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 is provided in the Restricted component (the Restricted component provides non-free drivers). – Eliah Kagan Jun 26 '12 at 02:55
