Hashcat 4.1.0 not using AMD RX 570 & amdconfig: command not found

[d5y9nu]

I'm trying install hashcat on a fresh ubuntu 18.04 installation. I'm using an AMD Radeon RX 570. Both my desktop monitors are connected to the GPU (not sure if that matters or makes a difference).

Immediately after installing Ubuntu, I updated:

Code:

$ apt-get update && apt-get dist-upgrade && reboot

Then began following the install instructions as per the hashcat FAQ:

Code:

$ sudo find / -name libOpenCL\* -print0 | xargs -0 rm -rf && reboot

Code:

$ sudo apt-get install ocl-icd-libopencl1 opencl-headers clinfo && reboot

Then I downloaded what I think is the correct driver:

Code:

$ wget https://www2.ati.com/drivers/linux/ubuntu/18.04/amdgpu-pro-18.20-606296.tar.xz

Unpacked it and ran the following:

Code:

$ ./amdgpu-install --version="1.6.180"

No installation errors reported. I ran it again for this forum post, here's the output:

Code:

Reading package lists... Done

amdgpu is already the newest version (18.20-606296).
amdgpu-lib32 is already the newest version (18.20-606296).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

Then rebooted again.

Code:

$ sudo mv ~/.hashcat/kernels /tmp/old_kernels

Then rebooted again. Using `clinfo` only reports 1 platform and its my CPU. After downloading hashcat and unpacking it, I ran it with:

Code:

$ ./hashcat64.bin -b -m2500

But hashcat only uses the CPU. Looking again at the FAQ, I tried the `amdconfig` command but its not found.

Code:

$ amdconfig --adapter=all --initial -f
amdconfig: command not found

Where did I go wrong? I could really use some help.
