Tengo una tarjeta integrada intel GMA 3000, o según el lspci
00:02.0 VGA compatible controller: Intel Corporation 82946GZ/GL Integrated Graphics Controller (rev 02)
me genera muchos problemas, no puedo abrir juegos, las barras de titulo desaparecen y aparecen, los botones se mezclan con otras imágenes, no tengo efectos 3D, y mi pantalla de "login" es un caos:
"loguearme" es una hazaña

intente reinstalando los drivers "xf86-video-intel-2.1.4.0" pero no funciono, alguna sugerencia?
