Since I've upgraded mesa (12.0.1 to 13.0.5) and xorg-server (1.18.4 to 1.19.2), OpenGL programs don't work any longer for non-root users, even when these users are members of the group "video".
The USE flags for xorg-server: doc glamor ipv6 kdrive suid udev xorg xvfb mesa: classic dri3 egl gallium gbm gcrypt gles2 llvm nettle nptl opencl openmax osmesa pax_kernel pic vaapi vdpau wayland xa xvmc I'm using gentoo hardened kernel (4.8.17-hardened-r2). This is the error message: user@puter ~ $ glxgears libGL error: MESA-LOADER: failed to retrieve device information libGL error: image driver extension not found libGL error: failed to load driver: radeon libGL error: MESA-LOADER: failed to retrieve device information unknown chip id 0x683f, can't guess. libGL error: failed to create dri screen libGL error: failed to load driver: radeon As root, everything works fine. I searched the web and also read the gentoo xserver wiki but couldn't find a solution. -- Regards wabe
