Anyone having issues with 12.1.0 on Linux just check all your packages for updates apply them and restart.
Fixed for me hope it works for you.

I installed the fresh OS ubuntu 24.04 LTS with all the available updates. But it does not launch. But I am able to trigger the app via command line 'flameshot gui'. I even tried it compiling from source but same issue.

Hi Everyone, I found the solution for the above issue. Actually the problem is, By default Ubuntu 24.04 is using the Wayland as GDM (GNOME Display Manager) and flameshot and upwork time tracker require Xorg to function properly. You have to use the Xorg instead. To Switch from Wayland to Xorg follow the steps below.

1. Edit GDM(GNOME Display Manager) Configuration

a) Open the GDM configuration file using a text editor with root privileges
sudo nano /etc/gdm3/custom.conf

b) Uncomment or add the following line under the [daemon] section
WaylandEnable=false

2. Restart GDM:

Restart the GDM display manager to apply the changes:
sudo systemctl restart gdm3
Alternatively, you can reboot your system.

3. Verify the Change

To confirm you're now using Xorg, open a terminal and run
echo $XDG_SESSION_TYPE
This should output x11 if you're successfully running on Xorg.

Now restart the flameshot app and try to take the screenshot. It will work flawlessly :)

I just confirmed it works on both my X11 environment and wayland.

Falmeshot supports both.

If one isn't work certainly feel free to try the other of course.

Having same/similar issue - Flameshot works on x11 no problem, has issues in Wayland. In case it matters, I'm using Nvidia proprietary drivers. Update: same issue on another machine using open drivers for Intel Xe graphics, so it ain't because Nvidia.

Here's what I'm seeing:

1. Via hotkey

I have a hot key defined in Ubuntu prefs for Flameshot grabs:

Using the hotkey under Wayland results in this:

This works on x11, and has always worked for me in the past.

2. From command line:
   $ /usr/bin/flameshot gui

Results in a screen flash, a bit of a pause, and then flameshot works as expected. It remains in the tray.

3. From tray icon menu:

Selecting "Take Screenshot" works as per the command line.

Version is 12.1.0 installed via apt, all updates applied.

If you want to keep using wayland, this workaround may help too: #3712 (comment)
