    I have a dual-GPU system: 6520g + 6750M. Last time I used fglrx, I had problems with brightness and suspend/resume... has that been fixed? Has anyone tried this driver with any HD6xxxM/G (evergreen / northern islands, APU/dGPU)?

    I'm using the FOSS driver, and it is really good, BUT I still have problems: I get a black screen after resume from suspend (related to the APU it seems: https://bugs.freedesktop.org/show_bug.cgi?id=43829 ), and also, I need OpenCL... for which I would have to recompile everything with LLVM, manually, which I'm not technically capable of doing (mostly because I don't know how to fix things when they brake :P ).

    Sadly, I will lose video decoding...

      I could try that. Although they could just tell me "the behavior is according to spec, so please go away".

        When I saw they fixed brightness issues I figured i'd give it a try.
        The brightness slider in l4d2 still don't work (maybe a valve issue?).

        Everything seems the same as the previous beta here.

          Does anyone if there's a patch for kernel 3.13 yet?

            So, the brightness issue is fixed... until you suspend the system. After resume from suspend, you cannot change it. Also, some applications (including AMD's CCC) simply won't run, and I don't know why, because there are no error messages at all.

            Catalyst is great, isn't it?

            I'm wondering why AMD is doing a double effort, even by developing yet another implementation of OpenCL... why cannot we use VDPAU with fglrx, or the AMD APP SDK with the FOSS radeon driver? Why don't they open source catalyst, or at least the opengl parts? Why aren't they giving those sources to their own employees to improve the FOSS driver? Does the PS4 and the XBOne use a third and fourth implementation of the driver?

            AMD should stop developing fglrx and hire more devs for the open source driver.

              That was the issue with the previous Catalyst beta6? The one they supposedly fixed? The issue my notebook currently suffers from?
              I'll have to test with this driver, but will be out and travelling for the next 2 days :-/

                I guess it depends on your hardware and setup... it's funny and sad at the same time. To me, it looks like they always "fix" something for some cards, but brake the same thing or something else for other cards... looks like they are lacking QA.

                AMD: Double efforts, half the results.

                  I upgraded to the newest beta drivers, and it resolved the brightness issue AFTER suspend. CCC runs.
                  Maybe you are running a Franken-driver...

                    Guys update...
                    After some time using this latest beta I figured out a major bug!

                    Kwin with whatever backend and whatever color grid at KDE 4.11.3 when you minimize a number of windows and maximize and minimize again the screen becomes a total mess!! You cannot do anything! A mess with strange triangles!

                    What a shame! And I was about to believe that we are not having serious bugs with this version...

                    openSuSE 13.1, Kernel 3.12, Mesa 10.1git, Radeon HD 5850

                    R600G is really beautiful!! Don't use that thing unless you have to for hardware support and only!

                      I can confirm, that the bug exists and causes problem if you switch to full screen and back artifacts will appear on the screen.
