Eu tenho esse problema com todas as versões do AMDGPU-PRO e desde o início da minha compilação. O Ubuntu irá travar meu monitor, teclado e mouse quando eu ligar meu monitor ou alternar entre as fontes de exibição. Tenho dois monitores Panasonic Viera TX-65DXW784 conectados usando dois adaptadores Club 3D DisplayPort 1.2 a HDMI 2.0 UHD Active em um VTX3D Radeon R9 Nano.
O erro parece estar relacionado ao drm (veja syslog). O O / S ainda está em execução e posso ssh nele. Mas não consigo reiniciar o Unity.
