if select xrender mode,the desktop effect works but very slow
there's nothing changed after enabling deskop effect in opengl mode and apply
Direct rendering is enabled
Extension "Composite" is enabled too in xorg.conf
also ,i have add xcomposite and opengl uses into make.conf and emerge -avuDNt world
still not working

i am upset
my laptop's video card is ati m6 ly with only 8m memory
if i want to enable direct rendering ,i must set default color depth to 16 ,or no rendering at depth 24,beause at least 12m video memory is needed if you want direct rendering to work at depth 24
kwin desktop effect will only take place at depth 24  |

You're lucky that you get any direct rendering with that approximately 10 year old card.  |
