Comment 43 for bug 1716857

just one last thing, possibly you are not aware that 19.04 Ubuntu wayland
sessions have exactly the same problem: no external monitors. While this
bug refers to Xorg, the problem is not limited to Xorg. At least on my
Optimus laptop. And when I use its multiplexor to go into pure Nvidia mode,
no monitors work, not even the laptop panel.
