I am facing the same problem since I installed Ubuntu 12.10. I have AMD Radeon™ HD7550M with Intel Hybrid card.
The default driver (not fglrx) that comes with Ubuntu makes the system so slow that it is almost impossible to use in production or even casually for watching a bunch of videos for that matter. Install ATI proprietary card make Unity crash, now I have an OS without Unity and without Windows title bar and borders. Apparently entire compiz does not load. ATI just came out with 12.10 version of their catalyst driver so I tried that too with same result. While doing "aticonfig" i get the "update- alternative warning". I also noticed that my screen is not detected due to some reason... I opened "color" that I use to apply custom icc profile on my screen but I couldn't see it their in the list of hardware. I thought this might be a problem with my discrete card so I tried configuring my system with integrated card with "aticonfig --px-igpu" and now I got Unity and everything loaded. But the performance is very bad and due to some reason transparency is not handled. I see black bars where transparent panels/windows should be. I am at least able to use it though, but if any one got a solution kindly let us know. -- 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
