I'm using an AMD Phenom II X6 1100T (~3GHz, 6 cores). I've got 16 GB
of RAM. My graphics card is an Nvidia Geforce 1060 with 6GB of VRAM.
The screen is a 1920x1080 monitor from Asus.

How would I do that? I tried making a copy of gl.scm (which contains
the definition for the standard mesa package), and stripping out the
non-mesa packages and adding those compile flags, but when I did "guix
package --install-from-file=./gl.scm", it didn't actually seem to do
anything.
Before that I also tried "guix package --install mesa
--enable-gallium-llvm --enable-llvm-shared-libs", but it (predictably,
in hindsight) gave an "unrecognized option" error.

Anyway, thanks for your help, and have a nice day!
