Caturday

Hello. I feel that this article does not meet the notability criteria of Wikipedia (see also WP:BAI). I suggest you merge the substantial content (if any) to 4chan and redirect thence. As it stands, the article will come up on VfD sooner or later. Greetings, Sandstein 01:22, 25 February 2006 (UTC)

reference for nvidia on AIGLX

Hi! You put in an interesting bit about Nvidia not supporting Xgl and AIGLX yet. Could you also provide a reference? I would also reword it a bit different as Nvidia with proprietary drivers is the platform that is working well and recommended for Xgl currently. --TuukkaH 09:07, 20 March 2006 (UTC)

Sure. Added reference. I know it's a forum post, but do keep in mind that the persons title is "NVIDIA Corporation", so I figure this information is from the horses mouth. LainOfIICHAN 12:08, 22 March 2006 (UTC)

I read that forum post in a different way. They say that you can run Compiz on Xgl today, and that they plan to add support for GLX_EXT_texture_from_pixmap in a future driver release (so AIGLX could work too). Perhaps future doesn't mean next so it made sense to change the wording in the article, but how did you add Xgl to that discussion and turned this optimistic statement into "[T]hey will not add support ... until both projects have reached a certain level of completeness."? --TuukkaH 09:00, 23 March 2006 (UTC)

I personally run XGL on my system, and the only way it works is if I use the generic MESA OpenGL libraries, which enables software rendering. AIGLX suffers from the same problems, and even moreso because the AIGLX extensions refuse to turn on at all without hardware-based direct rendering. It was hoped hardware acceleration from nVidia would be in the next driver release, and that forum post says explicitly that the programming extension necessary for hardware-driven OpenGL rendering won't be in the next driver release, but in later driver releases.

Honestly, you're supposed to run Xgl with nVidia's current OpenGL library, as that's enough for Xgl and gives you hardware-accelerated direct rendering. Then you're supposed to run programs such as Compiz that need GLX_EXT_texture_from_pixmap with MESA OpenGL libraries, as that's what provides the extension and Xgl accelerates the requests. I think it doesn't matter which OpenGL libraries you use for the rest of OpenGL programs as the acceleration isn't direct anyway but done by Xgl. Anyway, Xgl doesn't need updates to nVidia's driver, but AIGLX does. --TuukkaH 23:02, 26 March 2006 (UTC)

I realize that MESA works fine. But Compiz/AIGLX both need the extension not provided by nVidia yet. Thus it is not 'supported.' However, you were right about XGL not requiring new drivers to work, but that Compiz does. Changed accordingly. LainOfIICHAN 17:59, 28 March 2006 (UTC)
