https://bugzilla.kernel.org/show_bug.cgi?id=217664 --- Comment #12 from Alex Deucher (alexdeucher@xxxxxxxxx) --- The display mux is a switch that controls what GPU the built in display is routed to (dGPU or APU). If it's not set correctly it can route the display to the wrong GPU. AFAIK, it should be handled by the nvidia driver. I'm not sure if they support this or not on Linux. You indicated that the system is still accessible after resume, can you get the dmesg output after resume? -- You may reply to this email to add a comment.
