Hi,
I have fedora35 installed on my desktop with a Radeon RX 570 driving
three monitors, with the Cinnamon desktop, although it could be the
other variation of Cinnamon that's available by default - I checked
the Settings menu and can't find any way to determine which it is. I'd
like all three monitors to turn off after 15 minutes of inactivity.
What is the best way to do that? Simple question, but clearly not a
simple answer.
I'm an old-school admin from a time when we had to build our own X11
config files. I just expect things to work now, so I haven't really
kept up with the desktop, even though fedora and whatever graphical
display it provides by default has been my primary desktop since
before Windows XP.
Now, when I set the "turn off the screen when inactive for" option to
5m in the Power Management settings, I find that it takes far longer
than five minutes for it to actually turn off the monitors, but then
not only do they all immediately turn back on, but all of the windows
on the middle monitor are shifted to the two left and right monitors.
wtf? It's incredibly frustrating to have to reposition all windows
back to their original location.
How do I troubleshoot this?
