I would like to use my Radeon R9 M375 GPU on my Lenovo Z51-70
When I tried
$ lspci -v | grep VGA it gave me this
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09) (prog-if 00 [VGA controller])'
The newest fglrx drivers are installed, but still nothing. Tried to add
GRUB_CMDLINE_LINUX_DEFAULT="radeon.runpm=0" to /etc/default/grub, like a lot of people said, but still not working.
