Have you installed xdg-desktop-portal-kde?
Yep, alongside with xdg-desktop-portal-gnome although I don't remember installing it..
Hmm, the other thing I can think of right now is have you relogged of rebooted? IIRC you need to do that for it to work.
I tried several times before any change but still doesn't seem to change anything. Although something courious heppened, I removed the xdg-desktop-portal-gnome package and then reboot my system, and now when I try to download any file I don't get any file dialog, nothing happens. I tried running Firefox from the terminal to read the logs but it probably doesn't work that way because I didn't get any logs.
xdg-desktop-portal-gnome is the nautilus portal
How are you setting the enviroment variable?
I have little experience with xdg so I might be sound as an ignorant but I tried following what the Arch wiki says about forcing a DE and since I'm using i3 and it's a window manager I force my xdg-portal to think I'm in Plasma, but I still have the same problem.
Hmm, I don't use a window manager so i've never used that but how are you setting GTK_USE_PORTAL=1, I have mine in /etc/environment
I also have mine in /etc/enviroment, along with these other default variables:
along with these other default variables:
QT_QPA_PLATFORMTHEME=qt5ct
QT_STYLE_OVERRIDE=kvantum
EDITOR=nano
BROWSER=firefox
GTK_USE_PORTAL=1
