I=E2=80=99m assuming that it is ha= s something to do with the APU, but I don=E2=80=99t know. Actually, it cou= ld be that Arch Linux uses a vanilla kernel. Perhaps the linux-libre kerne= l doesn=E2=80=99t ship with some certain needed proprietary firmware=E2=80= =A6actually I=E2=80=99m reading online on several places (online) that this= is a problem with mode setting the radeon driver. If I change the grub co= mmand line to disable modesetting, then I may be able to boot properly. T= he problem is that I don=E2=80=99t see grub anywhere in my boot process. There is a brief (5s?) window just after booting the USB where the GRUB menu is shown with a GuixSD background, before Linux-Libre boots. You can press 'e' there to add command-line arguments for the kernel. If adding 'nomodeset' works, maybe we should do that by default. Kernel mode-setting is arguably not that important for the install media. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEu7At3yzq9qgNHeZDoqBt8qM6VPoFAllulZMACgkQoqBt8qM6 VPpJuwf9Fp25sbXToxxaAfFpibjoC5l5goRQuewDx+Hv5gZ007/bhv7AYT/F3YO4 Y/mqWOoVyc5DqboDaBDgXBEH2Ne2kS00EvKPyACQuJz2y4Hxp5JVpars1UnzG4eO GXnyEb8rtPdwZ8GhjuarfHIwI7Ha5rEqYS93QKsPQTDstZsL9gyO6sSyGuYw1jAn juLyQ+Tk0FB7j07Cs1/01GNG0BK9aDz3qxXWh3uAr3YBu2vy7f/KWR0Jqd3z/g1X pC7qT9MdWTNxgcl4nnMyJ5K7vw1A5NP2Yp8XlWH4Qa93dNbXBWRdVkvJ28IGpxqR nawvfS6txoGHtZvdiGzZJ8naGRkWPw== =703R -----END PGP SIGNATURE----- --=-=-=--
