I have what I believe is an identical issue on gentoo using hyprland. In obs startup I see a glimpse of the hyprland default wallpaper which quickly disappears, then it’s just a black screen. I can select the monitor I wish to share, by adding the screen source (pipewire) which takes a moment to load up and then I select my monitor, but it stays black in preview and on any streams. I get the following in the terminal when I add my screen as described in the paragraph above ^: I’ve confirmed my user settings, permissions, env, dependencies, etc. it seems xdgh is presenting momentarily (hence the splash screen of the default hyprland wallpaper), but pipewire doesn’t seem to know what to do. Possibly unrelated — I get the default wallpaper splash on reboots too — so this makes me wonder if pipewire simply fails due to my wallpaper overriding default… 🤔 |
|
I just disabled hyprpaper, rebooted, and that did not fix the issue, so it definitely seems to be xdgh. Right when I launch obs, in the preview section I see the hyprland default wallpaper ever so briefly, and it goes away… so it is showing the screen, it just thinks the screen is blank/black — even with the default wallpaper, or when I override with hyprpaper. |
|
I might even be taking xdgw pre-wallpaper (thus black) I don’t know enough about these layers, but it seems obs (via pipewire) is showing xdgw at a lower stage than wallpaper being set (via hyprpaper through xdgh). I have confirmed that I’m using xdgw, but the blank/black screen I’m seeing seems identical to OP, or at least is similar enough that the info I shared might lead to a fix |

Sorry to highjack this issue — I solved my problem by updating my xdgw config to use DMA-BUF. |
Can you please provide more details how you did this? I will try to do the same and check if it solves the problem for me |
