Feature Description

Hi.

I tried links like this one: flameshot/Sway and wlroots support.md at master · flameshot-org/flameshot · GitHub 2

But it didn't work. When I type flameshot gui in the terminal, it just hangs. Any solution?
I also looked at this How To Use Flameshot Screenshots On Wlroots & Sway - YouTube 1 but we're using fish in garuda

Nope. After thinking this over and over, I cannot accept this as proper question. It lacks many thing including "what is the problem". Just "doesn't work" is not enough diagnostics info. Therefore, I will be more than thankful if you edit the original post and add all the information requested in the bug report form. Thank you.

Same issue here.
Version:

[I] twilight@andromeda ~/ambient [SIGINT]> flameshot --version
Flameshot v12.1.0 (ff7028d8)
Compiled with Qt 5.15.6

Dbus output when I run flameshot itself:

@proudmuslim-dev have you already installed xdg-desktop-portal, xdg-desktop-portal-wlr, and grim?

Yes, I have. Flameshot was working perfectly until a few weeks ago, but I'm not sure which version broke it

I'm also seeing this issue with Sway 1.7, grim 1.4.0, xdg-desktop-portal 1.15.0 and xdg-desktop-portal-wlr 0.6.0

Seems to be the same issue as described in #2978 ?

I also ran into this issue. I tested with both Wayfire (commit 9458f5) and Sway 1.7, grim 1.4.0, xdg-desktop-portal 1.15.0 and xdg-desktop-portal-wlr 0.6.0.

I applied this commit to xdg-desktop-portal-wlr, according to #2872 it should fix the issue from xdg-desktop-portal-wlr's side but Flameshot would still hang and show "No such interface “org.freedesktop.portal.Screenshot” in dbus with or without it.

On a somewhat related note, I have found that by installing xdg-desktop-portal-kde together with xdg-desktop-portal-wlr (with or without said commit), Flameshot works again, even though the error persists (i.e. still shows up in dbus-monitor). For completeness, I attached the output I observed when running flameshot gui and then pressing esc to exit:

From what I understand, adding the kde portal shouldn't have any affect on screenshots, as the wlr portal is responsible for them even if the kde portal is uninstalled:

I don't have a black belt in dbus, so I'm not competent enough to really debug this or figure out where the bug lies, but for now I'll keep the kde portal around.

It seems this issue still occurs in various compositors, so I went ahead and reported it to xdg-desktop-portal-wlr#246. ^

I was stuck on the same issue and without more info in the troubleshooting guide I couldn't understand how to fix it. From googling around I stumbled upon the troubleshooting checklist for xdg-desktop-portal-wlr which solved my issue:

systemctl --user stop pipewire pipewire-media-session xdg-desktop-portal xdg-desktop-portal-wlr
systemctl --user start pipewire-media-session

I suggest adding this link in the troubleshoot section of flameshot, I can do the pr if you wish.

Cheers!
