+1 unable to logon using miner1. Looks like we're stuck in some Ubuntu logon loop. I've tired deleting .Xauthority with no luck 
To all who have problems to login: Are you sure that your card is suported by amdgpu-pro? Check https://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-GPU-PRO-Linux-Beta-Driver%E2%80%93Release-Notes.aspx for this.
@fullzero: Thanks for this nice image. I just installed it (570/580) and it worked like a charm.
Any updates planned?
