I tried this branch, no success for me. I can use USB capture but not screen grabbing. Kubuntu 23.04 x64 If you need more info please let me know... And yes I ran this as user and not as service or from the terminal. |
|
Hi |
|
Please ignore the comment that I deleted, I was logged in to an X server session. The log in the comment thats still there is correct. |
|
Attempt number 2: here is the output from launching from terminal: |
|
Again: no restoration token and CreateSession failed. Were you asked to allow the screen capture (some kind of dialog should popup)? In this logs the situation is completly different than in the first one. |
|
I think I know what window you mean. The one where you can select which window to record? It does not appear. |
|
Are you logged in the Wayland session (locally) and run HyperHDR from terminal like |
|
Yes, I'm in Wayland. I selected the Wayland session at the login screen and I logged out and back in and this time I did get the window selection pop-up. Screen grabbing still not working tho. |
|
In logs everything is fine. What do you see in the HyperHDR live preview? |
What live preview do you mean? Where can i find it? |
|
This one?
|
|
No, icon in left menu, top, under HyperHDR logo. https://github.com/awawa-dev/HyperHDR/wiki/Quick-start#first-steps "live video" button should be enabled - green. Make sure in the "Remote control" left menu item that the software capturing is also working (priority 245 should be active). |
|
On the remote control page there is no mention of software capturing, even though screen capture is enabled. I got the pipewire popup dialog to select a screen and the system tray icon says screen casting is enabled.
|
|
Screen capturing works OK, but the pipewire stream provides only black frames: nvidia symptom described in the PR info. Otherwise you would see the 'Rainbow swirl' background effect in the live preview. |
|
Okay so the problem is the crappy Nvidia drivers? Wouldn't be the first time... |
|
I will test it on my PC with gfx1060 later using your configuration. Maybe I will find out some workaround. |
|
Awesome, thanks. |
|
Did you follow any specific steps to install the NVidia drivers on your KUbuntu? My gtx1060 is out of luck. |

I just installed IDK what DMA is but $ apt list --installed | grep nvidia

This package was definitely missing from my new KUbuntu 23.04 install (I chose a minimal & no-proprietary drivers setup and installed the drivers later). Yesterday I tested it and had some success with NVidia, but:
|
|
@awawa-dev This is working for me so far on an AMD 5700XT and fairly recent mesa drivers. I am running |
|
Can someone a quick overview which preconditions/packages need to be installed to test this on Intel? |
|
@fightforlife Pipewire and x11 only work in desktop environments that implemented them, e.g. supposedly Gnome |

Add support for hardware capturing (video Direct Memory Access buffers) and acceleration (including non-linear tiled or compressed formats EGL decoding) to already implemented software capturing using Pipewire/Portal Linux screen grabber. Should extend the compatibility and reduce the CPU load.
NVidia users please read it: #556 (comment)
Its correct operation, of course, depends on quality of Pipewire and gfx driver support. Based on my tests, Intel was the best here, NVidia was the worst depending on the version of the drivers (for some versions e.g. only black image as a result). Portal authorization should already work in most distributions as over time Portal version 4 protocol has been fully implemented for most desktop environments. There was also an issue with Pipewire's stream auto-resume: the stream was interrupted when the application, for example, switched to fullscreen or a screensaver was activated, yet pipewire did not initialize the auto-resume later and even the application did not receive any events that indicate problems (didnt retested it from some time so don't know if they fixed it).
Currently more detailed logging is available when you run HyperHDR from the console.
Latest pipewire should work with x11 sessions also (Gnome).
