I use a debian 5.02 lenny stable linux that I modified to run on my olpc

My window manager is lxde and I had to modify xorg.conf ( not too complicated ) , but the resolution was 900x600 so I had to run lxrandr to modify the screen resoltuion to 640x480 ( very easy )

By the way I used the Binaries you mentionned

I do not use sugar , sorry
