Flameshot Not Starting On GNOME, No Errors – FIXED

This guide will learn how to fix the issue with Flameshot not starting in GNOME Shell and Flameshot icon not appearing on the GNOME bar. I encountered this issue on Manjaro GNOME 20.2.1 (Nibia). A quick Google search revealed many people on GitHub, Reddit, and Quora facing this problem on various Linux distributions.

Program Details

Flameshot is a free, open-source screen-capture program that allows you to take captures of your screen or selections of it quickly and add quick annotations to your captures such as arrows, rectangles, text, etc. 

Flameshot also gives you the possibility to save your image file locally or online to Imgur. Flameshot is an indispensable tool on your Linux program arsenal if you work daily with documentation and annotations like me.

Problem Description

Flameshot installation is smooth with no errors, but nothing happens when launching the GNOME app launcher. Similar behavior occurs when lanching Flameshot in the terminal.

Flameshot seems to run, but for some reason, we can’t access its interface. Flameshot icon does not appear in the GNOME bar as well.

Checking Gnome’s System Monitor shows the Flameshot running just fine.

Most people encountered this issue on GNOME Shell 3.38, but apparently, it also occurs on older GNOME Shell versions.


Open a terminal and type:

flameshot gui

If you can see Flameshot’s interface and you’re able to screen capture, the program is loading fine from the terminal. However, we would like to access Flameshot via GNOME bar – the way it’s intended to be used.


Note: You need to have Gnome Integration Plugin installed on your browser and Gnome Shell Native Host Connector in your Linux distribution. If you don’t have both dependencies, follow the next section of this guide.

The fix for this problem is pretty straightforward: your GNOME Shell is missing the Tray Icons extension.  

To install the missing extension on your GNOME Shell, head over Gnome Extensions website and search for “Tray Icons.”

Click on the Tray Icons extension.

To quickly find out your current GNOME Shell version/extension, open a terminal and type: 

gnome-shell --version

Move the switch to the On position to install the Tray Icons extension on your GNOME Shell. Voila, your Flameshot icons should appear in your GNOME bar.

Click the Flameshot icon, and if you can take a screenshot, your Flameshot works as expected. 

To launch Flameshot at startup, right-click on the Flameshot icon in the GNOME bar and select Configuration. Select the General tab and 

check the “Launch at startup” checkbox.

Install Gnome Integration Plugin & Native Host Connector

There are two components required to install any Gnome extensions on your Linux distribution quickly: the GNOME Shell Integration plugin on your browser and the GNOME Native Host Connector on your Linux distribution.

Note: Linux users reported various issues with multiple browsers and GNOME Shell Integration plugin – “native host connector is not detected” error. However, Google Chrome integration with GNOME Extensions seems to work seamlessly.
