMS is Enabled
Monitor is On
What could prevent blanking and suspend from happening and how to debug this? I don't have any screensaver installed, could this be an issue?
