Hello everyone. Over the holidays I had a chance to play around with getting my 8x RX580 up and running on Ubuntu 16.04 . There was many issues with booting once I tried to boot with anymore than 6 gpus. This is what got me up and running though.
sudo usermod -a -G video $LOGNAME
Then download and install the driver. This is the Linux Blockchain Driver
wget --referer=[http://support.amd.com](http://support.amd.com/) https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-17.40-492261.tar.xz tar -Jxvf amdgpu-pro-17.40-492261.tar.xz cd amdgpu-pro-17.40-492261 ./amdgpu-pro-install -y
Once you have done that you must run this command otherwise when you boot it won’t work
Then you need to edit the GRUB . Open the GRUB by typing
sudo nano /etc/default/grub
Change the line that says GRUB_CMDLINE_LINUX=""
You also have to change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
Exit and save by pressing control+X (^X), Type Y, hit enter to save the file and then run
Once your PC restarts it should boot into Ubuntu. You can check if the drivers are installed by typing
dpkg -l amdgpu-pro
If you can’t boot into ubuntu and get the black screen that says clean, or you get a bunch of pci bus errors you can get to the terminal by pressing
F2 and run
