--- Comment #2 from beniwtv (beniwtv@relamp.tk) --- I have similar problems as 2) and 3) on Polaris hardware (AMD RX 480 8GB reference card) since switching to the 4.15 DC implementation (either self-compiled or Kernel provided by Manjaro).
Every time display settings are changed from the default I'm currently running, or if the monitors go to idle (blank), one or more monitors will report "No signal". For me however, no amount of changing settings will get them back (though they will light up shortly after changing a setting).
Previous Kernels + DC patches did not exhibit this issue.
