It worked previously but I uninstalled the fglrx and tried to reinstall it.
I tried installing it via additional drivers as well as the Ubuntu AMD Catalyst install tool as well as downloading it from the AMD homepage and building a deb as well as just running the script.
I searched the web for a solution for 3 hours now.
