Recent install of Ubuntu 18.04, on a brand new PC setup.
Installed Linux 5.3 using Ubuntu Kernel Update Utility.
Installed Mesa 19.2 through padoka PPA.
Manually pulled firmware files from https://people.freedesktop.org/~agd5f/radeon_ucode/navi10/ into /lib/firmware/amdgpu.
Booting will show the 'Ubunut 18.04' splash screen for around 5 seconds, and then the display will turn black (but still active).
Attaching the dmesg and Xorg.log results to the ticket.
On a side note, I have been able to install the amdgpu-pro drivers successfully, those are functional on the GPU.
