Greetings,
I apologize if you have already noticed this or are already
working on it, but I wanted to let you know that I have posted
a bug report along with a corresponding patch at:
https://gitlab.freedesktop.org/drm/nouveau/-/work_items/496
The report describes an issue where the nouveau driver fails to
output the correct signal on the DisplayPort of the NVIDIA Quadro 600.
The bug also affects the Quadro 2000, 4000, and FX 1800, but it
does not affect the Quadro K420, K600, and K620.
I would appreciate it if you could take a look. Any assistance
or feedback would be greatly appreciated.
