    Default Monitors won't sleep. DPMS reset to 0 every minute

    Running Gnome.

    This is an aggravating issue. Just upgraded from 42.3 to 15.0. Everything is working except for power management. My monitors simply won't go to sleep. I have Settings->Power->Blank Screen set to 5 minutes, and the monitors aren't blanking. I run xset -q, and it shows:

    DPMS (Energy Star):
    Standby: 0 Suspend: 0 Off: 0
    DPMS is Enabled
    Monitor is On
    So I run xset dpms 300 600, and they never go into sleep mode. I check xset -q again, and they are reset to 0. As a test, I ran xset dpms 10 20. The monitor goes to sleep as expected after 10 seconds. However, after about a minute, xset shows DPMS set back to 0 0.

    I have no idea what process keep resetting these. Where should I look?

    I had similar issue (using KDE). My solution was to turn-off screen saving (blank screen) and use only suspend as power saving option. Whish is ok for me
