Describe the Bug

my command is

hyprctl output create headless

sunshine

And, Sunshine release will show "Error: Failed to create GBM buffer" in the log.

Expected Behavior

Sunshine should work with the virtual display

It does work fine for me; my setup differs in the following way:

I have left the capture method and encoder to automatic (capture method might be the issue here)
I have not explicitly specified the adapter name in my sunshine config (i guess it shouldn't make a difference if it is correct)
the nvenc encoder is used instead of vaapi (i don't think that's the issue)
instead of creating the virtual monitor using hyprctl before starting sunshine, I have the following bash script as a prep command: (no clue if that makes a difference in this case)

#!/bin/bash

VIRT_MON_WIDTH=${SUNSHINE_CLIENT_WIDTH:-1920}
VIRT_MON_HEIGHT=${SUNSHINE_CLIENT_HEIGHT:-1080}
VIRT_MON_REFRESH_RATE=${SUNSHINE_CLIENT_FPS:-60}

# create virtual monitor for sunshine
hyprctl output create headless sunshine_mon

# disable regular monitors
hyprctl --batch "keyword monitor DP-1,disable ; keyword monitor DP-2,disable ; keyword monitor DP-3,disable"

# set Sunshine monitor resolution
hyprctl keyword monitor sunshine_mon,${VIRT_MON_WIDTH}x${VIRT_MON_HEIGHT}@${VIRT_MON_REFRESH_RATE},0x0,1

# switch to a workspace named sunshine
hyprctl dispatch workspace name:Sunshine

I'd suspect the capture method might be the issue here, but my log (just like yours does) also contains the following lines (which to me seem to be about the capture method):

So it's weird that it does not work for you when it does for me.
