    Re: Video Accelleration OK, but Firefox performance quite poor!

    To confirm that is not a network issue, GIMP 2.8 is also slow. If I load a descent picture let's say 1200x1200 GIMP gets really slow, and if I try to use the aerographer, on moving the mouse, it gets really slow.

    So again, I think that installing my video drivers was a partial fix.

    Can you tell me how to uninstall them and install ATi open source drivers? just to test GIMP and Firefox performance and give feedback

    Thanks a lot!

    If you

    Code:
    sudo apt-get remove --purge fglrx*
    you will remove the driver. If you log out (I usually restart) and log back in, you will be using the open source driver by default.

    Don't be alarmed if you see that xvba-va-driver is also listed for removal. That is normal. If you reinstall the fglrx driver, you can reinstall xvba-va-driver.

    Well, rolled back to gallium 0.4 and performance issues gone!

    Just to recap, in this thread i had issues with gallium, but to solve them i had to just kill compiz and the issues where gone. http://ubuntuforums.org/showthread.php?t=1980663

    I think that ATi driver caused the Firefox and Gimp slowness, any idea to solve this?

    Best regards!

    PS: Why the open driver is gallium, shouldn't be radeon?

    Well, just readed the radeon driver help page (https://help.ubuntu.com/community/Ra...ing_The_Driver) and got this on terminal dmesg | grep drm

    I think there are issues with both drivers, radeon get slow somehow on certain app running, and ATi gets slow on opening web pages and GIMP.

    I think there is something else afoot here.

    Both the open source and the proprietary drivers work very well for me.

    I'll keep looking.

    If you tell me wich program to use, I can record some screencast of the two drivers performance.

    This is a real shame for Ubuntu, after months of trying, the problem persists. If you want to support hardware acceleration, please suscribe to this bug report https://bugs.launchpad.net/ubuntu/+s...r/+bug/1066313

    PS: Steam on Ubuntu, YES! but warning, you won't be able to surf the web descently!
