      That's a pretty small changelog for over a month of absence since the last driver release.

        Great, I am going to try it out.

        Is there any fix regarding Crossfire?

        I am experimenting a hard freeze as soon as I call any catalyst opengl functionality with a dual 7970 setup.

        http://blog.olivierlanglois.net/inde...e_x_server_wit

        It happens when

        ioctl(13, 0xc03064a6

        where 13 is a fd on /dev/ati/card0

        That pretty much looks like:

        [366895]: Fix hard hang when startx with CrossFire enabled for NI Caicos Pro or SI Cape Verde Pro

        but with 7970s. Waiting this to be fixed to get 7990s.

        I have oprofile data too available. I pretty much know which functions seem to get stuck if it can help you.

        Also can you expand what UEFI support new feature does exactly? I have disabled it on my UEFI system with no noticeable difference.

          Display brightness control on laptops is still not fixed
          OpenGL input in general is a bit more responsive, BUT the corner cases where there was extreme input lag before is still there

          This is a joke.

          On a positive note: OpenGL Shader 4.3 is exposed, less tearing.

            That's what I wanted to know, thanks. Still stuck with Ubuntu 12.10 then.
            Yay, it's all the excitement of having a legacy card "will I get any more updates?" "will I be able to play this game with an old driver?", "when will I be able to use 13.04 or other future ubuntu versions?", but without having a legacy card.

            It's like a legacy simulator -- see all the fun you're missing from being ignored!

              sorry for my stupidity, but does it support 2D Acceleration?
              because it is nightmare if it doesn't. scrolling is slow, moving windows(non opengl Window manager).

                Just to chime in. Brightness control works perfectly for me, infact, it only worked perfectly from release 12.11beta7 onwards. (before that it was a bit iffy)

                Also try to see if you have the ACPI 'video' kernel module loaded. (e.g. try sudo modprobe video)?

                  Well said. That's why we should spread the word

                    I'm using Radeon 6370M 1GB hybrid GPU
                    and the driver still got the same lagg problems on Source based games!
                    2D rendering is kinda slow... for example - firefox is scrolling awfully slow...
                    Atleast some of the 3D rendering drops from 13.4 are fixed...


                    Anyway the situation compared to Nvidia is terrible... i'm really thinking of buying a new laptop with NV card... i can barely stand this...

                      On my 7850 with 3.9.4 kernel performance all round is greatly improved.

                      In cgminer I am getting about 15Mh/s more with identical settings as per 13.4 drivers.
                      In World of Warcraft under wine there as about 10-20fps more on average.
                      Native games already ran fine before so i am not noticing a difference.

                      Tearing I was seeing in VLC/Youtube seems to be gone.

                        i'm still cant use discrete graphic with this driver release.. i'm using Ubuntu 13.04 and linux mint 15, both of them cant use discrete, but when i install in Ubuntu 12.10 it works perfectly
                        my laptop use ATI Radeon HD 7670M Hybrid.. any suggestion why is this can happen? here is error log from Xorg.0.log

                        Code:
                        [   896.539] (II) fglrx(0): Intel display surface mc addr for AMD: 9f083000

                          I found a work-around to resolve the lag in Source games.
                          When I set my KWin compositor to not vsync, then the lag went away. Weird, as when I disable compositing, lag returns.
                          So, maybe the source mouse lag is caused by the compositor?

                          That same "trick" resolved Firefox scrolling smoothness. It isn't as smooth as without compositing, but close enough for me not to care.

                            So I just wondered how the smoothness of everything is affected by cpufrec scaling.

                            When I set cpu governor to 'performance', everything goes buttery smooth...
                            We really need a better default cpu governor.

                            Edit:
                            So I read up on the ondemand docs, and eventually tried the following: (as root)
                            echo 100 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

                            This improved the smoothness of everything, whilst still allowing ondemand to do what it does best :-)
                            A value of 10 for sampling_down_factor didn't resolve the smoothness for me. Also, adjusting the up_threshold didn't make anything smoother for me either.

                            I'm unsure how this affects battery life. I'll report if I notice a change.
