A few notes, to add to the clutter...

On my HP Envy 17 (Intel 530, NVidia GeForce 950M) xrandr says
...
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis
y axis) 382mm x 215mm
HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis)
1060mm x 626mm
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
...

whn I connect it to my old(ish) Samsung TV; on boot, the TV starts to
mirror the panel after the framebuffer fonts get loaded, X also works
fine (I suppose the second monitor can be made as desktop extension
rather than a mirror, but as I do not intend to actually use it, I
didn't bother to find out how for now, probably another 'Xorg
-configure' with the second monitor and then some tweak).

Mine is recognized, but not served:
...
nouveau0 at pci1 dev 0 function 0: vendor 10de product 139a (rev. 0xa2)
nouveau0: info: NVIDIA GM107 (1171a0a2)
nouveau0: autoconfiguration error: error: bios: unable to locate usable
image
nouveau0: autoconfiguration error: error: bios ctor failed, -22
nouveau0: autoconfiguration error: unable to create nouveau device: 22
...

(at least now, since perhaps 8.99.29, I don't have to disable nouveau*;
earlier it used to lead to panic).

I am in the same place:
...

-rw-r--r-- 1 root wheel 128320 Jan 25 12:48 skl_guc_ver4.bin

Mind you, the message after the skl_dmc_ver1.bin indicates that the file
has been found and opened, but not loaded for some reason. It does not
show if the files are missing. I tried to run with some of the drm debug
options enabled, but didn't get anything interesting. glxinfo then tells me:
...
pci id for fd 4: 8086:191b, driver (null)
i965_dri.so does not support the 0x191b PCI ID.
libGL error: failed to create dri screen
libGL error: failed to load driver: i965
...

which I guess is expected. Otherwise the system behaves well.


Where should I get the microcode from? I copied the two files shown as
missing from
https://github.com/wkennington/linux-firmware/tree/master/i915, wasn't
sure if there is other canonical place to get them from (apparently they
are not in src/sys/dev/microcode).
