I was noticing that whenever I launched certain composite-extension
binaries it would default to software only rendering. I confirmed that
my xorg.conf has the following:

Section "DRI"
        Group "video"
        Mode 0666
EndSection

, but it did not help. I checked to fix the permissions of
"/dev/dri/card0", but that did not exist per some other recommendations.
I then did a search for "card0" and saw that it existed in
"/dev/ati/card0". I changed permissions there (g+rw) and confirmed my
membership in the video group.  I found that it fixed the software only
rendering issue for Compiz.  Alongside the no-backfill patches, this
helped my machine in many ways like video flickering and speed.
