    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Thanks for your help, but that didn't work either. It plays as though frames are missing. still choppy, or the same same speed as without the fix.

    I'm interested in that "Tiling" fis you presented. I wonder why my screen freezes? The mouse moves but nothing works.

    Everything works perfectly using the old Harty xorg.conf, EXCEPT no video movies. Screen refreshes fast I can surf the net with speed scroll through docs fine. Its just when I try and play any movies that any player crashes.

    I am almost 100% certain that your MTRR setup is causing slow video playback, so can you please paste the output of the fixmtrr.sh script (preferably output just after restarting Xorg)? I also recommend you disable compiz (Desktop Effects) to ensure it's not interfering.

    It's possible that UXA is incompatible with your chipset, so maybe you should revert to EXA (by removing the "AccelMethod" line from xorg.conf).

    Note that the MTRR fix is necessary regardless of the acceleration method, kernel or driver versions you're using. It affects all Intel graphics users, even with the default Jaunty drivers.

    Did wonders for my graphics, sadly it took away my wireless drivers at the same point, so I'm going to be nosing around to find a work around for them

    Not all Intel graphics users. It's apparently unnecessary on my Dell Vostro 220 with an integrated X4500HD GPU.
    However, UXA still has stability issues, at least without the tiling fix.

    EDIT: With the tiling fix, it's worse.

    Thanks mate! That made the little penguin race down the mountain with ~18 FPS instead of ~4

    Here is some output if good for anything (after applying the fix)

    Judging from your output, you'll need to modify the fixmtrr.sh script:

    Code:
    #!/bin/sh
    echo "Before:"
    echo "-------"
    cat /proc/mtrr
    echo "base=0xD0000000 size=0x10000000 type=write-combining" >| /proc/mtrr
    echo ""
    echo "After:"
    echo "------"
    cat /proc/mtrr
    The part in bold has been customized for your system (graphics memory starting at 0xD0000000 with a size of 256MB, or 0x10000000).

    If you're not sure it worked, modify the script and paste the output again.

    Awsome! Worked on this 82865G (8086:2572) where neither EXA or UXA would previously!!!

    Compiz performance seems restored if not superior to Hardy, and Flash video is INFINITELY faster; anything sub-HD plays perfectly smoothly now without tearing where it was laggy under Intrepid and unwatchable under Jaunty.

    Would be very nice to have a ppa for 2.7.0 intel drivers + libdrm

    I think this is an answer for the same question I have.

    I really like staying within the package manager guidelines. I'm concerned that some ad hoc additions could result in problems if something comes along later via the package manager. I suppose installing .debs is a lot safer than tarballs in this regard. But what about access to kernel upgrades?

    Are my concerns justified or is that just the price for better Intel video performance?

    thanks,
    hank

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Forgive me if I mess up the topic...

    I tried to apply the solution posted above, and I believe it would have worked, but there seems to be a conflict between my xorg and UXA, which might result from a critical crash that occured yesterday on my Kubuntu.

    More info here - https://bugs.launchpad.net/ubuntu/+s...el/+bug/364479

    Any ideas how to force xorg to cooperate with UXA?

    Currently I operate on the recommended packages from the first post, but I had to remove the UXA entry from xorg. Otherwise I wouldn't be able to log in.
