I attempted to repeat the issue by installing kernel 4.13.0 using the ukuu utility (I couldn't find how to install the exact kernel that created the issue, so that I could create a bug report). The exact kernel that ended up being installed was 4.13.0-041300-generic. On this kernel, I have no issues.

After a reboot, x broke, with the boot initially started on the my left screen (the run running on an r9 390), and switched to my right screen (Running off the integrated gpu of my Intel 4690-k), where it looked normal. For about two minutes, the screen would very quickly blink about 3 times a second. During this period typing was difficult, with many keypresses randomly missing. However that issue quickly went away. Initially I thought it was a compatibility issue with amdgpu-pro (17.04), however once I uninstalled that, the issue continued unchanged. (where then my system was running the version of amdgpu from the oibaf ppa). Once I managed to return to old kernal, my system returned completely back to normal. I can tell more system details, however won't help with more details of the bug, and I don't want to replicate it and break my system again. I am sorry however that I forgot to take a picture of both screens to show what was going wrong during boot, and the point at where it switched screens.
