Bom dia para você!
Tenho algum problema com o meu terceiro monitor. Depois que eu entrei, ele mostra apenas 4 pontos e o logotipo Mint no centro
Linux Mint 18 Xfce. Eu tenho três monitores. Dois deles vem da minha Placa AMD dedicada (Radeon HD 6870), O terceiro vai do meu cartão Intel integrado. O system-display-manager vê todos eles e mostra-os como ativos.
Um dia deixei meu pc para dormir, e depois que eu o acordei o terceiro monitor apareceu ... Mas volta após o reinício.
