I've scoured the net for the past two days on how to make the OS play nice. I've read some solutions around here and backlinks to other websites and eventually got it booted up with AMD off. Those links were all outdated and it's 2018 now and still no solution. I've installed rEFInd so I'm dual booting with elementary and macOS. Weird thing is that there's 3 boot options!
Check out the gallery to see what I'm talking about: https://imgur.com/a/WNmaG
The first pick (Ubuntu logo) lets me boot the OS but with AMD turned off. The other boots but I'm stuck in a login loop (also I did research on that, no dice). The thing is, when I boot with the elementary logo, it detects my Radeon graphics but can't login to diagnose.
Here's the .xsession-error.log:
openConnection: connect: no such file or directory cannot connect to brltty at :0
Any help is appreciated!
