This is on any linux distro, not limited to endeavourOS.
Is there something I have to do to get the files/folders to appear on the right monitor? I mean I could technically drag the files/folders to the right monitor and it would work but any future files/folders I create will go on to the left monitor so that is why I ask this?
Set on Desktop Settings / Icons x Show icons on primary display (if checked all new icons will be on your right/primary desktop)
Panel should be unlocked then moved to primary display and lock again
So all icons created on right/Primary display will remain there. (old ones can be dragged from left to right.)
I put into autostart the above monitor.sh Can be retrieved from here
(Notifications Settings also can be set to appear on primary display)
Most of the problems I understood are solved. Additional hand-out in this theme
