Title:
DisplayPort MST Hub only recognizes one of two displays using Wayland
(NVIDIA)
Status in Mutter:
Unknown
Status in mutter package in Ubuntu:
Invalid
Bug description:
I have two 4K Monitors connected to a single DisplayPort 1.4 Output
via a DisplayPort 1.4 MST Hub working flawlessly under X.org.
I have enabled nvidia-drm.modeset=1 in the GRUB CMDLINE Settings and
switched to Wayland in the GDM Greeter.
But it seems like Wayland is unable to drive multiple displays via a
DisplayPort 1.4 MST Hub, because only one of them shows a display
output. However they are both correctly recognized under the display
settings.
