I'm having the same problem when installing 12.10 from the AMD website. It works fine with the fglrx and fglrx-updates package from Ubuntu repository, and with 12.9 BETA from AMD website.
The update-alternatives warning highlighted in this bug report is probably a red herring - the actual problem is most likely as mentioned in the other report. https://bugs.launchpad.net/ubuntu/+source/fglrx-installer- updates/+bug/1069199/comments/3 -- 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-installer Radeon HD 6700M Series To manage notifications about this bug go to: https://bugs.launchpad.net/fglrx/+bug/1068661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
