It's just a home-grown program that's started from .xsession.
It sets the X background colour in a loop, with excessive
temperatures taking priority over power indications.

It used to be written in shell, but I converted it to python
some years ago when I found that reading the files in
/sys/class/ could fail (3.x kernels). Python's try…except is
easier for me to code than shell's trap mechanism.

I wrote it originally for monitoring whether the AC power
was connected (the brick was unreliable), and the state of
the battery. Temperature came later, for the Dell laptop
I mentioned. That laptop was scrapped last year, and
ironically the Acer laptop it now runs on has a completely
broken power controller (it only runs with AC power).

Woefully underpowered to run even one browser, this Acer
fortunately has a good fan, so it doesn't run too hot. But
it does suffer from symptoms that are somewhat similar to
the OP's—sometimes you have to wait a minute or two (and
avoid touching the touchpad) for things to catch up. But
you can tell it's merely swapping heavily, because the
disk-active light stays lit. (Firefox on buster in ½GB
at 1.5GHz, encrypted /home and 1GB swap.)

Cheers,
David.
