I have just upgraded from 14.04 to 16.04 and
lspci -nn reports:
00:02.0 VGA compatible controller : Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16] (rev 0b) ... 09:00.0 Display controller : Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360] [1002:6900] (rev ff)
If I run
glxinfo instead I get:
OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
How can I enable my R7 GPU and use it? Am I supposed to use the AMDGPU driver? Any suggestion to get decent OpenGL acceleration? I don't want to use the integrated i5...
Thanks for your help!
