Created attachment 7119 reload dual monitor settings from xfconf after reconnection This bug continues Bug 11107 - https://bugzilla.xfce.org/show_bug.cgi?id=11107 Patch from #53 of that bug that reenables crts works if second monitor which I turns off and on is rigth-of first monitor. If my second monitor is left-of first monitor, after switching it off an on, all my monitors became mirrored because it enables second monitor on (0,0) coordinates which is correct, but my first monitor has (0,0) coordinates after switching off the second monitor. In xfconf instead my first monitor has (1920,0) coordinates. So, I think that if new output is connected, all outputs must be reloaded. I maked patch and it seems to work. After new monitor connects it reloads data from xfconf and applies it.
It looks like this is the same as https://bugzilla.xfce.org/show_bug.cgi?id=14096 , which has recently had a patch accepted for. I'm experiencing the same issue as you with a 3rd monitor, and the patch in that bug report has fixed it in my trivial testing so far.
