    Phoronix: Testing Out ATI Kernel Mode-Setting On Ubuntu

    Kernel mode-setting for Intel graphics hardware can already be found in the mainline Linux kernel and will be included by default in the release of Ubuntu 9.10 later this year. While Intel's kernel mode-setting support has been maturing in a steadfast manner, this support has not been moving along quite as fast for ATI and NVIDIA hardware. It is possible we will see ATI/AMD kernel mode-setting along with the necessary memory management support enter the Linux 2.6.31 kernel and potentially see this feature appear in Ubuntu 9.10 as an end-user option, but currently this support is still deemed under development. For those with ATI Radeon hardware looking to test out kernel mode-setting, there is now a Launchpad PPA and a LiveCD available for testing out these mode-setting capabilities atop Ubuntu.

    You read my mind. May see Flash become extremely rare for videos within the next year. Yay for open standards and real competition!

    Thankies AdamW, project_phelius, I'll probably try the Fedora 11 livecd and then find out what's needed to do the same on Karmic Koala.

    project_phelius: Do you think that the R600/R700 support would end up being just as crashy as the R430 you tried out? How was 2D support in the driver?

    Not much to see reallly...

    Uggh! These instructions are utterly hideous,
    but that was probably intentional to keep unqualified people (like me from using it. Just download the Fedora 11 RC livecd to play with KMS and DRI2 and burn it to a rewritable dvd and preserve your sanity and xorg config.

    It was cool to play with on my r430 for all of 2 minutes that I ran glxgears and got to see the flicker-free boot and my monitor finally didn't sound like it was being s0d0mized when I did a VT switch (which was instantaneous, nice). It crashed and/or corrupted when I tried to do anything useful with it like watch a movie or play a game or do compiz or composite.

    Not sure how much early adopter info is needed really, the developers seem to have more than enough apps, to flex opengl, xv, plus
    performance regressions and crashes don't take any effort to produce. There really isn't anything to see yet.

    But more test data can only help, so far be it from me to discourage anyone from giving it a go...

    Appreciate all the effort these radeon guys are doing for the linux community!

    Peace out!

    Ubuntu-specific

    The article is very Ubuntu-specific but doesn't really make that clear...

    So, yeah, Fedora is the place to be if you want to be playing with KMS.

    Kernel modesetting is default for ATI chips up to R500 (Radeon X1xxx) on Fedora 10 and 11. You can enable it for R600 and R700 chips with the kernel parameter drm.modeset=1 (though it's still experimental for these chips).

    Kernel modesetting is not default for NVIDIA chips in Fedora 11, but it is available: you can try it with the kernel parameter nouveau.modeset=1 .

    The video doesn't look that impressive because Ubuntu isn't really doing anything with kernel modesetting. On Fedora, kernel modesetting is used to keep the monitor in the same mode all the way from initrd load through to X load, so you get no mode switches (no black screens and sync noises).

    I am pretty much unimpressed right now. But maybe its the video quality.
    First video - nothing happens, you have a black screen, than X. How is that different from the way it is currently done? And oh boy, I hate splash screens so much...

    The second one has me even more puzzled - I mean, switching to a vt is fine. But how is that exactly great news?
    I mean, to demnstrate that KMS works in a way is nice - but what do I get from it in the future?

    I just try to stay with fedora without enabling 3rd repositories (so also no mp3 support) as long as possible ^^.

    And it works, but it would be nice if i got permission by michael to put this on http://tinyvid.tv

    Flash is simply not necessary in my opinion for videos. But yes, no discussion, that's not the topic here, you are right, RealNC.
