Description

When I try to use Hyprland "headlessly" (without a monitor plugged in), I get some weird things happening. Specifically, there are 3 symptoms: apps not rendering, log error spam, and weird fps results.

Some of my colleagues investigated and found that it seems like Hyprland tries to allocate a GBM bo with GBM_BO_USE_RENDERING and GBM_BO_USE_SCANOUT flags with the linear modifier. Currently, we can not render to a linear buffer.

Symptoms When I use wayvnc to look at HEADLESS-2, I don't see anything except a gray screen. This error spammed a ton: ``` [ERR] Failed to acquire swapchain buffer for HEADLESS-2 [ERR] renderer: couldn't beginRender()! ``` And, the fps is abnormally low. Here is the output of hyprctl monitors: ``` Monitor HEADLESS-2 (ID 0): 1920x1080@0.06000 at 0x0 description: make: model: serial: active workspace: 1 (1) special workspace: 0 () reserved: 0 0 0 0 scale: 2.00 transform: 0 focused: yes dpmsStatus: 1 vrr: false solitary: 0 activelyTearing: false disabled: false currentFormat: Invalid mirrorOf: none availableModes: 1920x1080@0.06Hz ``` Something like glxgears will run at 1fps, but vkcube will run normally, I think because it doesn't try to sync with the display frame rate. xrandr also shows some weird results: ``` Screen 0: minimum 16 x 16, current 960 x 540, maximum 32767 x 32767 HEADLESS-2 connected 960x540+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 960x540 0.00*+ 640x480 0.00 320x240 0.00 800x500 0.00 768x480 0.00 720x480 0.00 640x400 0.00 320x200 0.00 864x486 0.00 720x400 0.00 640x350 0.00 ```

How to reproduce

This should be done on a machine with no display plugged in and an NVIDIA GPU. I was using Arch, but this may repro on other distros as well. Make sure to have at least 3 "terminal windows" open to this machine (A, B, C). Install Hyprland, NVIDIA drivers, seatd In a different terminal (B), run "sudo seatd -u yourusername" Modify ~/.config/hypr/hyprland.conf and replace "monitor=,preferred,auto,auto" with "monitor=HEADLESS-2,3840x2160@60,auto,auto" In your main terminal (A), run "Hyprland" In a different terminal (C). run "systemd-run --user -S". In terminal C, run " hyprctl output create headless HEADLESS-2" You can observe some of the error spam in the main terminal. In terminal C, run "glxgears", and observe some error spam, as well as a much lower than expected frame rate. You can also use vkcube and see the error spam (fps is normal for some reason). If you want, you can open a fourth terminal and run "wayvnc 0.0.0.0 -L trace -o HEADLESS-2" (-L trace optional) with an app running, to notice that the app doesn't show up on wayvnc (it does show up on sway or with an Arc A770). You can also look at hyprctl monitors to see what hyprland thinks the headless output can output (i.e "1920x1080@0.06" or "3840x2560@60"). This does vary per driver version.

right, nvidia doesn't support that, correct.

@ikalco wanna look into this? It's probably some format calc going wrong
