I swtitched from OpenRC to systemd which was surprsingly painless. :o The only serious problem I have now ist that the DPMS of the monitor stopped working properly.

In MATE power management screenblanking time is set to 5 minutes. After that, the monitor gets switched off, as it should. but after a short time it is switched on again! When in an XFCE session the screen goes black, but never reaches 'DPMS off' state, the monitor stays switched on. I am running gentoo-sources-4.0.7, XFCE 4.12, MATE 1.10 (from open-overlay).

Any ideas what could couse the problem?

unsupported because overlays.

overlay software tend to have "issues".

Hardware or Software issue.
when the monitor works as of now with another distro on the same computer without changing the hardware ti is software based.

and no idea how many systemd users here use "your" desctop environments, and how many use overlay based DE ... I doubt many, and so I think you just run into a bug and should report it there. to the maintainer of the overlay.

xfce-base/xfce4-meta-4.12 is not in an overlay, it's stable. As sys-apps/systemd-218-r3 is.
Only MATE 1.10 is in an overlay.

I agree.
So that's why I was testing if this behaviour shows up in another Desktop Environment too. Unfortunately it does. Both, xfce-power-manager and mate-power-manager have the same problem here.

I simply thought it would be a good idea to ask here first, if some people have experienced similar problems because I ran out of ideas after some research. If I get no input, and can't solve the problem after some more research, I will of course file a bug.

Mkay, this seems a more general issue...

Even if force the monitor off via
Code:
xset dpms force off
it turns back on again after a few seconds. And even if there is no xfce4-power-manager or mate-power-manager running...

On the other hand xset q shows nothing suspicious.

ef@supah ~ $ xset q

I wonder if you ever figured out what this issue is.

I have the same issue with xfce4 + openrc.

At first dpms will work, and then at 'some' random point, it stops working anymore and the screensaver will remain on 'forever' (I've left it overnight).

Even once dpms has stopped 'working' automatically, I can still call xset dpms force off and this works.

I'll wait now for tonight and see if forcing it manually first has some how fixed the issue but I doubt it.

Code:
tim@MushaV3 ~ $ xset -q
