hashcat
advanced password recovery

I recently picked up a couple of cheap Radeon 6950 cards and wanted to build a machine that could reliably run hashcat without some of the headaches I kept hitting on other distros.

Yes I realize these are not good cards, plus AMD, but this is really just more of an intellectual pursuit and a fun way to learn about drivers while increase my profanity creativity.
 
I'm a self admitted lurker and have never posted because I was always able to find my answer. I noticed on another thread that epixoip had mentioned that this guide (https://hashcat.net/wiki/doku.php?id=linux_server_howto) was outdated so I thought I would share the minor changes that got things squared away for me.
 
Please note I followed the instructions and ONLY the deviations are noted here.
(It's neat how far you can get when you read the instructions.)
 
Headings are named the same as the original how to...
 
Obtaining Ubuntu Server 14.04 LTS
The link for14.04.2-server-amd64.iso does not work. Instead I obtained 14.04.3 from the official Ubuntu site and verified via their gpg keys and checksums.
 
Post-Installation Configuration
Note: No file named multiarch existed at /etc/dpkg/dpkg.cfg.d
 
Installing a Minimal X11 Environment
roxterm was not found. Instead I installed xterm via apt-get install xterm which worked fine once I got the x session up and running.

Auto-Login
The file lightdm.conf was not created so I created it manually at /etc/lightdm/lightdm.conf and added the suggested entries.
Note: There was no $HOME/.config/openbox/autostart file and manually creating the autostart file did not set xhost at login.

Install AMD Catalyst
I tried a couple of versions of catalyst here and install options but kept having problems.
In the end what worked was a simple apt-get install fglrx followed with the suggested amdconfig --adapter=all --initial -f
 
Below are some of the results.
 
(Please note only one card is show because my new motherboard isn't here yet I'll update if the second card causes any issues.)
 
And finally a big thank you to everyone involved especially atom and epixoip who are very active in this forum and whose articulate posts in other threads have helped me greatly.

Yeah, the AMD article on the wiki is 2 years out of date, as most of us abandoned AMD for Nvidia. There's no real motivation to update it, either.

A rather unfortunate time to buy 6950's as well, since AMD no longer supports this card (and this is why installing the driver from amd.com did not work for you.)
