(EE) AIGLX: reverting to software rendering

No, szerintem ez lehet a probléma. Mégpedig, hogy alapesetben lenne támogatás, csakhogy az AIGLX bekavar.

Ki lehet ezt kapcsolni valahol? Nem értek hozzá, mivel nem használok 3d-s asztalt.

Ja igen, xorg.conf-ban a serverlayout-ban tiltsd le és nézd meg úgy a glxgears-t.

Section „ServerLayout”
        Option        „AIGLX” „false”

Illetve bekapcsolt állapotban is.
