GBM/KMS issues with nvidia on dispaylink/evdi device

[APokorny]

I have multiple systems with different hyperland versions. On the AMD system hyperland works with the DisplayLink based docking station. On the Intel + Nvidia laptop the rendering with hyperland fails. I built v0.48.1 and v0.8.0

I rebuilt Hyperland and aquamarine to produce these logs

1. Is the issue reproducible in v0.49.0 & v0.8.0?

2. Have you tried specifying only the intel GPU?

3. Have you tried enabling the trace logs? What do they say?

4. You may want to also attach your Hyprland config as a file

   hyprctl systeminfo -c

1. I have not tried 0.49 yet, will have build of that today..

2. Nope not yet - will give it a shot

3. Traces: it seems that setting the resolution fails, the detected resolutions do look though - not using the docking station and directly connecting via HDMI to the individual monitors does work.
