--- Comment #26 from extr15 <extr15 at 126.com> ---
I can now compile a single radeon module, ref:
http://www.codewhirl.com/2012/04/how-to-compile-a-single-module-in-ubuntu-linux/

however, neither attachment 128481 nor attachment 128780 work for me.
the screen still flicker whether plugged in AC adapter or not.
I am macbookpro 11,5, and ubuntu 16.04.
uname -a:
4.8.0-36-generic #36~16.04.1-Ubuntu SMP Sun Feb 5 09:39:57 UTC 2017 x86_64
x86_64 x86_64 GNU/Linux

tail /var/log/Xorg.0.log:
