Excuse my ignorance on the process, but can I add the multiple monitors issue to the New Issues (I don’t seem to have permissions to do this myself)? In very basic terms, since the update, if I try to orientate my second monitor to portrait view with:
xrandr --output DisplayPort-0 --rotate left
there appears to be some sort of Xorg conflict, the system crashes and you are logged out ending up back at the LightDM login screen. I included relevant logs in my original post. This also appears to affect @LS650V as they described with their XFCE scaling issue.
Appreciate your help, and of course the distro itself.
