Re: xset +dpms is not controlling monitor powerdown on raspberry pi 3b
I doubt xscreensaver is any default, KDE and probably Gnome have their
own forks of it because it doesn't get along with their stuff. Some
of the neatest screensavers need OpenGL, there are about 200 different
ones, it's been around at least 20 years. It's a framework that brings
up contributed programs when desired then closes them. It's a big
deal.
In the Pi environment where the GPU is the boss and the CPU runs under
it, having a program like tvservice that controls the GPU can be
useful. 2 of my 3 monitors are too old for the fancy EDID stuff to
work, so I still don't have quite the video modes I'd like. This
monitor I'm using has a max resolution of 1280x1024 but I'm running at
102x768 because the 1280x1024 blanks out once every couple minutes,
there's something in the timing a tiny bit off. The Pi can also do CVT
(Consolidated Video Timing), a little like modelines. Modelines and
xvidtune probably don't work.
So does this Pi run a milling machine or something? I think there are
keyboards like modern phones that have no "keys", they're capacitive
pads under a flat glass or plastic cover so nothing can get into them.
The only machine tools I've run were several decades too old to have
computers. Good to learn on, but totally manual.
