    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I'm wondering why my 9.10 installation doesn't have xorg.conf at all by default.

    Karmic doesn't use an xorg.conf configuration file.

    So when I upgrade to Karmic tomorrow, I don't have to worry about reverting the xorg settings?

    None of the configuration options from this guide will affect the 2.9.0 driver. UXA is the default - and only - acceleration method, which also makes the EXA options useless.

    You can delete your xorg.conf after upgrading to Karmic (but keep a backup, as Karmic no longer presents an easy way to generate blank xorg.conf files).

    The fixmtrr.sh script is still useful if you restart Xorg (which is surprising; I thought the bug was fixed properly).

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Any tips on what to do if you have upgraded to Karmic?

    A couple of weeks ago i updated my xserver-xorg-video-intel drivers (still using jaunty 9.04) as it were a part of the system update program. Since then my graphics performace have been seriously degraded. I can not use anything other than 'None' under Visual Effects where I could previously use 'Extra' with not a hint of a glitch. Even when turning visual effects off, my system is extremely slow graphic-wise, i can't even move the mouse pointer smoothly.

    I am using a laptop with Intel i45GM chipset and Intel GMA 4500MDH graphics card. I've been living with this problem for some weeks because i thought it would be sorted out in Karmic but obviously it has not.

    Can confirm this.

    After more than a week testing new driver, I must say that improvement is barely noticeable.

    Youtube standard videos are still working sadly, not to mention that HD trailers are seen like a slideshow.

    To be honest, I gave up on Intel GPU Linux driver support, that I'll never buy a product with it again

    Generally I'm optimistic, but regarding intel driver future, bah...

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    After upgrading to Karmic, I completely lost all of my graphic visual effects. Karmic couldn't locate any drivers to turn them on. I finally fixed this by editing my xorg.conf (which Karmic reset) and applied the fitmtrr.sh script again, poof! everything back to normal.

    Can someone explain this to me, since Karmic doesn't use xorg, or uses it differently?

    Oddly enough, I was having troubles before: brightness only adjusted randomly, screen flickered to different brightnesses whenever it wanted too, etc.. those have all gone away! Why is this?

    Thanks
