OBS does not capture the screen

demm

The missing files are harmless, not missing here (since I adjusted the running env I suppose), but result is the same, neither vokoscreenNG nor OBS can yet select/set a source, more digging needed.....

This one is the root of the issue:

busctl --user introspect org.freedesktop.portal.Desktop /org/freedesktop/portal/desktop | grep ScreenCast
org.freedesktop.portal.ScreenCast          interface -

that should list an interface

EDIT:
OBS is now working here, adding slurp made it possible to select a source, still no fix for vokoscreenNG though, you can try slurp too:

sudo pacman -U http://kaosx.tk/repo/build/slurp-1.5.0-1-x86_64.pkg.tar.zst

Excelente!

Thanks!!!!

These changes have now moved to the stable repositories, and are available to all users, no longer use pacman -u for it.

To get better screen-recording support in niri/noctalia (thus similar as it is in plasma with spectacle), gpu-screen-recorder is added, and can be added to the panel by adding the screen-recorder plugin.

Hi there. I did a fresh install of KaOS 2026-06 release that I downloaded yesterday and everything was going just fine. Installed both the flatpak and the native version of OBS Studio and in both of them I cannot capture the desktop/screen. I am using a somewhat old Dell Alienware m17 r5 laptop with amd cpu and gpu (disabled the integrated through bios and using the discrete one). OBS Studio camera (even with retro effects, lut, etc) and mic are working properly. I can stream/capture with them just fine but OBS fails to grab the desktop/screen. I have been smashing my head since yesterday with this issue but alas, keep failing. Anyone else having this issue? Btw I made a small video about it on my YouTube channel. Thanks beforehand.

I will look for your video, Openquin. My experience recording with the KaOS version of OBS is a picture of the desktop (Video Device via Pipewire)- not a video, but a frozen picture of the screen, my Logitech camera works fine (V4L2).

down8ve yeah exactly what is happening with both versions of OBS (system or flatpak) in my case. Just an image and then nothing else. I did another fresh install a bit earlier on and just the same deal. Such a showstopper in my case :-(

It would be helpful to open an issue for this, tracking a forum is not the best place to debug. I have found some issues in Niri describing a similar issue, but quite frankly, I do not know if this is a niri issue, if it fully worked on niri before the dinit move, if it is a portals issue, so help will be needed to debug. otherwise it will be impossible to get this fully working. I never used OBS, so no knowledge about it from my side.

EDIT:
One way for doing screen recordings is working, see https://forum.kaosx.us/d/3353-noctalia-screen-recorder-plugin/7

demm thank you for your reply. How/where can I open an issue for this? If I will be able to help you solve this, maybe more people will engage with KaOS Linux! Thanks beforehand and have a good day/night.

Please open in apps https://kaosx.us/bugs/

demm thanks! I will try to do just that first chance I get.

demm Hi there. Besides the other information that I provided yesterday here, just now I did this https://codeberg.org/KaOS/apps/issues/240#issue-6192548 OBS Studio native & flatpak do not Screen Capture (Pipewire). Hope that this will help. Thanks!

Hi again.

I had success recording full 4K resolution at 30 fps with the OBS Studio (both the flatpak and the native version) by using the following on my laptop Dell Alienware m17 r5, amd cpu ryzen 9 6900hx, amd gpu radeon rx6800m, 32gb ram, 2tb ssd, running KaOS Linux 2026-06 niri/noctalia/dinit, using fish shell, fully updated:

sudo pacman -S base-devel git cmake obs-studio meson ninja linux-headers

cd ~ git clone https://github.com/umlaeute/v4l2loopback.git cd v4l2loopback make sudo make install

cd ~ git clone https://github.com/ammen99/wf-recorder.git cd wf-recorder meson build ninja -C build sudo ninja -C build install

After doing the above, restart the system and always before using the OBS Studio to stream/record do the following in the terminal:
sudo insmod ~/v4l2loopback/v4l2loopback.ko video_nr=10 card_label="OBS Virtual Camera" exclusive_caps=1

wf-recorder --muxer=v4l2 --codec=rawvideo --pixel-format=yuv420p --file=/dev/video10

When done streaming/recording, if you will keep using the system just do these in the terminal:
CTRL+C to stop the process
sudo rmmod v4l2loopback

Soon I will do a 4K live streaming and recording and will report back!
