    Intel Linux Graphics Shine With Fedora 12

    Phoronix: Intel Linux Graphics Shine With Fedora 12

    Intel's Linux graphics driver stack is often at the forefront of X.Org / Mesa innovations, from Intel being the first driver having in-kernel video memory management to being the first driver with mainline kernel mode-setting support to even being the driver that often first receives support for new OpenGL extensions in Mesa. The Intel Linux driver stack can be attributed with many firsts, but continually pushing this driver while putting out quarterly timed releases has led to some pains. Earlier this year in fact the driver stack was rather buggy -- especially in Ubuntu 9.04 -- that impaired many users with stability issues, performance problems, and other headaches. Most of the regressions from overhauling the Linux driver stack have been resolved, but where is the driver stack at now? The Intel stack in Ubuntu 9.10 is performing rather well, but where it's more important is its status within Fedora as more of the bleeding-edge graphics packages are pulled into this release that often don't make it into other distributions until months later when they roll out their next releases. To see where the Intel Linux graphics are at in Fedora 12, we ran the same set of benchmarks in the Fedora 10, 11, and 12 releases with an Intel G43 IGP.

    there's probably a bug report for Compiz crashing already. Probably https://bugzilla.redhat.com/show_bug.cgi?id=539789 ?

    Works...almost

    I can log in now, but Compiz crashes. It's not "shiny" but it is enough for me. Thanks!

    m4rgin4l: just checking - you saw I closed your bug as a dupe of https://bugzilla.redhat.com/show_bug.cgi?id=540218 and a kernel build with a candidate fix is now available (well, will be there in a few minutes), right? http://koji.fedoraproject.org/koji/b...buildID=143335

    I tried using abrt (a kernel oops is generated) but it didn't work, I'll try using bugzilla but that thing is a pain in the ass.

    Edit: Filed the bug: https://bugzilla.redhat.com/show_bug.cgi?id=541593

    According to the 2.1 specs (pdf), "OpenGL 2.1 implementations must support at least revision 1.20 of the OpenGL shading language." (page 351, J.1). The latest drivers I could find would only support GLSL 1.10 - and badly at that.

    Personally, I spent the better part of last week rewriting an application to work on a X4500 chip: downgraded to GLSL 1.10, disabled FBO blits, floating point attachments, MRT (which translates to no HDR, bloom, shadows or antialiasing) reduced texture resolution and finally... the driver produced an utterly broken picture. Imagine memory corruption, similar to TV snow, overlayed on top of the actual rendering.

    That was on Vista, by the way. On Ubuntu, the driver simply refused to render any geometry touched by a vertex shader. In the end I simply gave up: Ati and Nvidia cards consume the application just fine, but Intel ones simply do not offer any meaningful OpenGL support. Maybe if you limited yourself to 15-year old GL1.1-level features the drivers might work correctly - but that's simply not an option.

    It's sad to see the largest IHV (50%+ marketshare) produce such garbage. Their competitors are shipping OpenGL 3.2, when Intel is still struggling with 2.1 - and yes this *does* drive developers away from OpenGL and into Direct3D (and Microsoft).

    Edit: Search for Intel on opengl.org to see how depressing the situation really is.

    Please think before you post.

    Intel graphics cards are not directed to "gamers" - they don't give a shit about those people. Integrated graphics are extremely useful for business people and mom/dad types which only want decent 2D and Google Earth. And guess what, they are the most lucrative market since they represent 80% of the graphics card sales.

    Myself, I just bought a new laptop with the Intel X4500 because of 3 things:
    a) I don't play games
    b) Integrated graphics gives 25%+ more battery life
    c) Intel has excellent working open source drivers, and having been burned by Ati and their crappy fglrx I really appreciate that

    Sorry if I'm aggressive, but I'm tired of seeing people complaining about integrated graphics performance in games - come on, do you really expect them to play games? Just don't buy them for that.

    Either way, Intel is also very engaged in the Open Source community with open source drivers, the Moblin platform, etc., so finding other ways to describe this other than "joke", in order to soften your tone, would offer more respect to a significant contributor to the community.
    One word: Poulsbo.

    Not to mention shitty, non-conformant OpenGL drivers across the board. Check out the OpenGL forums if you wish to how developers feel about the nightmare of supporting Intel hardware.

    You may not like it, but Intel is single-handedly holding back the adoption of OpenGL. It's one of the leading reasons why Direct3D is the only real option for consumer graphics.

    So you think *that* is good for the community? Heh, good one - tell us more!

    I don't think that anyone was disputing that Intel accelerators have not served the needs of gamers. I would guess that 80% of the broader market has not cared about games nor 3D to any significant degree. So while Intel chips have not served the needs of games, that does not mean Intel is out of touch of the broader market.

    It's also not hard to argue that 3D is serving a useful need in the general desktop, and there are innovative UI designs that can be accelerated by a GPU, and that the GPU's role in general purpose computing is becoming very significant (offloading video decoding from CPI, compositing desktops, accelerating photo editing, etc.). And Intel can be seen bringing stronger 3D offerings to their product lineup.

    Either way, Intel is also very engaged in the Open Source community with open source drivers, the Moblin platform, etc., so finding other ways to describe this other than "joke", in order to soften your tone, would offer more respect to a significant contributor to the community.
