I upgraded to 14.04 just today and since I'm now using kernel v3.13 and according to This link, I should now be having better support for AMD grapahics.
Is it possible to fix the screen-brightness adjustment issue after this upgrade ? I simply can't change the brightness of my screen. There were numerous solution attempts for this problem on 13.10 but I experienced system-freezes afterwards. Is there a stable solution for this now that I've upgraded to Trusty ?
