Thanks for checking that out.

Then it would seem (?) that it is not a [slim] thing.

I wonder if this same thing happens with a 'different' desktop or if
it is an XFCE-only thing.

Years ago, the first time I used XFCE (Devuan Jesse / ascii?) in my
WS I had power management issues so I purged any and all XFCE power
manager plugins and *.conf files.

BTW: is any box checked in your [Session and Startup] -> [General]
tab?

Best,
