I have been running Xubuntu 16.04 without any errors on just the generic drivers that come installed by default. I decided I wanted to play some video games so I installed the AMDGPU-PRO drivers by following the directions here: http://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Install.aspx
cd /tmp tar -Jxvf amdgpu-pro-17.10-414273.tar.xz cd amdgpu-pro-17.10-414273 ./amdgpu-pro-install -y
now when I boot my computer, I see my motherboard startup screen and can access the bios, but if I try and boot the SSD my install is on, I just get a black screen it doesn't appear to be outputting a video signal. I've tried 3 monitors all with the same result, I am not too worried about getting AMDGPU-PRO drivers to work, just with getting my system bootable again. So my quesiton is how can I boot into a state that I can uninstall the drivers?
I've tried SSHing into my desktop from my laptop, but my desktop isn't responding to that.
For anyone looking into this currently, I never solved for 16.04, but a Radeon R9 390 with AMDGPU-PRO is working great on Ubuntu 18.04
