I get this message when starting SimpleScreenRecorder after upgrade to .04
You are using a non-X11 window system (e.g. Wayland) which is currently not supported by SimpleScreenRecorder. Several features will most likely not work properly. In order to solve this, you should log out, choose a X11/Xorg session at the login screen, and then log back in.
Could someone give the exact command I can paste into the terminal. I am a total noob on this stuff.
As the message said, you have to enable a Window Manager which is compatible with that utility. To do so, you need to go to "Control Center" then "MATE Tweak" (or GNOME Tweak) which will show something like the following:
Default for Ubuntu MATE 20.04 (My Desktop) is Marco. You would need to select from that drop-down for a compatible WM.
"vi" is the default editor for most Unix/Linux OSs. It would be very helpful for you to keep a "Vi cheetsheet" handy. The following are just a few to pick from:

If you haven't done so yet, I would suggest checking out any guidance provided by the original coder's project site:

If you are working with a version that is delivered with the OS distro, you might consider installing directly from the coder. It may have added logic and fixes that could address your issues in general, but not specifically for the fact that you Desktop may not be X-Windows based, for which it was designed.
In a terminal, use this command to create or modify the ~/.xsession file to specify that you want to use Xorg:
echo "exec startx" > ~/.xsession
Log out and log back in; it should use the Xorg session.
