    Its kind of hard to do TFP in a direct rendered context with a sw renderer, since we rely on the drm to share the buffer objects between server/compositor.

    It needs llvmpipe in indirect context + some fixes in the server to do TFP in there.

      @nanonyme yep I agree you can hardly call out developers for bugs in features that don't exist yet :-)

      @arlied does TFP have applications other than compiz? Textured video? seems that would be faster native anyway though.

        If a computer doesn't have a 3d accelerator you shouldn't be doing 3d...and running compiz or gnomeshell would defeat the purpose of LLVMpipe as well (which is to make software rendering better as they would slow any 3d operations down in user software significantly.)

        LLVMpipe will let people without a 3d card and a fast CPU play a few opengl games... but little more

        I don't I necessarily agree. Whilst yes it is important not to bog down the cpu. It seems that gnome will be relying on graphic acceleration capable hardware more and more.


        The result from this is going to be a very modern (i.e blingy) desktop, I think that regardless though you will want to keep as many people as close to a homogeneous system as possible. Especially if you are selling support and telling people where graphic settings are hidden like canonical is.


        For people who don't even have a smidge of acceleration i think that there are more light weight distros to offer such as lubuntu or at a pinch xbuntu or my personal favorite #!.

          No its pretty much designed to be used for GL compositors, not sure anyone has found any other use for it.

            That's funny.

            SmSpillaz is the most active developer working on compiz, I think he know's what he's talking about.

            Next time try using google.

                Unless the software renderer can get a handle on the X connection (which does make some sense for GLX stuff anyway). VirtualBox does this.
