direct rendering solo en un display

[Rober Morales <ultimozar@hotmail.com>]

Hola!

tenía configurada una ati9200 con los drivers propietarios y me funcionaba más 
o menos bien, hasta que he descubierto que si inicio sesión en kde con otro 
usuario (y se usa el display :1.0 en vez del :0.0) ya no hay direct rendering 
(glxinfo lo corrobora tras ver caerse/rascar alguna aplicación que usa 
openGL). No es problema de permisos de usuario, sólo depende del orden en que 
entren al sistema. esta es la parte de xorg.conf que habla de la tarjeta, 
generada por fglrxconfig:


GRACIAS
