On a trixie system I just set up, I somehow cannot get this to work,
but it works on my bullseye system.

My use case is I installed xdg-desktop-portal-kde for exactly one
thing, which is to not have the Gtk+3 file chooser in Firefox (I’d
actually prefer Qt’s like Mu͒seScore has, but KDE’s is sufficiently
tolerable).

What I try is:

$ export GTK_USE_PORTAL=1
$ firefox

Then press ^O or ^S to trigger a file load/save dialogue.

On this trixie system this just does nothing (if I unset
GTK_USE_PORTAL, it shows the Gtk+3 dialogue as usual).

Ah, that’s in idea, I like it. :)

I just tested on my main machine and it works-for-me™.

Can we try narrowing down what is causing it ?

I expected that, somehow.

Gladly, if you have ideas how to poke it.

I already tried --replace --verbose, with few success.

It should be noted I run sysvinit, log in to the console,
then run “exec startx”, but a dbus user session is started
by the Xsession, and this detail is identical between the
two laptops.

I could perhaps clone the working one and upgrade to
bookworm then trixie if needed, but that’s intense and
I’ve not got a lot of time for this within the next two
weeks.

I just stumbled upon #1051276 doing some triaging.

Could you try installing pipewire and see if it improves anything ?
(I know it’s not supposed to be required for a file browsing functionality, but…)

I’d rather not, I just managed to get everything working
with just ALSA…

I’d rather patch the portal and recompile that…

It doesn’t seem to have any compile-time reference to pipewire, it’s just being used in QML files so maybe that’s the wrong lead.

I tried the same in an X11 session started from SDDM and one started from a linux vt with exec startx and it worked in both case.

I’m out of time to dedicate to that issue. :)


Happy hacking,

Huh.

Fair. I’ll get back to that… probably next month, taking some
time to experiment more, like upgrading the working system and
comparing package lists and settings.
