you were right:

[    2.415947] [drm] nouveau 0000:01:00.0: Unsupported chipset 0xffffffff

this is why the screen freezes when I try a switch to the nvidia card?

also, when you have some time, could you explain us how to play witch
acpi_call to figure out how to switch the mux?

thanks you very much
