bit wrotemmix wrotealthough, xorg doesn't worked well.
mmix wrotexorg(xfce4, tinywm) and chromium works fine with musl libc!
I'm very curious, how were you able to get xorg working?
on my newer amd pc,
using native gcc-musl compiler from alpine linux,(sudo apk add alpine-sdk)
i compiled and installed xf86-video-ati myself.
still it's resolution is not good, it is 1360x768.
on my old amd pc, it uses nvidia onboard gpu,
so i don't have to compile it manually, it work out of box.
chromium is still buggy, it's from alpine repo.
after all, i will return to obarun or devuan. :)

PS: i like alpine linux, it's security. gonna using it for a while.
and i will replace alpine linux on my old pc with s6-obarun.
