Hi.
I can't get oclHashcat to work.

As long as clinfo doesn't report at least 1 device with type CL_DEVICE_TYPE_GPU (note: GPU and *not* CPU), oclHashcat also won't recognize any OpenCL GPU device.

I would recommend that you uninstall all those fglrx packages and cleanly install the recommended driver from support.amd.com

BTW: there is also a howto for installing the driver under linux https://hashcat.net/wiki/doku.php?id=linux_server_howto , but it is a little bit outdated. But it doesn't matter a lot since you just need to install the newest (recommended - see https://hashcat.net/oclhashcat/ - and supported) driver from the vendor's website (in your case support.amd.com). On the other hand, reading that wiki page doesn't hurt and might help to solve other problems.

I just installed drivers from here and nothing changed. clinfo shows only one entry with CL_DEVICE_TYPE_CPU

EDIT:
I cleanly removed every presence of fglrx, then installed second time - same effect.

Proper xorg.conf generated, is X running, do you have xauth, is DISPLAY exported? All of those things are covered in the wiki article philsmd linked to.

I reinstalled whole system and installed official drivers from support.amd.com.
DISPLAY variable is :0 on both user and root.

Code:
$ xhost +

access control disabled, clients can connect from any host

Code:
# xhost +

access control disabled, clients can connect from any host

I have right xorg.conf generated by drivers.
clinfo shows me still only CPU.

I forgot to mention, that I almost fried my GPU once. It showed me artifacts for few hours, then it got back to normal.
After this, I was still able to use oclHashcat without a problem in exact same setup.

I tried installing older drivers, but I was not able to boot ever again.

I solved the problem by reinstalling whole system with older drivers.
https://support.amd.com/en-us/download/de...s?os=Linux
I use 15.9 version.
I generated rpms from catalyst installer then I installed packages.

Thanks for help.
