Bug ID: 109130 Summary: 3rd display stays black Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: wolpi.dev@web.de
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 it. 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, too. Maybe driver is relying on BIOS to initialize it?
