Some days ago, I installed Ubuntu 12.04. Since I wanted to use dualview using an external display I installed the propriatary AMD Catalyst 12.4. The graphics are fine, but if I run the updates found by the updates manager, Ubuntu won't be able to start with graphics after reboot. I installed Ubuntu 3 times until I realized what the problem was. So now I got the basic installation with Catalyst running but I can't update the system. Is there any solution to this? Or can I somehow identify which update causes this?

My System is a Lenovo y560 Ideapad (Intel Core i7, 8GB RAM, with AMD Radeon HD 6570M/5700 Series.

Thank you in advance

    Did you manually install the drivers from ATI or did you install them via `apt-get`? – Bruno Pereira Jun 12 '12 at 09:26
  • I downloaded "amd-driver-installer-12-4-x86.x86_64.run" from their website and run this installer. That seemed to work pretty fine. – Innonic Jun 12 '12 at 11:20
  • Ifound out, that if I had installed the updates first, a driver gets installed which is able to manage dual view without catalyst. Is it possible to uninstall the catalyst drivers safely? Then I could simply run the updates and set up my screen. It took me days to set up the computer with all programs so I can't risk loosing anything... – Innonic Jun 13 '12 at 16:04

I took the risk of uninstalling Catalyst using the procedure described here.

After Catalyst had been removed, I could install all the upcoming updates. The open source drivers handle the graphics card with dual view very well.

For any Graphics issue with ati drives- purge the open source fglrx driver and install the proprietary driver off their website.

For some reason i faced the exact same issue with ati driver when the janitor tool within Ubuntu tweak tool deleted my fglrx driver

  • No driver called `fglrx` is open source. There is an open source driver, and there is `fglrx` as provided by Ubuntu's repositories, and there is the `fglrx` driver as provided by the upstream (ATi/AMD) website. But `fglrx` is the name of the *proprietary* ATi/AMD video driver. – Eliah Kagan Jun 25 '12 at 11:05
  • but the one in the repo(archive) is also called fglrx ?isnt it ? – borax12 Jun 25 '12 at 15:24
  • There are multiple drivers for ATi in official repositories. [`fglrx`](http://packages.ubuntu.com/precise/fglrx) is provided in the [Restricted component](https://help.ubuntu.com/community/Repositories/Ubuntu) (the Restricted component provides non-free drivers). – Eliah Kagan Jun 26 '12 at 02:55
