Kororaa Releases XGL LiveCD 65

Tony Tony Chopper writes "The team from Kororaa who brought us a GUI based Gentoo installer have just released the first live CD to use xgl technology. From, the lead developer Chris writes 'Today I am happy to release a Kororaa Live CD showcasing Xgl technology.' The response so far have been incredibly positive, an article at is glowing with much praise and few complaints. For those who love eye-candy but don't want to mess with their existing installs, this is the perfect opportunity to see what Xgl is about. The torrent can be downloaded from LinuxTracker."

Kororaa Releases XGL LiveCD

  • Yes, it's pretty. But more importantly I feel like the functionality is there as well. I guess I'm going to force myself to make this work on my current Gentoo box.
    • XGL (developed behind closed doors by Novell replacement for X) is built arround the two main proprietry Linux GL drivers (nVidia and ATI). AIGLX (the Xorg extension started by redhat) is built to work on the open source hardware GL drivers (like Intel 855gm). When the projects exchange code (which is happening) then this will be great. Fancy X effects for those with good and better graphics. I'm looking forward to trying AIGLX when Fedora Core 5 comes out next week.

        XGL [was] developed behind closed doors by Novell

        It doesn't really matters how it was developed; the source code is freely available under GPL. If someone feels they can do better, there is nothing stopping them.

        MountainMan, do yourself a favour and look into the background to this Xgl vs Aiglx thing yourself, because things are not as they have been presented by Fedora. Not by a mile.

        Xgl development is being done highly cooperatively and has been so for many months --- it's all there in the mailing list, for anyone who wants to check the evidence. The business hand of Novell is nowhere to be seen, so all this talk of "proprietary" is the sheerest nonsense, especially since Novell owns SuSE. And on top of that,

      "Well the graphics are cool, but does it actually increase how useable my computer is?"
      Yes. Of course not automatically, but it does provide a technical means that makes things possible that will increase usability. Take the expose like feature, or live previews when alt-tabbing, for example. And will of course make implementing accessibility (sp?) like zooming much easier to implement.

      "Not to mention the obivous questions like "will my crappy integrated graphics card even come close to running this?""
      I think one of the best things about XGL (and AIGLX for that matter) is that the hardware requirements for this are actually pretty low. So if you integrated graphic chip does do opengl, it should work.
      Of course keep in mind that this thing is still in beta and that many drivers still lack the opengl extensions needed, so that many things that later will be done in hardware are now actually done with mesa in software.
      That said, despite these problems, XGL runs very smooth on my quite old and not very powerful Geforce.

    First off, I tried it yesterday and it's really really neat.. I mean giggle like a schoolgirl neat when you first move that jiggly window around. I'm so glad someone finally did this cuz I was about to risk my xorg install to see it :)

    For some reason I can't get the zoom stuff or anything involving the "Windows" key working though. Also, I wasn't able to get any video going in real time-- obviously I can't watch a DVD with the CD already in the drive... and streaming wasn't working. Also, I have two monitors but they weren't both detected.

    But it's so cool. I have no right to complain.

    A question-- Is it just me or is there a kind of aliasing that happens when a window stops moving? It's like it goes "soft" antialiasing as it bounces around, but then just before it snaps back into place it seems to get crisper...

    All in all, this is a great CD to show around. Now when's the AIGLX demo LiveCD coming out? ;)

    I liked how in one of the videos [] apps that freeze or are unresponsive turn black and white to indicate they're "dead". It seems that with depth of field and lighting you could do quite a bit with the UI to hint at an application or window's state.

    For example, as a dialog boxes pops up, at the same time the underlying windows might drop back and fall into a zone that is out of focus, or perhaps individual windows might literally "pop" up (growing larger with larger shadows). The shadows themselves could be "real" I would imagine, and the shadow could be generated via a virtual light source which could be moved manually or automatically throughout the day.

    In short, some of the stuff I've seen seems to have been brought over from OS X, but the power of GLX and AIGLX seem seem to open up a whole new world of GUI possibilities. The zoom effect, combined with vector graphics seems to offer quite a bit to those with visual impairments, for example. Is there a place where UI gurus are talking about new effects that may not only provide eye candy, but increase the usability and even suggest new analogies or interactive effects to make computing easier/better?

      Because a flash drive distro, if not engineered properly, can ruin the device. These things have a limited number of write cycles. For example, if some idiot puts /tmp on the drive rather than in memory, the drive will give up the ghost or would be a lot closer to doing so than it was before after only a few boots.

      Can you imagine what this would do for Linux desktop uptake if it were a living cd instead? After booting up, you have an icon on the desktop that says "Install UbuntuGL". It copies the CD image onto the existing filesystem so the next boot from the CD mounts that as / instead of the cramfs file on the cd. Then bootup is maybe 10 seconds slower than a real install.

      Maybe have the installer also create another file on the disk for the User's home dir. Have it automatically mount the existing filesystems like knoppix does. It would take some hacking, but have an overlay filesystem so they could install any programs they wanted permanently to their 'installed' os. Then people that know nothing about computers can use linux regularly without any hassle.

      Of course not having a working NTFS driver makes this much more difficult technically. But just imagine saying you can replace your crufty Windows interface with Linux's opengl 3d one, for free, and still boot windows just by taking the cd out.

    The effects are cool and all GL stuff flies with speed, but basic xlib stuff in XGL is slow. Very slow. Resizing windows seems like 10 times slower than xorg, for a good test try opening a complex webpage and resize the windows. Is this something being worked on?

    Always when I bring this up it gets dismissed as a configuration error. No, I don't think so. It's the same with this LiveCD as my own compiles before. I have tried on 3Ghz+ computers with Nvidia 6600gt and 6800 cards. In all these demo vides we have seen I have never seen a window resize. If it's just my computers than please upload somewhere a video where resize flies and let me see.

    Before this is fixed all this is just a showcase toy. I understand it's new and not optimized but can we at least agree on that some REAL optimization is necessary? Because before it is as fast as xorg it's just useless for real work, and I would really like to have this.

      I agree with you; I have the same slow resizing, scrolling, text rendering, etc. with a Radeon 9250. It's amazing that the eye-canding is so smooth and fast yet the actual apps are many times slower. All I can fathom is that since every window now has a backing store and gets represented as a texture, this update overhead is to blame, but I really have no idea how it really works.
    • *Rolls eyes*

      Your graphics driver doesn't yet support the GLX_EXT_texture_from_pixmap extension so every time that call is made (near enough any time the window changes) it is going to be emulated in software. As you do that opaque resize just think how many times it might be being called... Don't worry though - your 3D chipset vendor says they will implement it in their next driver release [].
