Fixes for AMD installer (Ubuntu 16.04 x86_64 dec 30,2017)

I just did a fresh install of Ubuntu 16.04 to a new partition, and did an 'apt upgrade ; apt dist-upgrade' to make sure it was perfectly up to date.

After installation finishes, are these steps correct to get AMD-APP-SDK working?

1. install amdgpu

2. install AMD-APP-SDK-v3*

At this stage, several things are missing:

* LD_LIBRARY_PATH is missing /opt/AMDAPPSDK-3.0/lib/x86_64/

* The dir (/opt/AMDAPPSDK-3.0/lib/x86_64/) contains an incorrect symbolic link ( incorrectly points to /usr/lib/ [which doesn't exist]) which can be fixed like:

  $ rm

  $ ln -sf sdk/

  $ ln -sf sdk/

However, 'clinfo' fails with:


terminate called after throwing an instance of 'cl::Error'

  what():  clGetPlatformIDs

Aborted (core dumped)

What did I miss or do wrong? I'm trying to get 'clinfo' working.

Ok, my 'fixes' aren't required at all. I documented the steps required to get things working here:

It's all working perfectly thanks to help from Dipak.

I'd just like to add that strace revealed that clinfo was trying to find, but that needs another LD_LIBRARY_PATH change:

export LD_LIBRARY_PATH=/opt/AMDAPPSDK-3.0/lib/x86_64/:/opt/AMDAPPSDK-3.0/lib/x86_64/sdk

clinfo works now.

Also, xmr-stak gets a little further: Found AMD platform index id = 0, name = Advanced Micro Devices, Inc.


However, the next log line that xmr-stak prints is:

WARNING: CL_DEVICE_NOT_FOUND when calling clGetDeviceIDs for of devices.



Strange, I don't think that clinfo (or the AMD libraries) are actually finding my AMD RX 580.

lspci -v shows:

Are the AMD drivers finding the RX 580 at all?

Adept II

I'd just like to add a few things:

I've read that the 'pro' driver includes OpenCL. I thought that perhaps that's why my RX 580 isn't being found via 'clinfo'.

I downloaded and installed the AMDGPU-Pro Beta Mining Driver (17.40-483984) (using amdgpu-pro-install -y).

The mining driver seems to be initialized fine (dmesg, lsmod -v). However, clinfo still doesn't show the RX 580 in its list of OpenCL devices and no mining software finds the RX 580.

I'm not sure what to try next.

My system is using an Intel GPU for X11. My plan was to have the RX 580 just sit there and mine (not connected to any monitor).

Are there any BIOS settings at play?

Any and all suggestions warmly welcomed.

It seems that neither of the AMD-PRO drivers work with X11 - they both segfault like this:

[7.177] (EE) Backtrace:

Fatal server error:


7.177] (EE) Caught signal 11 (Segmentation fault). Server aborting

I also see an ABI mismatch in the X11 logs (causing a segfault):

[ 6.761] (II) Module amdgpu: vendor="X.Org Foundation"
[ 6.761]compiled for 1.19.3, module version = 1.4.0
[ 6.761]Module class: X.Org Video Driver

[ 6.761] (II) Unloading amdgpu

6.761] (EE) Failed to load module "amdgpu" (module requirement mismatch, 0)

I've uninstalled amdgpu-pro and the AMD-APP-SDK, then re-installed them - just in case my previous install of the normal (NOT PRO) amdgpu drivers had some lingering effect.

No change:

* clinfo still aborts unless you manually provide your own LD_LIBRARY_PATH

* clinfo still fails to find the RX 580


* X11 no longer works. I get:

root  1209  0.0  2.1 378828 43480 ?   

Sl   12:12   0:00 zenity --warning --text <big><b>The system is running in low-graphics mode</b></big>\n\nYour screen, graphics card, and input device settings\ncould not be detected correctly.  You will need t

It doesn't matter if I select the PCI Express video card as the primary video card in the BIOS. The Intel graphics chip is no longer used.

In the failsafe X11 logs I see another ABI major version mismatch:

[14.662] (II) LoadModule: "glx"
[14.662] (II) Loading /opt/amdgpu-pro/lib/xorg/modules/extensions/
[14.663] (II) Module glx: vendor="X.Org Foundation"

[14.663] (II) Unloading glx

14.664] (EE) Failed to load module "glx" (module requirement mismatch, 0)

fbdev seems to fail with (this EE error is printed dozens of times):

[14.752] (EE) FBDEV(0): FBIOPUTCMAP: Invalid argument

So maybe that's why X11 no longer works at all (not with amd or intel graphics).

Again, I'm using the latest dist-upgrade of Ubuntu 16.04.

I'm happy to try anything. I'll reformat, re-install, even purchase another motherboard.

I'm curious if the AMD driver needs to be running under X11 for OpenCL to work?

I found an OpenCL howto:

OpenCLHowTo - Andreas Klöckner's wiki

and it says "the X server has to be running, and the OpenCL code has to have access to it.".

Can anyone here confirm this? It seems weird to me (as an OpenCL newb) that an X server is in the picture at all...

Fwiw I compiled the OpenCL howto demo and it also couldn't find the RX 580 as an OpenCL device.

(again, maybe the X11 ABI major version mismatch is the root culprit?)

Adept II

Just a FYI - the AMD Vulkan demos build and run fine. A snippet from the vulkaninfo example I compiled shows it finds the RX 580 just fine:

VK_LAYER_LUNARG_core_validation (LunarG Validation Layer) Vulkan version 1.0.65, layer version 1

    Layer Extensions    count = 1

        VK_EXT_debug_report                 : extension revision  6

    Devices     count = 1

        GPU id       : 0 (Radeon RX 580 Series)

        Layer-Device Extensions count = 1

            VK_EXT_debug_marker                 : extension revision  4

I suspect my main OpenCL problem stems from an Ubuntu update for X11 and the AMD drivers haven't caught up yet (ABI major version bump).

Too bad no monero miners work with Vulkan 🙂

Adept II

Another FYI - I was able to use a Mesa OpenCL ICD package to move forward (or move sideways, I can't tell)

sudo apt install mesa-opencl-icd

clinfo now finds the RX 580.

Also, some small C code (tools-master print-devices) shows:

platform 1: vendor 'Mesa'

  device 0: 'AMD POLARIS10 (DRM 3.20.0 / 4.4.0-104-generic, LLVM 4.0.0)'

So... the problem is that only OpenCL 1.1 is supported and I seem to need OpenCL 1.2 for xmr-stak.

Also, xmr-stak is complaining that the platform is not 'AMD' (it's Mesa). Not sure if that's why it's still crashing (I suspect missing OpenCL 1.2 support)


Please do not install APPSDK with amdgpu-pro as APPSDK is no longer compatible with this driver. All the required libraries come with the driver itself.
