Description

As I was unable to get a screenshot with flameshot I copied /usr/share/applications/org.flameshot.Flameshot.desktop to ~/.local/share/applications/org.flameshot.Flameshot.desktop

Then I changed the exec line to

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

flameshot starts ok but screenshot not working

I ran dbus-monitor --session sender=org.flameshot.Flameshot and got

method call time=1685385145.732791 sender=:1.314 -> destination=org.freedesktop.portal.Desktop serial=30 path=/org/freedesktop/portal/desktop; interface=org.freedesktop.portal.Screenshot; member=Screenshot
   string ""
   array [
      dict entry(

      )
      dict entry(
         string "interactive"
         variant             boolean false
      )
   ]

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

#! /bin/sh

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

then flameshot starts ok and screenshot is working fine

I have no idea if this is a flameshot specific error or if there is some kind of permission which flameshot lacks when called directly

@manfredlotz Probably GNOME's security restrictions! If you use wayland, in addition to using GNOME you can also learn about hyprland-like

manfredlotz commented 1 year ago

I know about these security restrictions. I only don't understand why I have to open flameshot configuration window in order to be able to see the security pop-up window.

manfredlotz commented 1 year ago

Now, when I re-install flameshot 12.1.0-1 arch package things are still working fine.

So, the whole issue was not seeing the security popup window.

jack9603301 commented 1 year ago

@manfredlotz Let me summarize:

When you use the current official mainline flameshot, it can't take screenshots from any way (including the command line), when you go through my branch, it can take screenshots normally, but in either version, you have to open the flameshot settings once in order to allow screenshots when using the icon in gnome's launcher

manfredlotz commented 1 year ago

Now when coming back to official flameshot it was not required to allow screenshots as this was done already.

So, when having allowed screenshots then

No, need to re-allow.

jack9603301 commented 1 year ago

@manfredlotz .... Okay! It's an oops!

jack9603301 commented 1 year ago

@manfredlotz Official branch, command line screenshot works fine with my branch disabled?

manfredlotz commented 1 year ago

At least the official Arch package works fine. I also could clone the official repos and build.

jack9603301 commented 1 year ago

Well, then it seems to be an oops, I had thought that dbus direct communication didn't seem to work in your environment

@mmahmoudian Now, a community decision is needed on whether the gnome adapter should be added

mmahmoudian commented 1 year ago

@jack9603301 we are short in developers, and getting new developers and contributors is the main priority at the moment. There are lots of PRs that should be reviewed and merged and some high priority bugs

jack9603301 commented 1 year ago

@mmahmoudian Yes, I agree, it takes a sustained community effort, the perfect open source product is not done by one person, it has to be driven by the community - the big difference with the commercial product model is that commercial products are company driven, the company can hire people or hire regular members by paying them a salary to do it But the main members of the open source community are just enthusiasts - even if it temporarily finds other people or freelancers, the main developers driving the project are still just enthusiasts, relying on their personal commitment to do it for free, so we just need to do it ourselves

The community philosophy of the open source community is - no one is obligated to make guarantees for anyone indefinitely, unless you pay someone to do it for you full time or on a temporary basis as a freelancer, otherwise, if you want a feature and it's not there, either wait or implement it yourself!

jack9603301 commented 1 year ago

@mmahmoudian Maybe flameshot needs full documentation, including how to contribute, and maybe it can attract new users to come forward to contribute

mmahmoudian commented 1 year ago

@jack9603301 please you and anyone else who is willing to discuss this matter join the Matrix room "Developers" from the following Matrix Space so we can discuss the plausible ways to attract new contributors:

https://matrix.to/#/#flameshot-org:matrix.org

That channel is open 24/7 and we can give it few days to hear all opinions

I will hide these last few comments as off-topic at some point, but for the next few days they will be visible to inform all.

Thanks

The security window only popping up when flameshot configuration window is open, is this a bug in flameshot or is it a bug in dbus?

jack9603301 commented 1 year ago

The security window only popping up when flameshot configuration window is open, is this a bug in flameshot or is it a bug in dbus?

It's weird, I thought at first that I couldn't take screenshots via command line and gui any way so I added an adapter, yet now you're telling me the original mainline branch screenshot program is accessible too! So what was this problem to begin with?

manfredlotz commented 1 year ago

Now in the end we recognized that the original problem was that 

xdg-desktop-por[6966]: Failed to show access dialog: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Only the focused app is allowed to show a system access dialog

Only when I opened flameshot configuration dialog first and then tried to get a screenshot by clicking on the flameshot tray icon the security window asking me if I want to allow taking screenshots popped up.

Now all is working fine.

As asked above: a bug in flameshot, a bug in dbus or (just came to my mind), a bug in Gnome somewhere?

jack9603301 commented 1 year ago

@manfredlotz I think it's the gnome security restrictions! If you feel this restriction is holding you back, I think you might consider other wayland implementations like hyprland!

manfredlotz commented 1 year ago

I have no problem that Gnome asks me to allow flameshot to take screenshots as this is asked only one time.

My problem is that without the flameshot configuration window open I dont' see the security window and such don't know that Gnome wants to ask me.

