It turns out, my problems had two reasons: - I didn't enable KMS and DRM for radeon in the kernel - I didn't have x11-drivers/radeon-ucode installed Both resulted in a fully functioning X server that - could run glxgears just fine - could (with some tuning) render videos in DVD quality with opengl outpu= t - was too slow for videos in any higher resolution Regards, Florian Philipp --------------enig783D3F8856E903F6011E8CC0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlC6FwsACgkQqs4uOUlOuU9UwQCeIyY8IKepigzIPUltdKtQovKy aZwAnjyjxxKI2ztG4wjtB5KKnStSI8rL =nfbQ -----END PGP SIGNATURE----- --------------enig783D3F8856E903F6011E8CC0--
