GA107GLM (RTX A1000): nouveau shows garbage on external screen
New Thinkpad P16 has 2 GPU Intel Corporation Alder Lake-HX GT1 [UHD Graphics 770] and NVIDIA Corporation GA107GLM [RTX A1000 Laptop GPU]. Nvidia GA107GLM is the only one used for external screens.
Nvidia GA107GLM is quite new, external screens showed only black and cursor on 6.1.
I experience this on openSUSE Tumbleweed with kernel: 6.2.9, x11: 21.1.8-1.1, xf86-video-nouveau: 1.0.17-4.4, WM: fluxbox.
Nothing obvious in xorg log (mostly i915 related errors), just (EE) Unknown chipset: NV177 (from https://gitlab.freedesktop.org/xorg/driver/xf86-video-nouveau/-/blob/master/src/nv_driver.c#L401):
$ grep '(EE)' /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

I don't see anything obvious in kernel log:
