xfce4-power-manager error when additional monitors connected

Hello everyone,

I have lenovo P15 laptop with NVIDIA Quadro T1000 GPU and two monitors Philips PHL278E1 connected by Display Ports (DP).
Before the last week this configuration worked properly, however last week after the system update I faced with problem: xfce4-power-manager don't start if monitors connected to DP.

When I try to start it from command line - I see next message:

$ xfce4-power-manager

** (xfce4-power-manager:2570): WARNING **: 11:27:04.249: Failed to get name owner: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Could not get owner of name 'org.freedesktop.PowerManagement': no such name

Segmentation fault (core dumped)

I've tried to start mate-power-manager - also had an error, so it looks like it isn't xfce4-power-manager problem.

If I disconnect monitors from DP - and reboot the system - xfce4-power-manager starts properly and it's possible to connect monitors after that. - So the problem occur only if the monitors connected to DPs during system rebooting (even if monitors turned off and/or powered off).

It is still possible to unplug it from DP manually and plug it back every time when I update the Arch or reboot the system. However, I would like to fix it correctly.

I would really appreciate your help.

Thank you in advance.

Re: xfce4-power-manager error when additional monitors connected

The problem was resolved by installation of mesa-utils:

pacman -S mesa-utils
reboot

However, it lead to another problems, see description here:
https://gitlab.freedesktop.org/upower/u … issues/126
and here:
https://gitlab.freedesktop.org/upower/u … issues/177 (this is pretty fresh)
Still the problem for Kernel Linux 5.19.4-arch1-1 x86_64

Re: xfce4-power-manager error when additional monitors connected

Finally the problem was resolved by last update to Kernel Linux 5.19.5-arch1- x86_64
