    I don't think nouveau is a wasted effort. Its a good research project. Ofc, they will barely catch-up against corporation.
    .. then, if you buy nvidia card, you accept the consequences. You buy a card that should work with nvidia-own drivers on nvidia-supported system, and from windows-like user perspective, its ok. Ie, you buy a piece of hardware with specific performance and specific life-time.

    Its totally not ok, if you believe in free software however. Currently we have Intel doing best in free drivers, but their hardware is very limited.

    I recently purchased laptop with mobile radeon x1900 and HD5850.
    Just gave it a shot, I can sell it off anyway if it doesn't work out.

    You can clock the card. You can get temperatures. You can check card load. You can run games. You can use desktop, its a bit slower than Intel though.
    You have developer attention. Opensource radeon driver is developed, ofc way slower than Intel, but much faster than nouveau.

    Recently you have video acceleration by means of R600+ driver and OpenCL is in the works.

    My experience on opensource drivers is following:
    [x] want automatic power managment
    [x] want mesa to catch-up in terms of still lacking 3D performance

    nothing more. Its way better than I expected, actually.

    Docs can also be crappy and near useless (except for public opinion). If you tried to write a driver for r600 having just the released docs, you'd probably fail miserably. Unless you count existing code as docs. Hey then we have docs, too
    We actually have a nice register database and a shader [dis]assembler. That's just as useful as the stuff at http://www.x.org/docs/AMD/.

    ..Radeon driver holds the leads with power management...
    - Huh, its that bad.

I got a 670gtx with the blob that does what ever I want it to do. I also have a laptop with i5/HD4000 that's working properly "finally"and has good performance for what it is with the latest distos. All did not used to be well until the drivers caught up.
    I'm a blob user myself, but there are some places where the OSS would be needed. For distros with live cd, they usually don't ship the blob on the disk- and it's probably better than just using the fbdev

    That's not a fix, it's a workaround. If you had a fix, we might just care.
    Myself I really don't care (well, I do, but not to the point where I'd do something about it), my ~2000 hours of wasted free time on this project would be even more wasted (on the personal level anyway) if I'd spent them with the annoying bugs of users with cards I don't have (which is the factor that makes fixing things really hard, but don't suggest sending cards to me I don't have the time or nerve), instead of focusing on the fun stuff. It's either progress or stability, and we seem to focus very much on progress over stability overall.

    Or how do you think we manage to keep up (in most areas) with the radeon drivers having no docs and a lot fewer contributors ? Of course, "no docs" is just an excuse, even with docs things wouldn't be moving along much faster at this point because there's no one there to do the time-consuming part, i.e. actually implementing things. That's their biggest advantage, AMD hires devs (and what ever happened to "the community will write the driver" ?)

    Ah, I'm getting more and more frustrated it seems. Maybe I really should just quit as wargames suggests ...

    how about to test source games? CSS TF2 ?

    To address the hostile message by "wargames", this is not wasted effort, since it is about the only way to actually get ANY usability out of nvidia crap without running their virus. I'd much rather run nouveau, even at the significant performance hit, than a hostile blob. In fact, up until about a year ago when I retired my last nvidia hardware, I did just that.
