Hi,

if you do not need OpenGL, try to disable the modules "glx" and "dri" in
/etc/X11/Xorg.conf.

Section "Module"
#    Load  "glx"
    Load  "extmod"
    Load  "dbe"
#    Load  "dri"
    Load  "dri2"
    Load  "record"
    Load  "synaptics"
    Load  "freetype"
    Disable "dri"
    Disable "glx"
EndSection

Regards
Maurizio
