I have a configuration with 3 monitors, 1 of them is disabled.
At the beginning whenever I left the workstation the monitors turned in standby automatically.
Now, don't know why, not anymore.
I tried to use the built-in xfce4-power-manager but it seems not working even if I change settings.
xset q output is:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff
DPMS (Energy Star):
Standby: 120 Suspend: 0 Off: 360
DPMS is Enabled
Monitor is On
I also tried to execute
xset dpms force standby and it works. But as soon as the displays go standby everything go up and running again (asking me for password ofc).
So I though that there is some app preventing dpms to work maybe?
Also, values from
xset q of the dpms are different from the values of the power manager
