Hi Daniel,

Look at your /etc/X11/XF86Config file, Section "Module", and then inside
this section "Module", look for SubSection "extmod". If there's a line :

Option    "omit xfree86-dga"

then comment it with a '#', and X will try to load DGA extension.

Note: DGA is not supported on all cards; if your card is supported,
XFree86-DGA will be listed as a supported extension when you run
the xdpyinfo program.
