Hi. I'm having some problems with XBMC on my Intel G45 board. If I use latest X from git instead of the standard Ubuntu 8.10 packages, XBMS uses "software rasterizer" instead of Mesa OpenGL. I see nothing in the log that helps me. I need X from git to make hdmi audio work. Anyone who knows how I can debug this? This seems to be the relevant parts of the XBMC log:

Thanks for any help,

The software rasterizer stuff is not XBMC fault its X fault. I have same issue on jaunty.

Do you really need latest X for hdmi audio? I have latest alsa and it says I have hdmi audio, not that I have gotten it to work with my TV but my TV sucks and Im not sure it will ever work

Would you mind posting a howto at some point on how to get hdmi audio working with G45? I think lots of users would like that.

Cheers,

Thanks a lot, I can see now that it shows already in glxinfo just like you said. When it comes to hdmi audio you need both a recent x and alsa. Support for it in x was added on nov 6 (or 2.5.1).

btw just searched through intel mailing list. Apperantly you will get OpenGL if you run root, this worked for me

glxinfo | grep renderer will say software rasterizer
sudo glxinfo | grep renderer will say opengl

However adding a DRI with user privilege in xorg doesnt help on me but sudo glxgears gives me 1300fps

Cheers,

hi -

so are you saying if i run xbmc as root it will run with opengl not software rastersizer when using 2.5.1 or the new X (answered my own question - yes you get opengl running xbmc as root). do i need X or 2.5.1 or both for hdmi audio.

i agree - a how to for intel hdmi audio would be fantastic - admitidely not got round to playing with hdmi audio side of things as i'm having major issues just getting analog and optical working on my board. But i will as soon as i figured this out (or just given up)

cheers guys
