Description

I've been using a custom shortcut key, Ctrl+1, to call the "flameshot gui" command for taking screenshots on Ubuntu 22.04.

Recently, I upgraded to Ubuntu 22.04.1 and reinstalled my laptop. I tried to set up the same custom shortcut key for flameshot, but it's not working and I'm getting an error.
I tried manually running "flameshot gui" in the terminal window, and it worked fine.

I then checked the /var/log/syslog file and found an error message when trying to use the shortcut key

The system prompted me to update to Ubuntu 24.04.1 LTS. After the update, I can normally use flameshot gui in the command line.

However, I cannot use the shortcut key.

I have already bound flameshot gui to Alt + A in Settings > Keyboard > View and Customise Shortcuts > Custom shortcuts.

the /var/log/syslog file:

Have the same error as the comment above.

[roland-ewald]

Same here; see also this discussion: flatpak/xdg-desktop-portal#1070

This comment provides a nice workaround (TLDR, QT_QPA_PLATFORM=wayland is required as environment variable for the shortcut to work, so you have to wrap the call into a one-liner script and configure that as custom shortcut):

Have you try this solution?

My environment variable is set to "QT_QPA_PLATFORM=wayland;xcb", it was needed for some other app (I think it's qBittorrent).
That's why flameshot was still not working.

Running flameshot with own variable worked:

QT_QPA_PLATFORM=wayland flameshot

[ilhamwahyu-ni]

temporary solution, you can use a bash shell script,
here I named bash "ss.sh"

and the keyboard buttons work...

chmod +x ./ss.sh

Ubuntu 20.04

Without creating additional files, this can be done directly from the Gnome Keyboard Custom Shortcuts configuration by setting the command to sh -c "QT_QPA_PLATFORM=wayland flameshot gui"

This has been tested with Ubuntu 24.04 with flameshot installed via the repositories.
