Thank you Jan! To be honest I just need several monitors to work, web
browser, KiCAD, FreeCAD, Blender, most of my work I do in a
terminal+tmux anyway :-) Nice image quality, 3D acceleration, and
OpenCL would be really nice to have but not a blocker to work (it
would bring efficiency and comfort for sure). For years I was using
simple vesa video driver on my FreeBSD laptop and I could live with
that. I had another machine for multimedia (macOS). Now  I am working
only on a FreeBSD laptop, so basic work requirements come first. I am
keeping my fingers for DRM KMS Intel for my laptop (multiple monitors)
and AMDGPU OpenCL for my workstation (GPU computing). Threre is no
reason to invest time into something that is dead already (x11-intel).

For years I did work on Xfce4. Now I am working on Enlightenment WM,
they stated Weyland support is already there and they plan to abandon
X11, so maybe its time to play again with Weyland, thanks for
motivating :-)
