Need help with the HOWTO: Ubuntu Server guide

[Hopelessone]

Hi,

Ive followed the guide here for ubuntu 14.04: https://hashcat.net/wiki/doku.php?id=linux_server_howto

I used: ubuntu-14.04.5-server-amd64.iso instead of the ubuntu-14.04.4-server-amd64.iso.

I've got no errors throughout the guide, I'm right down at the bottom where it says: Finishing up, when i enter 

Code:

clinfo

i'm getting errors.

Code:

clinfo
modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='fglrx'
modprobe: ERROR: could not insert 'fglrx': Function not implemented
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='fglrx'
modprobe: ERROR: could not insert 'fglrx': Function not implemented
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  156 ()
  Minor opcode of failed request:  19
  Serial number of failed request:  12
  Current serial number in output stream:  12

i tried:

Code:

sudo modprobe fglrx
modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='fglrx'
modprobe: ERROR: could not insert 'fglrx': Function not implemented

Code:

uname -a

I tried purge & reinstall per guide again:

Code:

sudo apt-get purge fglrx*

I have 3x R9 290X's did the guide install the drivers? because the guide says so.. or do i need to install them? what steps do i need to do in order to get them visible in clinfo? Thanks

EDIT: So is 16.04 working for hashcat AMD for R9 290X's? http://phoronix.com/scan.php?page=news_i...id-16.20.3
