Hi,
I have a problem which (I guess) is probably related to this very recent one.
I run Arch Linux with MATE and LightDM.
After a recent update I lost the functionality of the brightness adjustment keys (as it happened in the post above). Moreover, I lost the power-manager applet icon in the notification area, and I can't figure out how to get it back. This seems to be quite common to anybody with the same distro (including Antergos, basically the same) and desktop installed.
Any solution?

Same problem here. Doing a
journalctl -xb I've noticed that the process mate-power manager core dumped
Process 3649 (mate-power-mana) of user 1000 dumped core.right now I cannot investigate more, but if you find it useful this is the output of my core dump:
systemd-coredump[3742]: Process 3649 (mate-power-mana) of user 1000 dumped core.

Great! It works at startup as well. Thanks
EDIT: I marked the thread solved 5 mins ago, but have just noticed that it stops working after some random time.

The problem still wasn't fixed, as what I posted was a temporarily fix. Everytime the system starts, mate-power manager fails, and we don't know why yet.
The problem seems to be related to this, as it crashes when keyboard backlight is changed.
