I installed firmware-linux, firmware-linus-non-free, libdrm2 and libdrm-radeon1. I think that radeon is starting with KMS because there is a file called radeon-kms.conf in /etc/modprobe.d/ that contains "options radeon modeset=1".
This fixed the problem for kernels 3.2.0-1 and 3.2.0-2. There is however still a problem with kernel 2.6.32-5 : rectangle of random black and white pixels disappeared but gnome login screen doesn't work. I don't know if Debian want to fix this or not. If yes, I would be glad to help in terms of testing. Thanks a lot for your help. Regards. Johan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
