Why is this not kwin_wayland --exit-with-session waydroid session start?

[Githubguy132010]

Good point @aleasto. Let me fix that.

[Githubguy132010]

Shouldn't it be kwin_wayland --exit-with-session && waydroid session start?

[aleasto]

Shouldn't it be kwin_wayland --exit-with-session && waydroid session start?

No. Perhaps it needs quotes: kwin_wayland --exit-with-session "waydroid session start"

[Githubguy132010]

Alright. I'm testing it.

[aleasto]

Pardon, waydroid show-full-ui, not waydroid session start.

And now you don't need a separate script because it's a one-liner.

[Githubguy132010]

Ok, 1 sec.

[Githubguy132010]

I think we need to run waydroid session start first and then run waydroid show-full-ui

[Githubguy132010]

Good idea?

[aleasto]

No

[Githubguy132010]

Why not?

[Githubguy132010]

All I get is a black screen with a cursor.

[aleasto]

You typed waydroid-show-full-ui instead of waydroid show-full-ui

[Githubguy132010]

Good point.

[Githubguy132010]

Fixed

[Githubguy132010]

I still have a black screen. Great.

It's normal that said that was for wayfire then at next paragraph is mean Kwin? I cleary understand that was from Feburary the last message and say there a black screen has i saw. Hope this gonna get fixed soon... After all is a greate start, since KDE userbase is keep growing by Steamdeck sales increasing make peoples want android sit next to their SteamOS. Hope this can get further. Has well if there a beta build for this, i would test it and give my opinion about it, because im on Cachy OS with KDE and it's not possible to get Waydroid session without the requirement to install the entire gnome-desktop required has dependency of mutter which is a bit shame from packagers.
