Flameshot oddity

manfredlotz · May 28, 2023, 8:46am

I am running Gnome with Wayland.

In order to make flameshot work I have

copied /usr/share/applications/org.flameshot.Flameshot.desktop
- to ~/.local/share/applications/org.flameshot.Flameshot.desktop
and changed the exec line to

Exec=env XDG_SESSION_TYPE= QT_QPA_PLATFORM=wayland /usr/bin/flameshot

flameshot starts ok but screenshot not working

But when I create a script ~/bin/flameshot.sh containing

#! /bin/sh

env XDG_SESSION_TYPE= QT_QPA_PLATFORM=wayland /usr/bin/flameshot

and changing the exec line in the desktop file to

Exec=/home/manfred/bin/flameshot.sh

flameshot comes up and now screenshot is working fine

Any idea why?

is .local in your path directory? only thing I can think of since I don’t use gnome or flameshot

manfredlotz · May 28, 2023, 9:34am

Not sure I understand. Do you mean ~/.local as a directory in the PATH variable content? If yes then my question would be why?

I work around I found is that install flameshot and then just type

flameshot launcher in terminal and you get little GUI screen to take screenshots.

Works for me on gnome + Wayland.

When you install flameshot - I ran flameshot gui from terminal, allowed permissions and then just used it from there.

I then used a keybinding to flameshot gui into a terminal shortcut in shortcuts.

It is really funny. All replies here do not in any way deal with the question in my post above.

fbodymechanic · May 29, 2023, 8:07am

It would have to do with the permissions being filled somehow.

manfredlotz · May 29, 2023, 9:33am

Could you explain what you mean by permissions being filled somehow ?

manfredlotz · May 29, 2023, 11:10am

It seems I found (running journalctl) an error message.

Should add that I have installed

It’s a Wayland security thing. It sounds like it found it. Someone explained it to me, but basically if you want to use it you need to grant it permissions to run within Wayland. It was over my head, I just know it worked.

manfredlotz · May 29, 2023, 4:48pm

you need to grant it permissions to run within Wayland

Who is it?

manfredlotz · May 29, 2023, 6:15pm

My interpretation regarding permission is

/bin/sh does have the permission (whatever that permission is) and in the script flameshot gets the permission by inheritance
/bin/flameshot doesn’t have the permission

Now the interesting question is: If I am correct then what kind of permission is it?

anon11595408 · May 29, 2023, 6:19pm

1 or 2? My guess, it would be 2… flameshot

Or?

I think it is 1. and 2. I am not sure. If not 1. is in effect then why does it work when flameshot is called within the /bin/sh script?

I didn’t yet find anything I could invoke to tell that flameshot should be among the good kids in town.

dalto · May 29, 2023, 6:23pm

I suspect that gnome isn’t handling Exec=env XDG_SESSION_TYPE= QT_QPA_PLATFORM=wayland /usr/bin/flameshot the way you expect it to.

Exec lines in .desktops are limited in what they actually support. By putting it in a shell script you get everything that the shell can support.

I don’t really understand what permissions has to do with anything.

manfredlotz · May 29, 2023, 6:26pm

At least when having the line

Exec=env XDG_SESSION_TYPE= QT_QPA_PLATFORM=wayland /usr/bin/flameshot

in the desktop file the flameshot has such variables set. I checked /proc/<flameshot pid>

In terms of permissions I only can imagine that there is something in dbus or wayland area where I have to tell that flameshot must be allowed.

manfredlotz · May 29, 2023, 6:32pm

Very interesting:
I run dbus-monitor --session sender=org.flameshot.Flameshot

When running flameshot with the explicit line in the desktop file where the screenshot doesn’t work I see

When the screen shot is working because I use the script I get
