    Hi,

    I have ubuntu 13.04, kde 4.11.1 and kernel 3.8.
    I removed fglrx to use open source drivers. I had low resolution problem at startup and I solved it removing "nomodeset" option from /etc/default/grub.
    So I decided to install kernel 3.11 and now I have the low resolution problem back, that is when I start ubuntu I get the 1280x1024 resolution, but my maximum resolution is 1920x1080. The /etc/default/grub is the same I changed for kernel 3.8 so I don't understand why it doesn't work well anymore.
    I need kernel 3.11 because it has the optimization for radeno gpu's and at this moment my ATI MSI HD6870 is working at 65 C temperature with kernel 3.8 and I would like see whether I can have some cooler temperatures with kernel 3.11.

    Can you help me for the resolution problem?
    Thanks

      dunno about ubuntu but in arch this problem don't exist, but whatever please try this options in grub(/etc/default/grub) <-- dunno if that exist in ubuntu, if not go directly to grub.cfg

        Probably the best thing to do first, is to check if the radeon driver is actually loaded during boot. Check dmesg, it should show something like this:

        Code:
        [drm] radeon kernel modesetting enabled.

          Are you by chance using the packages from the kernel ppa? Installing those on my machine result in "missing firmware" errors and no hardware acceleration.

            My comments with kernel 3.11:

            * uvd works like a charm even with Adobe Flash!
            * dpm works but IMO it's too easily triggered in upclocking. A simple alt-tab will often upclock to maximum clock for a short period, this wil also ramp up the fan which is a bit annoying.
            * I would like to see hdmi audio enabled by default.

              In which flash/version+browser/version? What site?

                  Currently running kernel DRM-Next 3.11. I am thinking about installing Mesa 9.2 from here and following these instructions myself:

                  I have a some questions, I'm on ubuntu 12.10 and to do this do I need to uninstall my current Mesa version or just install the one from git; and what if I want to uninstall, how would I go about removing the git version and installing ubuntu's official version? Do I simply run make uninstall in the extracted zip folder?

                    You cant just uninstall Mesa, it will take many necessary GUI (x server) components it. On Ubuntu, you either make install and overwrite the old Mesa or maybe use some PPA.
                    If you did the overwrite thing, you will have to reinstall the Ubuntu packages if you want them back - dont make uninstall, you mught break the x server.

                    Note - if you want to use the new dpm/uvd stuff you will need libdrm (2.4.46 or something), xserver-xorg-video-radeon(7.2 if im not mistaken) too at a newer version.

                    PS I install the git version and i overwrite the default mesa on Debian. I never had any problems doing it.

                      Alright, thanks for the info. (btw I have libdrm 2.4.43, DPM works just fine)

                        Do you have "accelerated video rendering, hardware video decoding" if you look at "stats for nerds" right click option?

                          It says: "accelerated video rendering, accelerated video decoding"

                          Also when I start playback of a video on youtube I get a syslog entry:

                          Code:
                          switching from power state:
                           ui class: performance
                           internal class: none
                           ...
                          
                          switching to power state:
                           ui class: none
                           internal class: uvd
                           ...

                            Do UVD clocks take priority over high-performance clocks?

                            For example, it's a pretty known issue that on Windows, if you play a game (high-performance clocks), and open up Flash Player content (Adobe), it will drop both the core and memory clocks to UVD media clocks, leading to lower-performance of the game, and possibly causing system-wide instability on multi-monitor setups.

                              Yes. I see the same behavior on Linux.

                                The UVD clocks are separate from the engine and memory clocks, however, UVD clocks are part of the the power state. There are specific power states for UVD that are designed based on playback requirements and board design. The UVD power state details will vary from board to board. The engine and memory clocks in the UVD power state need to be high enough to maintain apprioriate performance for video playback and support multiple displays, but low enough to handle board specific cooling and power budgets during UVD playback. The UVD state low performance levels are not always as low as the performance levels in the other power states and the UVD state high performance levels may not be as high as the high performance levels in the performance states, but it really depends on the board.
