Nouveau - Mar 2022 - External monitor support for GTX 1650 (NV167/TU117)

Hi there,

I just bought an Acer Nitro 5 (AN515-44) notebook with an AMD Renoir iGPU
and a GTX 1650 dGPU. I installed Fedora 35 and, for the most part, it's
working great. The only issue so far is that I cannot use Wayland +
external monitor with Nouveau -- it does recognize the external monitor,
but only renders the top half of the screen, the bottom half remains
(literally) blank.

(BTW the HDMI port is wired to the GTX 1650)

For the record, I can use the external monitor just fine with Nvidia's
proprietary driver on X11, but I'd rather use Nouveau if possible.

I know support for the NV160 family is still coming up according to the feature
matrix <https://nouveau.freedesktop.org/FeatureMatrix.html>, so I'll
patiently wait. I just wanted to volunteer to do some testing on this
specific setup if this can help in any way. Just let me know.

Keep up the great work!

Cheers,
Andre

Hi Andre,

You're going to be best off filing a bug at
gitlab.freedesktop.org/drm/nouveau with some details of your setup:

1. lspci -nn -d 10de:
2. Your vbios (/sys/kernel/debug/dri/1/vbios.rom)
3. Your monitor's EDID, esp as reported when plugged into nouveau
(/sys/class/drm/card1-HDMI-1/edid or the appropriate connector)
4. dmesg after nouveau is loaded and monitor plugged in

This should allow all the info to be well-contained and accessible to
everyone who needs to see it.

There aren't any currently outstanding known issues that I can think
of that would cause your current situation. But plenty of unknown
ones!

Cheers,

  -ilia
