--- Comment #44 from Zamundaaa <xaver.h...@gmail.com> --- Okay now the interesting bit would be if fullscreen apps running through Xwayland make the display work - with direct scanout they bypass the normal multi-GPU mechanism. So just use any game from Steam or install Xonotic or something like that from your distros repo, make it fullscreen and drag the fullscreen window to the not-working display with Meta + Left Click. If I'm right then the display should light up. (In reply to Shawn Starr from comment #43) > If this is a kernel bug, why does this only manifest with Wayland and not > X11? Either X is doing hardware accelerated multi-GPU differently in some way that works or it's using the CPU fallback -- You are receiving this mail because: You are watching all bug changes.