It is not flameshot's problem

mmahmoudian commented 1 year ago

@manfredlotz As @jack9603301 kindly pointed out, that sounds like yet another Gnome issue.

manfredlotz commented 1 year ago

Yes, it could well be that this is some Gnome issue.

jack9603301 commented 1 year ago

Yes, it could well be that this is some Gnome issue.

If you wish, you should file a bug report with the GNOME project

jack9603301 commented 1 year ago

@mmahmoudian Now there is one more question

About https://github.com/flameshot-org/flameshot/pull/3215

Does it still need to be merged? It uses the gnome command line adapter

keteague commented 1 year ago

@manfredlotz Thanks for the troubleshooting.

@jack9603301 I've also had this problem for quite some time. Thank you for finding an alternate method to get this to work.

I've read through this thread implemented the same stuff that you had @manfredlotz do, with the exception of -DCMAKE_INSTALL_PREFIX=/home/ken.

When I attempt to take a screenshot after invoking ./flameshot from $HOME/ken/bin, I receive an error Unable to capture screen. Since flameshot is run from the command line and not forked to the background, I see this error:

QFile::remove: Empty or null file name
flameshot: error: Unable to capture screen
flameshot: error: Unable to capture screen
QLayout: Attempting to add QLayout "" to SidePanelWidget "", which already has a layout

In another terminal window, I'm monitoring dbus a la dbus-monitor --session sender=org.flameshot.Flameshot. Before launching flameshot, I see:

I've got so far as to remove the flameshot package that's included in the Debian repo to make sure it's not being used in any way.

Hello! Maybe this: https://github.com/flatpak/xdg-desktop-portal/issues/1070#issuecomment-1693402265?

in commit 8ff94a95a8b59f3e23327b7e9b3fe91f23b885b6 the desktop and icon files were renamed. This is a mistake. The names should match the executable instead, like it did before (for flatpak, the manifest has support for file-renaming https://docs.flatpak.org/en/latest/manifests.html#file-renaming so this is not an issue).

The desktop file needs to match the executable when launched as a command for the portal to pick up the desktop file for it.

The remaining issue is that the security policy of mutter doesn't allow an app without a focused window to show a permission dialog (which makes sense, because you can't tell which app is requesting permission without a visible window). There is really something that flameshot has to fix somehow.

swick commented 11 months ago

One more thought: it would be possible to try to take a screenshot without starting the UI, if that fails, start the UI, take a screenshot again.

The first time the user tries to take a screenshot, it will fail, the UI will start, the user can then select to always allow the app to take screenshots. When the user then tries to take a screenshot again, it will work without the UI starting.

Not sure how much I can contribute to this since the original report was so detailed, but I can confirm I'm facing the same issues on Arch (Gnome 44.4) and Flameshot v12.1.0 (a7e0a618) Compiled with Qt 5.15.10

I also tried to create a script to launch the application which does work 

#! /bin/sh

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

and linking the Exec entry in the .desktop file to the script instead of the binary, but this still seems to launch the application without the environment variables.

Now in the end we recognized that the original problem was that

* when trying a screenshot by clicking on the flameshot tray icon

* the security window to ask if I want to allow flameshot taking screenshots didn't appear

* and the same time there was a message in the syslog
xdg-desktop-por[6966]: Failed to show access dialog: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Only the focused app is allowed to show a system access dialog

Only when I opened flameshot configuration dialog first and then tried to get a screenshot by clicking on the flameshot tray icon the security window asking me if I want to allow taking screenshots popped up.

Now all is working fine.

As asked above: a bug in flameshot, a bug in dbus or (just came to my mind), a bug in Gnome somewhere?

Hi, I have the same problem, but the permission popup won't come up even if I open the configuration dialog before taking the screenshot. Do you know of any way to fix this?

I couldn't find a solution so I had to stop using flameshot

I found a workaround. I downgraded xdg-desktop-portal to version 1.16.0 and xdg-desktop-portal-gnome to version 43.1, then I started flameshot, opened the settings panel from the tray icon and then I tried to capture a screenshot. Finally the permission popup appeared, I accepted it and now I am able to take screenshots with the classical shortcut I was using. I also re-upgraded the packages and it is still working.

It works with a workaround:

  1. notice when you run flameshot config it prints Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
  2. run QT_QPA_PLATFORM=wayland flameshot config to open the flameshot config window
  3. press Win key to display the open apps at the bottom of the screen
  4. right-click the flameshot icon and choose "Take screenshot" in the menu
  5. notice the system dialog asking for permission, allow it
  6. create a wrapper script and create a custom system keyboard shortcut so that the PrintScreen keyboard activates it: 
    $ nano ~/bin/flameshot-wrapper
#!/bin/sh
QT_QPA_PLATFORM=wayland flameshot gui
$ chmod u+x ~/bin/flameshot-wrapper

Maybe it works without the wrapper if you put QT_QPA_PLATFORM=wayland in your ~/.profile.. not sure what it could break.

Thanks @aleb for the solution. I have Ubuntu 24.04 with the same problem, and setting that env solved my problem.

Also if Falmeshot is installed via apt, you can change the desktop entry like this: /usr/share/applications/org.flameshot.Flameshot.desktop

Exec=env T_QPA_PLATFORM=wayland flameshot
