    Unhappy Galago's graphics performance issue after installing Intel video driver

    Hello everyone,

    In order to solve the problems reported in posts like this: http://ubuntuforums.org/showthread.php?t=2168352 I installed Intel's video driver in my Galago. After installing it, the problem is solved indeed, but I experience that graphics performance is slower than before. I tested it in, for example, Team Fortress 2 and it works slower, and it also happens with Unity's User Interface. Has this happened to anyone else? How did you sort it out?

    Thank you in advance

    Re: Galago's graphics performance issue after installing Intel video driver

    I too have installed the 01 drivers, and also agree the graphics performance is not what I would expect. The fade-in and fade-out of the Unity dash has a very noticeable lag most of the time.

    The repository only has Mesa 9.1 in it, and supposedly mesa 9.2 has a bunch of haswell performance improvements. So I just chalk it up to these drivers still being a work in progress and was going to tough it out until next release. If you're determined you want a fix now, perhaps you can figure out how to get 9.2 on Ubuntu, or maybe install 13.10 or something else a little more bleeding edge that would have it. I haven't done these things yet though so I make no promises! Has anyone else?

    Our preliminary testing with Ubuntu Saucy is indicating a performance gain of around 2x compared to 13.04. We strongly recommend all Haswell users upgrade to 13.10 once it's been released.

    Re: Galago's graphics performance issue after installing Intel video driver

    Did you try a mix of intels latest drivers, mesa 9.2 and kernel 3.10.10(latest stable), perhaps try latest 3.11RC7 kernel also?

    http://linuxg.net/how-to-install-the...and-derivates/

    for mesa:

    sudo add-apt-repository
    ppa:xorg-edgers/ppa
    sudo apt-get update && sudo apt-get upgrade

    To see what Mesa version you have:

    glxinfo | grep "OpenGL version"

    Re: Galago's graphics performance issue after installing Intel video driver

    I am also experiencing graphics performance issues after installing the Intel driver (from this thread).

    I removed the PPA and downgraded the packages to remove the new driver using ppa-purge:

    Code:
    sudo apt-get install ppa-purge
    sudo ppa-purge -s download.01.org ppa:gfx/ubuntu
    This seems to have fixed my performance issues.

    I downgraded as per the instructions and my computer is still acting very funky and slow. Also, strangely enough the webcam is still working with those other apps.

    Re: Galago's graphics performance issue after installing Intel video driver

    just an update here: I forgot to mention that I was on the low-latency kernel. even after purge that was really, really slow/affected. I rebooted into the standard kernel and all seems fine (at least for the past hour - I will update if that changes). And in both cases, the webcam is still working with jitsi. So... the purge did not help the low latency kernel. Also, I realized that I had not tested the upgrade with the regular kernel. So I am tempted to reinstall the new intel driver and see if things are still ok with the regular kernel...
