Step 4 of the Hardware 3D Acceleration Guide doesn't mention to emerge x11-apps/mesa-progs so you have the glxinfo and glxgears programs. I took me quiet a bit of google searching to figure that out. Thank You For Your Time And Making Gentoo The Best Distro Step 4: 4. Test 3D acceleration Reboot to the new kernel Reboot your computer to your new kernel and login as a normal user. It's time to see if you have direct rendering and how good it is. Code Listing 4.1: Testing rendering $ startx (No need to load modules for your driver or agpgart, even if you compiled them as a module.) (They will be loaded automatically.) $ glxinfo | grep rendering direct rendering: Yes (If it says "No", you don't have 3D acceleration.) $ glxgears (Test your frames per second (FPS) at the default size. The number should be significantly higher than before configuring DRM. Do this while the CPU is as idle as possible.)
Actually, mesa-progs is installed when you emerge the xorg-x11 ebuild, which I figure 99% of our users do (when they follow the X installation guide as they are instructed to do so in the DRI guide). But for the rest that just emerge xorg-server or a DE, then yes, mesa-progs is needed. I actually added this command to the nvidia guide awhile ago, looks like I forgot to add it to this one as well. Will do.
Fixed in CVS.
