    You can let it install ..28-12 or not, won't affect anything if you're booting into ..30rc4

    I'm getting the same thing (w/ a Dell desktop), I'm just ignoring it (how often do you re-start your computer that it's a problem?)

    I do like new Gnome from 9.04

    BTW, now I'm just realized that my /proc/mtrr already contains a line for the video memory, but with "uncachable" option.

    reg00: base=0x000000000 ( 0MB), size=32768MB, count=1: write-back
    reg01: base=0x0e0000000 ( 3584MB), size= 512MB, count=1: uncachable
    reg02: base=0x0ddc00000 ( 3548MB), size= 4MB, count=1: uncachable
    reg03: base=0x0de000000 ( 3552MB), size= 32MB, count=1: uncachable

    Maybe I need to somehow erase that line before running fixmtrr.sh??

    Also, there are strange messages from logs:
    /var/log/syslog.0:May 7 01:33:07 rg-work kernel: [ 14.320969] mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining
    /var/log/syslog.0:May 7 01:33:07 rg-work kernel: [ 14.320971] [drm] MTRR allocation failed. Graphics performance may suffer.

    Oh yea. I should have realized that. I was just a bit freaked out, I just got the video working perfectly and am afraid of screwing it up again.

    Has anyone that has done this with RC4 found that it doesn't have the power management issues that can cause the overheating? I'd love to do this but that would be a stopper for me.

    G31 works well with uxa enabled using the default Jaunty xorg. The one from ppa, even the stable one crashes it.

    If you're gettting the 404 errors during download you've got to change those files to -2 from -1.
    Code:
    wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc2/linux-headers-2.6.30-020630rc2-generic_2.6.30-020630rc2_i386.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc2/linux-headers-2.6.30-020630rc2_2.6.30-020630rc2_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc2/linux-image-2.6.30-020630rc2-generic_2.6.30-020630rc2_i386.deb http://ftp.us.debian.org/debian/pool/main/libd/libdrm/libdrm2_2.4.9-2_i386.deb http://ftp.us.debian.org/debian/pool/main/libd/libdrm/libdrm-intel1_2.4.9-2_i386.deb http://http.us.debian.org/debian/pool/main/x/xserver-xorg-video-intel/xserver-xorg-video-intel_2.7.0-1_i386.deb

    A towel is about the most massively useful thing for fixing computers. Use it to muffle your screams when you mess up, or to dry your tears if it's broken beyond repair. When all else fails, use it to cover up the useless machine, then walk away.

    Depends on what you mean by "works well". I added this to xorg.conf:
    Code:
    Option        "AccelMethod"            "uxa"
    Glxgears now went from 1600fps to 700fps. A quick TG Motocross (online flash game) test rendered identical unstable and slow performance as before the xorg.conf "Uxa" mod.

    If you read the guide properly, you'd know that glxgears is not a benchmark. The numbers it produces do not benchmark 3D in any meaningful way.

    The difference between "EXA" and "UXA" acceleration methods are major, because if you enable UXA, the new DRI2 rendering framework is used. Although glxgears seems "slower", real 3D applications should be faster (if UXA & DRI2 work correctly on your chipset at this time).

    You do realize that compiz will cause increased CPU usage with Adobe Flash? Although Flash can support hardware rendering, it's explicitly disabled when any composite manager (e.g. compiz) is detected. If your MTRR ranges aren't fixed properly (with or without the newer drivers/configuration), you're always going to experience slowdowns and stuttering in video-intensive applications.
