Radeon driver doesn't work with supported Card

Question

I have and Intel HD 4000 and ATI Raedon 8670HD hybrid GPU on my laptop. But, the Raedon GPU is not being used.

Specification:

OS: Ubuntu 17.04

Graphics Card:

01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430] (rev ff)

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

As mentioned in this Question, How to install the open-source "radeon" driver, when I run the following command:

lspci -k | grep -EA2 'VGA|3D'

This is what I get:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
    DeviceName: Intel(R) Graphics 4000
    Subsystem: Hewlett-Packard Company 3rd Gen Core processor Graphics Controller

If I run dmesg | egrep 'drm|radeon', this is the output(Part of it):

So, it seems like Ubuntu knows about the GPU, but it isn't using it.

In /usr/share/X11/xorg.conf.d/ there exists a file named 10-amdgpu.conf and 10-raedon.conf.

The driver is installed and working. Which command confuses you? If you run lspci -k | grep -EA3 'VGA|Display', I think you will be much more happy ;-). If you want to use the adapter, use DRI-PRIME=1. — Pilot6, Jul 22 '17 at 08:45
That's the output: 01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430] (rev ff) DeviceName: Radeon HD 8670M Kernel driver in use: radeon Kernel modules: radeon, amdgpu — code, Jul 22 '17 at 09:19
@Pilot6: I am confused by the chrome://gpu page, which is supposedly using the Intel GPU, and hence gives me poor performance for my GPGPU use case. — code, Jul 22 '17 at 09:20
It is DRI_PRIME=1, not DRI-PRIME=1. Please add output of DRI_PRIME=1 glxinfo | grep OpenGL to your question. Intstall mesa-utils if it is not installed. — Pilot6, Jul 22 '17 at 09:28
And also using radeon in Chrome will not improve performance. Radeon is useful only for 3D. — Pilot6, Jul 22 '17 at 09:29
@Pilot6 That fixed it :D Thank you. If you can post that as an answer, I'll select it. — code, Jul 22 '17 at 09:29
@Pilot6 That's all right. I need to use my GPU for use in WebGl. — code, Jul 22 '17 at 09:30

Your radeon driver is intalled and working.

To use it with some application run it with DRI_PRIME=1, e.g.

DRI_PRIME=1 google-chrome

To check which adapter is used you can run

DRI_PRIME=1 glxinfo | grep OpenGL

to run wuth radeon, and

glxinfo | grep OpenGL

to run with Intel.
