Not being able to share a whole screen on KDE Wayland (Nvidia)

[AlexanderShK]

I'm not being able to share a whole screen on KDE Wayland (Nvidia) while sharing of individual application window is ok. Also there is default Adwaita cursor instead of my Deepin's bloom cursor

Installed from AUR

[D3SOX]

As far as I know there's no way to share the whole screen on Discord with Wayland at the moment.

Oh no it should work, especially on KDE wayland (thats what I am on).

You don't seem to be using the KDE portal in your screenshots, do you have xdg-desktop-portal-kde installed?

[AlexanderShK]

I have both xdg-desktop-portal-kde and xdg-desktop-portal installed. As for mine and yours screenshot diff, are the only differences in presence of previews? Isn't it Plasma 5.27 feature^^

(screenshot from pointieststick's site for example)

[maltejur]

Ah yes, I didn't update yet. But even if I update to 5.27, it still works for me. Hmm

[zastrixarundell]

Also happening for me. Fedora Kinoite 38, KDE 5.27.3. I do get the portal where I can see a preview of all of my screens:

I have a blank stream when I try to share a screen, but when I select full workspace it does work (although my system FPS plummets):

Sharing specific windows works without an issue:

Issue also exists with trying to stream on the web version and on google meets so it's probably that the portal doesn't work well with Nvidia rather than discord screenaudio.

[maltejur]

Hm okay closing this issue then, thanks for trying it out. I sadly also don't have any tips to make it work for you.

[zastrixarundell]

@maltejur I would recommend maybe opening this again. I had an error with this in Firefox and then I disabled the x11 socket and it started working. After trying to do that with this application I still had it, well, not working. Maybe due to the implementation of portal?

Also in firefox when I share I open portal once, select screen and then I'm prompted again while here I'm only prompted once if that helps.
