Hardware 3D Acceleration Guide: x11-base/x11-drm works for 2.6.6 or higher kernels. /usr/poortage/x11-base/x11-drm/x11-drm-20050502.ebuild: "die_error() { eerror "Portage could not build the DRM modules. If you see an ACCESS DENIED error," eerror "this could mean that you were using an unsupported kernel build system. All" eerror "2.4 kernels are supported, but only 2.6 kernels at least as new as 2.6.6" eerror "are supported." die "Unable to build DRM modules." }" The current guide says it doesn't work for 2.6 kernels: section Configure your kernel, "the X11-DRM package currently does not support 2.6 kernels yet" Reproducible: Always Steps to Reproduce: 1. 2. 3. http://forums.gentoo.org/viewtopic-p-2785398.html#2785398
In case of trouble, it's a good idea to try compiling into the kernel or as modules, the kernels DRM or x11-base/x11-drm ebuild, lower AGP from 4x to 2x or 1x in /etc/X11/xorg.conf (doesn't even have to lower FPS of glxgears)...
Thanks. I've updated the guide so that the 2.4/2.6 distinction is less apparent (since they are now both equivalent). I didn't alter the troubleshooting though; I'll need more information (when did it occur and such) and within a new bug if possible.
Thanks for changing it. I think section 2 is perfect now.
