Description Dalibor Pospíšil 2016-09-10 10:29:36 UTC 
Description of problem:
I have Lonevo x240 in dock with two external monitors which do not want to switch off, in gnome-shell it works.

If I use xset dpms force off, it works but after some time (a minute or earlier) it became on again.

Comment 1 Dalibor Pospíšil 2016-10-02 18:17:20 UTC 
It appears that it started to work. I don't know which particular component is responsible for this as mate-power-manager has not been updated. Can you advise me the component so I can confirm it?
Comment 2 Wolfgang Ulbrich 2016-10-03 05:06:57 UTC 
Not sure, maybe systemd, upower or the kernel.
