Stepmania and XGL

I just got XGL working, and I *think* hardware acceleration works.  It there a way to check for certain?

Unfortunately, Stepmania won't run; I get this error.

Error: There was an error while initializing your video card.

   PLEASE DO NOT FILE THIS ERROR AS A BUG!

Video Driver: OpenGL

Initializing OpenGL...
Your system is reporting that direct rendering is not available.  Please obtain an updated driver from your video card manufacturer.

I'm running XGL/Compiz when I run it.  Does anyone know if it's possible to get it working without disabling XGL?

Thanks![/url]

Re: Stepmania and XGL

You should be able to run <code>glxinfo</code> to double check and see if direct rendering is enabled or not...

$ glxinfo | grep rendering

Re: Stepmania and XGL

I don't seem to have anything called glxinfo.

Re: Stepmania and XGL

Ohh...both <code>glxinfo</code> and <code>glxgears</code> have been put in a package called mesa-apps (intuitive ehh?).  This should get you going:

# pacman -Sy mesa-apps

--==EDIT==--
In case you've never run it before, <code>glxgears</code> is a handy program that will draw a set of moving gears on your screen using OpenGL and then report your FPS (frames per second) to the console.  It can be used as a very basic benchmark to see if things are running properly.  Just hit <code><Esc></code> to exit the program...

Re: Stepmania and XGL

OK, that worked, I ran glxinfo, and got

$ glxinfo | grep rendering
direct rendering: No

How can I enable it?

Re: Stepmania and XGL

What video card do you have (ATI/NVIDIA, model)?  What video driver are you running?  How is the device setup in your <code>xorg.conf</code> file?

Re: Stepmania and XGL

glxinfo will report direct rendering to be off in Xgl when normal X says it's on. It's drunk, there is a technical reason but I don't know it off the top of my head. Ask around for someone who uses it, they should know more.
