I have a new laptop with Alder Lake graphics. While Linux now as the device is listed as stable on the latest kernel, FreeBSD is not there, yet, and probably won't be until it reaches a long-term support version. That leaves me with a nice paper weight.

I assume that I should be able to use SCFB or VESA toi et some graphics support, but the attempt to start X results in a log entry that no graphic device can be found. pciconf -lc reports:

gapci0@pci0:0:2:0: class=0x030000 rev=0x0c hdr=0x00 vendor=0x8086 device=0x4628 subvendor=0x17aa subdevice=0x22e8
vendor = 'Intel Corporation'
device = 'Alder Lake-UP3 GT2 [UHD Graphics]'
class = display
subclass = VGA

How do I make X recognise this device so that I can get graphics to work?

Something like this, maybe?

pkg install xf86-video-scfb

cat >/usr/local/etc/X11/xorg.conf.d/driver-scfb.conf<<EOF

Section "Device"

Identifier "Device0"

Driver "scfb"

Option "NoAccel" "On"

EndSection

EOF

Best

Thanks!
