For those who have hybrid video Intel/AMD. Install "xserver-xorg-video-intel" and "fglrx-updates" from this PPA[1]. After installing it, don't forget to setup "xorg.conf" with "aticonfig" tool. That worked for me.
Obs: now, I'm in trouble trying to enable video GPU acceleration with libva. =P [1] https://launchpad.net/~andrikos/+archive/pp -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1068661 Title: 1002:6740 Unity does not load after installing fglrx-updates Radeon HD 6700M Series To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1068661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
