    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I finally found a way to run compiz with:
    Code:
    00:02.0 VGA compatible controller [0300]: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device [8086:2562] (rev 03)
    all you have to do is using "Indirect Rendering" option.
    And now my old PC is back to life again (it's even faster than it was with Hardy).

    just to say the bit that says alter the xorg.conf file:
    Code:
    Section "Device"
    	Identifier	"Configured Video Device"
    	Option		"AccelMethod"			"uxa"
    	Option		"EXAOptimizeMigration"		"true"
    	Option		"MigrationHeuristic"		"greedy"
    	Option		"Tiling"			"false" [b]#may break 3D rendering if enabled
    EndSection
    should not have the [b] before the # so should read
    Code:
    	Option		"Tiling"			"false" #may break 3D rendering if enabled
    Though I'd killed my system when it wouldn't run X until i spotted that

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Following the instructions, when I get to the apt-get update step, I get this:

    W: GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4F191A5A8844C542
    W: You may want to run apt-get update to correct these problems

    Any ideas?

    The guide was fetching a different key than I intended, sorry. I've updated the guide with the proper key - follow that step again.

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    OK, so I followed the rest of the instructions. My machine boots to an error message:

    "Ubuntu is running in low-graphics mode

    ...

    (EE) intel(0) Cannot support DRI with framebuffer width > 2048."

    Then I get a few more error messages and my video out no longer works (using a macbook with a DVI piping video to an external monitor).

    EDIT:

    Seems to be related to this bug:

    https://bugs.launchpad.net/ubuntu/+s...el/+bug/146859

    EDIT:

    So I toned down my virtual display to 1900x1280 to workaround the DRI bug and... wow, my machine is really fubared... Now it seems if I boot at all with my external monitor attached, the OS locks up as soon as X starts.

    Maybe my configs weren't quite right when the machine was freezing, because now, with a display size of 1900x1280, I can use my external fine. Of course, the new kernel breaks my sound and my wifi :-/ but a functional video card is more important.

    dentaku65, what's the rationale behind your method? Maybe I'll try it out later today.
