I have a Lenovo g40 that came with Windows 10. It came with a AMD Radeon R5 M230with 2GB dedicated memory.

I just installed Linux Mint 18.1 on it and it installed with no errors, but I can't see the graphics card listed and so I don't think it's in use.

The only time I can see the graphics card listed is by issuing inxi -Fxz, but I guess that doesn't mean it's in use. Here's part of the output:

System:    Host: Lenovo-G40 Kernel: 4.4.0-53-generic x86_64 (64 bit gcc: 5.4.0)

So I know the graphics card is there. However I can't see in in lspci or lshw, which is what matters I think.

Here's the output of lspci|grep VGA

00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

And here's the output of lshw -C video

I installed the intel-microcode on the driver manager. The version is 3.20151106.1.

So, I have to say, I am a little bit confused though, since in the Mint 18 release notes it says:

If you are using an ATI GPU in Linux Mint 18, the operating system will either select the Radeon or AMDGPU drivers for you, and these are installed by default.

So shouldn't the drivers have been installed by default?

Anyway, how can I make this work? (I'm trying to avoid downgrading to 17.3 if possible because of UEFI-related issues).

Lenovo laptops have a dual graphic card, a radeon and an intel one. On battery, they switch to the intel on its low power consumption.

The radeon linux driver is a proprietary, binaryonly software and it is far in quality from the amd cpus. Furthermore, this switch and this dualcard support isn't very well developed in them. But it works.

The radeon driver, being a third party source, has to be enabled in your package manager. Search for synaptic in your start menu, and enable it, then run a system update.

  • That makes sense. I installed Mint with third party software enabled though, so I guess it should be there. I do have two questions. What do I check in synaptic to be sure it's enabled? If I type radeon in synaptic, a bunch of things appear (like I said, I'm a newbie when it comes to hardware). And how can I really tell which graphics card is in use? – TomCho Feb 18 '17 at 19:00
  • In case it's important: the only one of those options for radeon in synaptic that's installed in xserver-xorg-video-radeon. And I checked the outputs of the commands I listed in my question with the laptop connected to the power and the outputs are still the same. – TomCho Feb 18 '17 at 20:09

Seems that you have 2 graphics cards in your computer one Intel and Radeon. If you like you can use the intel drivers that works fine. https://01.org/linuxgraphics

I think the installation of this driver is going to configure all X11 stuff.

  • The things is that the Intel graphics are integrated in the motherboard, so not very good. The Radeon card is dedicated, so I'd like it to be the one used. How do I use that one? – TomCho Feb 18 '17 at 18:53
  • I have the same problem. please suggest how can i enable radeon card for my linux mint 18. – Rajnish Kumar Soni Oct 6 '17 at 6:05

Unfortunately, none of the suggestions worked. I read a lot about it and apparently there's just no way. So the answer for this question is: you can't have the Radeon R5 M230 in Mint 18.1 because the support for this version of Ubuntu is dropped (unless maybe you do something really invasive to your system).

The only solution I found to make it work was downgrading to Linux Mint 17.3 and following this awesome answer

EDIT

Since this question has been viewed a lot I think it deserves an edit at this point.

Since I asked the question some development has been made for AMD support in linux. A few weeks ago I installed Mint 18.2 in a computer with a dual Intel/Radeon R5 graphics with the most up-to-date kernel, which at the time was 4.12.

It wasn't my computer so I didn't have the chance to test it properly, but it appears that the system recognized the Radeon card right after the kernel update (I didn't do anything card-related). So I'm guessing as of now the chances of it working are much better.
