==== Support overview ====

Basically, most things work out of the box on this, with %%FreeBSD%% 12 and 13 (from Jan 2021).

Exceptions are the LTE modem and fingerprint reader.

Also, there seems to be no support for the tablet sensor, I get nothing when in devd or anywhere when I fold it into tablet position :(

USB-C only startet to work with 13 for me, but I did a BIOS update at the same time, so I do not know what actually caused it to work.

I have now switched off Thunderbolt in BIOS, and I can’t remember this setting from before, so it might well be the BIOS.

==== Tweaks ====

Needs ''%%acpi_video.ko%%'' for brightness control, ''%%acpi_ibm.ko%%'' does not work for brightness.

For good performance with blender, either start it with

''%%vblank_mode=0 blender%%''

or

''%%LIBGL_DRI3_DISABLE=1 blender%%''

it seems DRI3 is not working, even with the newest i915.ko.
