Do I and/or How do I install the AMDGPU drivers? Are they included by default?

[Guest]

Hello all,

I haven't installed Kubuntu 16.04 yet. Just trying to figure out what I should expect when to.

I've got two computers. Desktop with R9 380X, which is amdgpu ready and a laptop with R5. I did some research and I found that for laptop, since AMD drops support for catalyst, will have the legacy catalyst drivers (that's cool, not a gamer) which system will have it included. As for desktop, it will use the amdgpu.

My only problem is, I don't know what to expect when I finish my installation for my desktop with the 380x.

Until now, when OS was installed, first thing to do was Driver Manager-> Activate. Set up catalyst manager settings, reboot and all done.

Now what?

How do I do the amdgpu "thing"?

Would be included in Driver Manager? Is there an official link to download drivers and manual install (it has the crimson 15.15 for 14.04 version only)? How do I manually install them?

AMD driver's site doesn't have amdgpu as suggested for 380X.

Excuse me if it is a silly question. I am a bit confused with all these changes AMD does and how will be ported.

Thanks in advance.

AMDGPU is opensource driver so it will work out of box (it is included in kernel). So you don't need catalyst for your desktop neither laptop.

You can test 16.04 live iso. Live iso will be running AMDGPU as well, so if everything works well just go ahead and install it.

Hello all,

you could see what the CLI has to say ,,,,,,

vinny@vinny-Bonobo-Extreme:~$ ubuntu-drivers devices

@ hear it's recomending nvidia-364,,,,,,,,,for you it may say amd

Hello all,

thank you so much for your replies!

So to summarize it, we got two cases:

1) AMDGPU cards - nothing to be done after installation. Drivers are in kernel.

2) Non-AMDGPU cards - As before, either Driver Manager ( its broken atm ) or through terminal using ubuntu-drivers devices and then I guess, sudo apt-get install *choice*

I am a bit confused about the laptop and the R5 card.

schnelle said " So you don't need catalyst for your desktop neither laptop. ". However R5 are not AMDGPU ready and need catalyst. Shouldn't I go for terminal to use ubuntu-drivers?

Thanks again all.

.. the Driver Manager is broken.

Worth noting this work around in the CLI:

ubuntu-drivers list

This will list available drivers and versions so you can then install using apt or apt-get.

I'm not very familiar with AMD/Ati, the one computer in the family that has it has never had problems.

Looking through the packages I believe it won't hurt to install and

Right now the state of AMDGPU driver support in 16.04 is, how would you say, transitional. The AMDGPU driver is the opensource driver - however it's also the only driver going forward. It's built in to the kernel, but there's another version, called AMDGPU-PRO that has the 3D blobs included for OpenGL support and gaming. Both the open source driver and the flgrx proprietary driver are, in effect, dropped starting with 16.04 because the move to X.Org Server 1.18. See http://www.phoronix.com/scan.php?pag...1604-amd&num=1 and http://www.phoronix.com/scan.php?pag...ob-Server-1.18.

Soooooo the issue is...is the computer used for gaming or not? If no, there's nothing to install - as you said, AMDGPU will be automatically initialized in the kernel. For gaming, there's really 2 options: stay on 14.04 LTS with Catalyst driver (fglrx), or stay on 16.04 and wait a month or two for AMDGPU to catch up. It's a small hiccup in order to move forward in a really good way for AMD and Linux. From what I've read on Phoronix, the AMDGPU drivers are MUCH better than the old ones, and even on par and in some cases surpass the nvidia ones.

How do you get the amdgpu driver to work on Kubuntu 16.04?

I have a Thinkpad E550 with hybrid graphics: Intel / AMD Radeon R7 M265.

The Intel card works just fine, but I cannot get the Radeon working. According to AMD, my Radeon is currently supported by amdgpu: http://phoronix.com/scan.php?page=ne...and-Now-Stable .

Here are relevant log files:

I do have a Radeon card:

$ lspci
00:00.0 Host bridge: Intel Corporation Broadwell-U Host Bridge -OPI (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)
05:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Opal XT [Radeon R7 M265]

The kernel module is loaded correctly:

$ lsmod | grep amdgpu
amdgpu                577536  0
ttm                    94208  1 amdgpu
i2c_algo_bit           16384  2 i915,amdgpu
drm_kms_helper        131072  2 i915,amdgpu
drm                   356352  12 ttm,i915,drm_kms_helper,amdgpu

Xrandr does not recognize Radeon as a provider:

$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x49 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel

Xorg is configured to initialize Radeon:

$ cat /usr/share/X11/xorg.conf.d/99-amd.conf 
Section "Device"
    Identifier "AMD"
    Driver "amdgpu"
EndSection

...yet for some reason Xorg does not load it:

$ less /var/log/Xorg.0.log |grep amd
[    12.584] (II) LoadModule: "amdgpu"
[    12.584] (II) Loading /usr/lib/xorg/modules/drivers/amdgpu_drv.so
[    12.584] (II) Module amdgpu: vendor="X.Org Foundation"
[    12.597] (II) UnloadModule: "amdgpu"
[    12.597] (II) Unloading amdgpu

Please help me - I have a very typical setup, and I just don't believe that it is not supported by Kubuntu 16.04...

Try adding amdgpu.exp_hw_support=1 to the grub kernel line.

[grzebo]

No, this doesn't work, I've tried it. The article from Phoronix that I've linked to mentions that this parameter is unnecessary, because this card is supposedly supported as regular hardware, not experimental.

Any other ideas?

[schnelle]

I never had intel processor + amd gpu laptop so I have no experience at this.

But I would try:
1) to look in bios for option to disable intel igpu
2) maybe to blacklist intel driver from loading at boot (i beleive i915 is module name)
3) maybe ask the same question at phoronix forums, there are real gpu gurus there

[grzebo]

Thanks for trying to help.

1) no such option, Intel is the basic card, it has to be on,
2) I want Intel card to be active, that's the whole point of hybrid graphics,
3) I'll try.

[jglen490]

Maybe I'm not getting the point of this thread, but WRT Hybrid Graphics it's a process the links an AMD IGP with an AMD discrete graphics processor. In grzebo's case I don't think it's possible to hybridize an Intel IGP with an AMD discrete graphics card. But, I could be misunderstanding the point.
