Solved Lost 3d & suspend after upgrade to 13.3

on my Thinkpad x250 with 13.2 everything was functional, but after the upgrade to 13.3 after lid close there is a black screen but no suspend. And no resume, naturally.

Code:
$ glxinfo -B | fgrep Acc
failed to authenticate magic 1
failed to load driver: iris
    Accelerated: no

I'll downgrade again to 13.2 for now, but am moderately curious what the way forward would be.
 
Am clueless what exactly to do. I'll wait for 14.1 and try from there.

Am happy with 13.2 until June.
 
Try the following:


git clone https://github.com/freebsd/drm-kmod.git
cd drm-kmod
git checkout 5.10-lts
make
sudo make install && reboot

tree /usr/src/

how do I populate /usr/src?
 
does just imply you know exactly what and how? I don't.

Which one - /usr/ports/graphics/drm-510-kmod or /usr/ports/graphics/drm-kmod?
I guess the latter - it fits the freebsd version also after going to 14.x.
