Like the title says, one screen is black, other screen is normal on login. Both are functional though, minus the fact that I cannot right click on the black screen. In the settings, if I swap the screen positions then swap them back, the problem fixes itself. But if I log out and back in the one screen goes black again. I've tried using both opengl 2.0 and 3.1 compositors, same thing happens on both. My gpu is an rx480 and I'm on mesa 18.0.0 drivers. Anyone have any idea what's going on?
EDIT: I solved the problem. Apparently I mistakenly made a window rule for the plasma shell itself forcing it onto the working screen, so it was not on the black screen where it was supposed to be. So the working screen had 2 instances of plasma shells. I guess KDE can treat plasma shell as a window, which is interesting. Problem is solved, although how do I mark the thread title as such?
