"Put display to sleep" timeout ignored #342

Open dark-penguin opened 4 years ago

dark-penguin commented 4 years ago

Expected behaviour

I set "Put display to sleep when inactive for:" to 30 minutes. Monitor turns off after 30 minutes.

Actual behaviour

I set "Put display to sleep when inactive for:" to anything. Monitor turns off after 10 minutes.

Steps to reproduce the behaviour

Set "Put display to sleep when inactive for:" to anything (I have not tried "Never" though). Monitor will turn off after 10 minutes.

MATE general version

1.20.4

Package version

1.20.3-2

Linux Distribution

Debian Buster

Does anyone care about bugs in Debian stable?..

This might be a problem with something else, but I have no idea how to debug it further.

I also set the "Screensaver" timeout ("Regard the computer as idle after:") to the same time, but disable both checkboxes ("Activate screensaver when computer is idle" and "Lock screen when screensaver is active").

UPDATE: Tried to confirm this on Debian Live in virtualbox. I've set both DPMS and screensaver to one minute. Nothing happened, no matter how long I waited, regardless of whether the screensaver is enabled or disabled. Maybe virtualbox does not support DPMS, but this time even the screensaver does not work, which probably means those timeouts are completely ignored, and instead governed by something else - something we can't configure (so it's either "never" on new systemd or 10min on my system).

I can confirm all of this except the time, which I've never measured.
