Hi,
I have an AMD Tonga card with 3 displays attached. Displays at DVI-D-0 and
HDMI-A-0 are working great but the one connected to DVI-D-1 stays black.
X/WindowManager are taking it into account, so windows might be placed on i=
t.
When booting Windows 10 on this hardware the 3rd screen works as well, so
hardware should be alright.
It might be interesting that during BIOS/POST/UEFI the display is black, to=
o.
Maybe driver is relying on BIOS to initialize it?
