Will update if/when people find more issues and solutions. I take no responsiblity for screwing up your PC.
Assuming you've got WSL installed and all that, I started here, instal VcXsrc, ubuntu-desktop, and mesa-utils. Follow "therealknec"'s instructions and make sure that glxgears is working.
I did most of this yesterday, so I don't remember the exact steps I did next, but I think I tried to run one of the MP-1 samples (Fractals, Fern, etc), which didn't work. Based off the StackOverflow/AskUbuntu pages I have bookmarked and in my history, I probably installed the following packages:
mesa-common-devlibglew-devandlibglewlibglfw3andlibglfw3-devlibglm-devgcc-multilibg++
There might be packages I'm not listing, if you get "can't find header" issue makeing one of the 480 samples, just google it and find the corresponding package. Also, make sure you do source setup.sh and all the stuff in MP-1 2b, and that you set sgpNONE.
Other issues I ran into, and how I (think) I fixed them:
Failed to compile xyzshader
0:1(10): error: GLSL 3.x is not supported. Supported versions are: (supported versions here)
solution: export MESA_GL_VERSION_OVERRIDE=3.0 ES (3.3 had vertex shader issue, 3.0 ES apparently does not. thanks again to Raffael)
/usr/bin/ld: cannot find -lsimpleGLU
solution: cd into SGP/sw, run make
