You need to set Option "AccelMethod" "EXA". You *should* be able to use UXA without DRI and in the testing I've done, it is faster for at least some workloads. You won't get hardware 3d though. I know that I tested UXA without DRI on git master, I don't recall if it works quite right in 2.7.0. On Intel, DRI2 requires UXA and the combination also means that it requires GEM, which we don't have. It really should reject this configuration or fallback more gracefully than crashing X. It attempts to use the fake buffer manager from libdrm and currently I don't see any way that this can work. So, valid configurations for Intel are: Option "AccelMethod" "EXA" Option "DRI" or Option "AccelMethod" "UXA" Option "DRI" "off" robert. --=20 Robert Noland <rnoland@FreeBSD.org> FreeBSD --=-LD+XRsW4MiS/5h0JW3MC Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEABECAAYFAkoETaUACgkQM4TrQ4qfROOfhACeJ2xYcY4CHbbkKUmOZOYs3aiO RL0An3u1hp4D1FuDZcuArLuBdZaulo7p =Spgn -----END PGP SIGNATURE----- --=-LD+XRsW4MiS/5h0JW3MC--
