SOLVED. My problem was dued to ATi drivers previously installed from ATi packager 's .debs and not to envy ones! I had installed Cat 8.4 from ATi build .deb to test them out. Unfortunatly diversion on file LibGL.so.1 wasn't removed by ATi deb uninstall. The result was a "corrupted system".
Thanks to Alberto I've figured out how to solve it: sudo mv /usr/lib/fglrx /usr/lib/bakfglrx sudo dpkg-divert --rename --remove /usr/lib/libGL.so.1 sudo rm /usr/lib/bakfglrx Now everything is back to normal. With envy packed drivers running great.
