From man 4 intel: There are a couple of backends available for accelerating the DDX. "UXA" (Unified Acceleration Architecture) is the mature backend that was introduced to support the GEM driver model. It is in the process of being superseded by "SNA" (Sandybridge's New Acceleration). Until that process is complete, the ability to choose which backend to use remains for backwards compatibility. SNA is the default acceleration method in xf86-video-intel. If you are experience issues with SNA, try using UXA instead, which can be done by creating an X configuration file containing the following:
/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
El problema es que mi distro, no tiene en esa dirección el archivo :S
[miguel@casita ~]$ cd /etc/X11/xorg.conf.d/
[miguel@casita xorg.conf.d]$ ls 20-keyboard.conf 90-mhwd.conf@
Note que hay un link simbolico en la carpeta referida en el foro, por ello decidí echarme a la mar y navegar entre los directorios del etc
[miguel@casita xorg.conf.d]$ cd /etc/X11/
[miguel@casita X11]$ ls mhwd.d/ xinit/ xorg.conf.d/
[miguel@casita X11]$ cd mhwd.d/
[miguel@casita mhwd.d]$ ls intel.conf
[miguel@casita mhwd.d]$ less intel.conf
Aquí fue donde encontre el dichoso Option "AceelMethod" "sna" y lo cambie por uxa tal y como lo recomiendan y listo!!!!
incluso ya puedo correr el glxgear de open gl
