Note: Xfce Power Manager 4.16.0
I upgraded the system and the default setting has screen lock enabled. After online searching I found out this feature is accessed through the power manager. I have tried to start the power manager both through the control panel and from the command line and it will not run. This is not a laptop so power management is not that important. I want to disable screen locking entirely and it would also be good if I could make the power manager work, but getting rid of screen locking is more important.
I have done more experiments and the problem does not seem to be with the screen saver. It can go into screen saver mode and then turn on the monitor and everything is fine. However if it waits longer I have to reboot. This implies it is trying to go into another power saving mode beyond screen saving. Considering this is an old HP Z210 workstation that may not be possible.
Also, when I launch the xfce4 power manager I can see it on the task display but it never puts up the UI and after a period of time it quits. The command is “xfce4-power-manager-settings” with no command line args. When I run the program from the command line the result is the same.
I still need to solve the problem. Is there a file I can edited to change the power saving settings? Is the power manager the only program that affects this operation?
Thanks.
I tried running xfce4-power-manager from the command line with the -c option, which theoretically should start configuration and I got the following output:

I had to stop it with control-c
