Hey I'm having a problem with regards to adding an additional GPU to my system.


It is usually a matter of..


aticonfig --initial -f --adapter=all

reboot

Win!


Although after I reboot the xorg.conf gets overwritten and I cannot set clocks, fan etc with aticonfig/od6config.

hashcat recognises the GPU, uh OK.. but I would rather have manual control over the fans and setting the core clocks is impossible.


I've switch GPU's around, tried different slots to no avail and even disabled gpu-manager.

All done on a fresh install of ubuntu 14.04 + latest stable crimson drivers. 15.30

I have a linked the output of a few commands below and I’d appreciate any assistance..

Problem Solved

sudo vi /etc/default/grub

Add "nogpumanager" in the following line
e.g. if you have this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

it should look like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nogpumanager"

Esc :wq to write changes and quit.

sudo update-grub

Reboot

Make sure that the following command returns true:
grep nogpumanager /proc/cmdline && echo true || echo false

If it returns true, regenerate the xorg.conf
sudo aticonfig --adapter=all --initial

=======================
export DISPLAY=:0
sudo aticonfig --adapter=all --odgc
