Is ANYONE using separate X screens?

Interesting. I will try LXDE again and see where I end up.

4-some other X session on right display, simultaneously with first session on left display?
5-Other?

Having two different X sessions at once here on Fedora is working, but whichever session is has been switched to using Ctrl-Alt-Fn is using both displays, while the not visible other is apparently not responding to mouse or keyboard events:

Previously, I had one Xsession, only one instance of Xorg. I don't mind if I have to have 2 Xorgs running, as long as it works. In the past, one Xsession carried both without issues. As previously mentioned, I will just swith to XFCE adn see if that works for me. I really only need to run MythTV or Kodi on the second display, plus the occassional Blackmagic or Ardour sessions. Should not be rocket science here.

That's what I have here whether with KDE Plasma, TDE or IceWM, all using Xorg, no Wayland. The video player can simply be dragged over to the right side display before fullscreening to that display's full size.

Then you are not running separate X screens (multi-head).

Yes, I can do this all day long. I guess you completely misunderstood. The point is, I don't want to be able to drag windows from one screen to the other. I want each screen to be completely confined to its monitor.

This is what I understood until the line I quoted from post #32.

I've had my own issues with this:

https://www.linuxquestions.org/quest...st-4175580302/

My conclusion was I run with whatever NVIDIA dual-monitor stuff is working -- I just reinstalled and set things up and suffer from a slightly worse experience (no real sepearation) in order to gain a better one where things like Steam (kind-of) work.

Yup, I typed that wrong. What I had was 2 X-sessions, one Xorg. Sorry for the confusion. Doh!

I read your aforementioned thread. I too had problems with KDE 3 working at all. I was told back then KDE3 didn't have anyone to work on that part of the code, it was just simply not supported. That was back when I switched from KDE to Mate for that very reason. Presently, the lost functionality seems to be a Mate issue since this does somewhat seem to work in Cinamon, LXDE and XFCE. I will probably just switch to one of these DE's and call it a day.
