I don't have OpenGL acceleration on my box with an intel 945GM/GME/GMS chipset: The Xorg log says this: momesana # grep -i aiglx /var/log/Xorg.0.log (==) AIGLX enabled (EE) AIGLX error: dlopen of /usr/lib/dri/i915_dri.so failed (/usr/lib /dri/i915_dri.so: cannot open shared object file: No such file or directory) (EE) AIGLX: reverting to software rendering (II) AIGLX: Loaded and initialized /usr/lib/dri/swrast_dri.so momesana # glxinfo | grep direct direct rendering: Yes The used intel driver version is this: * x11-drivers/xf86-video-intel Latest version available: 2.6.3-r1 Latest version installed: 2.6.3-r1 Size of files: 771 kB Homepage: http://xorg.freedesktop.org/ Description: X.Org driver for Intel cards License: xf86-video-intel Reproducible: Always Actual Results: when I try to enable Desktop effects on KDE it falls back to XRender because OpenGL cannot be activated. Expected Results: Pretty opengl accelerated Kde Desktop!
