Xorg master modesetting regression from xf86-video-intel with multi-screen configuration
With the attached configuration files that should set up two protocol screens, Xorg fails to set up the second screen when using the modesetting driver.
No modes. despite finding a lot of probed modes and the output connected.
A similar configuration using
xf86-video-intel works on the same (Cherryview) machine and uses SNA.
