package fglrx-updates 2:8.960-0ubuntu1 failed to install/upgrade: le sous-processus script post-removal installé a retourné une erreur de sortie d'état 1

Have fglrx-updates and amdcccle-updates installed
Jockey says driver is not active
$ glxinfo | grep "direct rendering"
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

Haven't tried when fglrx and amdcccle only are installed. I'm tired of it, my system does crash randomly.
