Ubuntu Mate 18.04 on a laptop with two graphics cards. The Intel works just fine. but the AMD Radeon HD 8690M is nowhere to be seen. All my searching has suggested with starting by checking additional drivers. The problem is that shows as completely empty.

Edit:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
    Subsystem: Dell 4th Gen Core Processor Integrated Graphics Controller
    Kernel driver in use: i915
    Kernel modules: i915
--
01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / R7 M520]
    Subsystem: Dell Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / R7 M520]
    Kernel driver in use: radeon
    Kernel modules: radeon, amdgpu

So it is, in fact, there. Now how do I get the dang thing to recognize it?

The adaper is not missing. It is up and running.

You can run programs using this adapter with DRI_PRIME=1 prefix.

For instance:

DRI_PRIME=1 glxinfo | grep OpenGL

or

DRI_PRIME=1 glxgears

But don't expect much improvement in fps with this adapter.
