I upgraded Ubuntu 15.10 to 16.04 today... I wasn't thinking today, definitely failed to read the myriad of warning signs to not install AMD drivers -- but I did LOL facepalm
Note: I downloaded and installed directly from AMD.COM (http://support.amd.com/en-us/download/linux)
now I boot to a 640x480 Login screen. When I login, it just give a error message too quick to read, and immediately I'm back at the login screen.
- I tried all apt-get purge and apt-get remove, but it says nothing's installed
- I followed this page too http://www2.ati.com/relnotes/amd-catalyst-graphics-driver-installer-notes-for-linux-operating-systems.pdf
