Using two NVIDIA GPUs monitor ok in the first gpu, one is always black on second gpu. ( Although shows the mouse cursor ok)

I’m using cosmic epoch (I’m a gnome user) until this issue is fixed, but you need to delete the Egl-Wayland package (to force you to use only Vulkan backend rendering). I got some rendering on the second GPU messing with the EGL Wayland code. Epoch is still missing some working features like screencast sharing teams, but that’s okay for an alpha release. Although comic-epoch is the only DE that has modern code. (100% Wayland and Vulkan based). Check this Support multi-gpu mosaic · Issue #91 · NVIDIA/egl-wayland · GitHub
