I followed the instruction for an Ubuntu installation, here http://www.phoronix.com/scan.php?pag...item=843&num=1,
but used it to install on my Debian machine. Since I don't use sudo I removed those from the example commands after after copy-pasting them.

However, trying to restart X fails and I cannot even go into kdm, the login manager.

My Debian/unstable was updated/safe-upgrade some minutes before installing the radeonhd.

Any tips on how to proceed?
