[AMD/ATI] Topaz XT [Radeon R7 M260/M265] [1002:6900] (rev ff) (prog-if ff) !!! Unknown header type 7f Kernel driver in use: amdgpu Kernel modules: amdgpu In order to use the discrete GPU, in Xenial you can prefix any command with `DRI_PRIME=1`. However, with this device, doing this crashes the device. I tried installing a backported kernel that Alberto provided [2] and even though the computer does not crash anymore, it still won't show anything (but the process launched will take 100% of the CPU and cannot be stopped nor killed, it looks...). I tried with the following commands: glxinfo glxgears DRI_PRIME=1 glxinfo DRI_PRIME=1 glxgears Once, I managed to get some output from the `glxinfo` command, with and without `DRI_PRIME=1` prefix: $ glxinfo | grep -i "opengl" OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD KAVERI (DRM 2.43.0, LLVM 3.8.0) OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.2.0 OpenGL core profile shading language version string: 4.10 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 11.2.0 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.0 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions: $ DRI_PRIME=1 glxinfo | grep -i "opengl" OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD ICELAND (DRM 3.1.0, LLVM 3.8.0) OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.2.0 OpenGL core profile shading language version string: 4.10 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 11.2.0 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.0 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions: So it looks like the discrete GPU is used, but so far I couldn't really use it to run anything 3D-demanding. Attached is a Zip with a lot of logs, hope this will help!
