Hmmm, I wonder if that's the free stuff without acceleration. I would install firmware-linux-nonfree and check the logs to see that the nonfree version is loading. As mentioned elsewhere in this thread, are you running GNOME? This seems to *need* acceleration features to run properly. So you could attack the problem from the other side of the fence and install a desktop that doesn't require acceleration e.g. xfce, lxde etc. The choice is of course, yours. -- "If you're not careful, the newspapers will have you hating the people who are being oppressed, and loving the people who are doing the oppressing." --- Malcolm X -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
