[SOLVED] Weird DPMS problem

Hey guys!

Ive been an Arch user for a long time, but I decided to give Manjaro a go on my new build, and so far I really like it. I've managed to get my setup exactly as I want it, with one niggling problem.

I'm running xfce with a dual monitor setup. I've disabled lighDM so I can boot to command line, and I've installed xfce4-screensaver so I can lock my screen. I've set the screen saver to activate after 55 mins, and (in the power manager) DPMS sleep to occur after 60 mins. The screen saver activates as expected, but it's 50/50 as to whether it then sets the monitors to standby 5 mins later.

If I force standby with the command

xset dpms force standby

I see the same issue! sometimes it goes into standby, sometimes it goes into the screen saver.

This is weird......any ideas!

here are my display options:

Keyboard Control:
  auto repeat:  on    key click percent:  0    LED mask:  00000000
  XKB indicators:

    09: Mail:        off    10: Charging:    off    11: Shift Lock:  off
    12: Group 2:     off    13: Mouse Keys:  off

  default colormap:  0x20    BlackPixel:  0x0    WhitePixel:  0xffffff
Font Path:
DPMS (Energy Star):
  Standby: 3600    Suspend: 0    Off: 0
  DPMS is Enabled
  Monitor is On

browsing the forums, I've just seen this Steam screws up suspend

possibly related....manually suspend does seem to be working now I've shutdown the steam client

Hey, thanks for linking to my post. This seems to be the exact same issue I am having.

Honestly, XFCE has had many power management problems since 4.14, so I've switched to Cinnamon. But if this is a Manjaro-specific problem, this should really be looked at.

After a bit of messing about checking stuff, I think it was definitely Steam causing my issues. This issue is resolved for me.

Thanks for your help CheeseEBoi!

No problem, but this is likely an issue with how XFCE deals with power management... I might report this but I don't really have much knowledge on the subject.
