My AMD Radeon RX 580 works very well out of the box (minus a few things like hibernation), except with KMSCON, apparently. If I understand correctly, there are 3 drivers: =2D radeon =2D ati =2D amdgpu The latter seems to work fine on recent cards, but it won't work with older chipsets. I'm not too sure about the difference between radeon and ati.=20=20 Maybe Florian's issue is with an older card that does not support "ati" or "amdgpu". =2D-=20 Pierre Neidhardt https://ambrevar.xyz/ --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEUPM+LlsMPZAEJKvom9z0l6S7zH8FAly68YsACgkQm9z0l6S7 zH8eXgf+L/1CwtwyVHe+sbJADV1j1FJW84Vgf8d4Jbp+mNALe1QWeLQfxZ8Mei+N +RG+BQ4ZuRNZ1rTyFH+giIfnqT/MePQFNT2nzIAunjj0aqvpMjciF3XyKYt3cvis HSpjzMlWHBaf656HJg8ClKItHGIrunnbEIB4TZaKtHyD5bID3Lvirjwyfw05Jrfz zSAq55/SrC9RbHeC6GaHtyrdz84mxvMkZS+i6OzEza57MTfhvE5h5RlTyoBkmPDo Xsruj3fpjVBO3qG4WWdYjrCDxS8WOsCcuF7G/D8VunsrIyxm4pIPEIUlSIPP+5qN dJ4zseE+CaiVqyX+5bNs902H/w2VDw== =pr+a -----END PGP SIGNATURE----- --=-=-=--
