Benoit,

Great news.
I confirm it works. Thanks a bunch for finding the issue!
Next step I guess is to make gmux work to be able to swicth the nvidia power off whenever we don't need it.
Cheers,
Francois

Dan, do you still need the register dumps (with C pipe)?

- reboot with the patched kernel

I did not try it in BIOS mode, I use it on EFI mode only.

The patch point out the fact that bit-per-pixel of panel is not detected
correctly.

Best regards
