Description
I have a Radeon R9 380 and three monitors EIZO EV2436W. The graphic card has four monitor output ports: DP, HDMI, DVI-D and DVI-I. Each monitor has a DP and a DVI-D input port. Hence, one monitor is connected via DP, one monitor is connected to the DVI-D port and the third monitor is connected to the DVI-I port.
With kernel 4.14.32 all three monitors work. With kernel 4.16.0 and the new graphic core (aka DAL) architecture the monitor that is connected to the DVI-I port is not detected and stays dark.
