    Really poor performance after opening some programs (ATi HD4890 Gallium 0.4)

    Hi, i have installed Ubuntu 12.04 on my Intel Core i7 4GBram (DDR3 1333), Gigabyte H55M-USB3, ATi HD4890 and I got really poor performance on ALL effects of unity after opening a small JPG of 1mb with gnome image viewer!

    The fact is that after opening some aplications (in this case the image viewer) the overall desktop performance is really poor (I mean 5 to 7 FPS!!!!!!!!!)

    Is there something I can do to fix that?, I really dont want to switch to jollycloud or Fedora, but, man, this issues come since inmemorial thimes!

    Remember, I have a u$s250 (at launch time) graphics card, so my hardware is not the problem.

    Please, really need some good advise to solve this.

    Thanks!

    PS: ti fix it, I have to kill compiz

    Do you have the fglrx driver installed?

    Are you dead set on the Gallium driver?

    Well, the fglrx driver went really worse!

    So I followed ubuntu official guide to get rid of it and reinstalled gallium, but if there is a better driver, just let me know and guide me to install it, I really want to try. This is the only bad thing think I have to say Ubuntu 12.04

    doubt its the driver. Do the usual upgrade and update and then restart and see what happens.

    Well, that's what i do every single day, update sources, upgrade packages, but no luck, allways is a program that messes crashes compiz and I have to reboot.

    At least, I realized that killing compiz solves the slowness problem withoutrestart, but again, it could be possible that some program messes it all again!

    The fglrx driver works very well, as a matter of fact -- provided you install the one in the Ubuntu repository and do not attempt to compile it from source from the ATI website.

    The difference between the Ubuntu version of the 12.4 driver (development version 8.960) and the 12.4 version released to the public after Ubuntu 12.04 was released (development version 8.961) is little more that a number, but enough to make it problematic for some people.

    The 8.960 version works fine and full hardware acceleration is available for it in VA-API, which takes about 4 packages to install in Ubuntu.

    The Gallium driver is a layer that attempts to generalize the process to make developing easier. General tools are rarely better than specialty tools at a given task.

    How did you install the fglrx driver?

    Oh, I see, I installed fglrx manually using AMDs one.

    Please tell me, how may I install the BEST driver from ubuntu official repos?

    Thanks!

    Remember, the one in the repo IS the ATI driver. The development version 8.960. The difference is that a MOTU has prepackaged it as needed so that it installs correctly.

    Uninstall and blacklist the Gallium driver. Purge the fglrx driver if you haven't done so already.

    Don't install the driver via the additional drivers method, since that has caused some users difficulty.

    Use the terminal:

    Code:
    sudo apt-get install fglrx fglrx-amdcccle
    Some people say to use the fglrx-updates and fglrx-amdcccle-updates versions. This has led to the inability to use the Catalyst Control Center on the six machines I have done that on.

    Then BEFORE you shut down, create an initial xorg.conf, since one does not exist any longer in Ubuntu:

    Code:
    sudo aticonfig --initial
    Reboot.

    After that, to get hardware acceleration via VA-API and the xvba backend:

    Code:
    sudo apt-get install vainfo xvba-va-driver libva-egl1 libva-glx1
    To test that hardware acceleration is working:

    Code:
    vainfo
    You should get something like this:

    Code:
    libva: VA-API version 0.32.0
    Xlib:  extension "XFree86-DRI" missing on display ":0".
    libva: va_getDriverName() returns 0
    libva: Trying to open /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so
    libva: va_openDriver() returns 0
    vainfo: VA-API version: 0.32 (libva 1.0.15)
    vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.7.8
    vainfo: Supported profile and entrypoints
          VAProfileH264High               :    VAEntrypointVLD
          VAProfileVC1Advanced            :    VAEntrypointVLD
    Then use the Catalyst Control Center to make your desired adjustments to your video.

    Some users have reported that Catalyst won't open from the menu. If it won't, just open it from the terminal:

    Code:
    sudo amdcccle
