Hi,

Note: I do not receive mail from the list, please send replies to me
directly too. Thanks!

I'm trying to set up Wayland on a Libreboot system
(libreboot-20241206rev8_x220_8mb_seabios_txtmode). I'm using SeaBIOS in
text mode, and the first thing I realize is that on my 16:10 display,
FreeBSD only takes about the space for 4:3.

I attempted to install Sway and related Wayland software according to
the handbook, in addition to mesa-dri, mesa-libs, and drm-kmod. I added
kern.vty=3D"vt" in /boot/loader.conf with no effect. Then I tried kldload
i915kms, which caused my screen to flicker for two seconds, then all
text disappears and I am left with a black screen with a few rows of
semi-random white pixels that respond to my input.

Does anyone know how I could begin to debug this? Thanks! I'm on
14.2-RELEASE.

Thanks!
