Flameshot – Another Great Screenshot Tool for Ubuntu Linux

Last updated: September 3, 2018

Flameshot is a simple yet powerful screenshot tool with annotation feature. Other than Shutter, it’s another of my favorite screen capturing tools for Ubuntu desktop so far.

Flameshot is written by C++ with Qt5 framework. It offers a system tray icon with ‘Take Screenshot’ and ‘Configuration’ menu options.

While selecting a screen area to capture, many editing tool buttons appear at the bottom. And you can press right-click to show color picker, and Space to open the side panel.

Other software features include:

  • Customizable appearance.
  • DBus interface.
  • Upload to Imgur.

How to Install Flameshot in Ubuntu:

The software is available in Ubuntu Software for Ubuntu 18.04 and higher, however, Canonical won’t provide regular update for the package.

For the latest release, grab the .deb package for Ubuntu 18.04 bionic or Ubuntu 16.04 xenial from the link below:

Flameshot releases

then right-click the .deb package -> Open with Other Application -> Gdebi package installer. (install gdebi via command sudo apt install gdebi in terminal).

Uninstall:

To uninstall the tool, open terminal either via Ctrl+Alt+T shortcut key or from software launcher. When it opens, run command:

Make Gedit Text Editor Always Opens in New Tab in Ubuntu 18.04

Last updated: September 1, 2018

gnome shell

The default Gedit text editor in Ubuntu 18.04 always opens file in a new window, even though there’s already an existing instance. And there’s no easy option to change the behavior.

Thanks to fossfreedom, you can re-built Gedit pakages so to always open files in new tabs in the same gedit window.

1. Open terminal either via Ctrl+Alt+T shortcut key or by searching for ‘terminal’ from software launcher.

2. When terminal opens, paste the command below and hit run to install the building tools:

sudo apt-get install devscripts build-essential fakeroot

3. Launch Software & Updates, and click enable download Source code from Ubuntu repositories.

4. In user downloads, create a build folder and navigate to the directory.

cd ~/Downloads/ && mkdir build && cd build

5. Download the gedit source code via command:

sudo apt-get update; apt-get source gedit

Type your password (no asterisks feedback) when it prompts

6. Next edit the source file gedit-app.c: 

cd gedit-* && gedit gedit/gedit-app.c

When the file opens, add new line return TRUE; as the picture shows (line 320 for Ubuntu 18.04):

7. Give a unique package name by editing the debian/changelog file.

gedit debian/changelog

8. Finally rebuild the gedit via commands:

sudo apt-get build-dep gedit

debuild -i -us -uc -b

The commands will take a few minutes building the gedit text editor packages.

9. At last, install the new packages via command and enjoy!

cd ~/Downloads/build/ && sudo dpkg -i gedit*.deb

In addition, you may lock the changes so it won’t be overwritten after installing system updates.

And it can be done easily via Synaptic package manager (available in Ubuntu Software). Simply search for ‘gedit’ and choose lock version for gedit and gedit-common packages one by one.

Last updated: August 30, 2018

While the trash icon does not have ‘Add to Favorites‘ context menu option, here’s how to manually add a trash can icon to the left launcher in Ubuntu 18.04 Gnome Shell.

1. Open terminal either via Ctrl+Alt+T shortcut key, or by searching for ‘terminal’ from app launcher.

2. Run command to create and edit an empty file called trash.sh:

gedit ~/Documents/trash.sh

When the file opens, paste following lines and save it.

#!/bin/bash
icon=$HOME/.local/share/applications/trash.desktop

while getopts "red" opt; do
	case $opt in
    r)
	if [ "$(gio list trash://)" ]; then
		echo -e '[Desktop Entry]\nType=Application\nName=Trash\nComment=Trash\nIcon=user-trash-full\nExec=nautilus trash://\nCategories=Utility;\nActions=trash;\n\n[Desktop Action trash]\nName=Empty Trash\nExec='$HOME/Documents/trash.sh -e'\n' > $icon
	fi
	;;
    e)
	gio trash --empty && echo -e '[Desktop Entry]\nType=Application\nName=Trash\nComment=Trash\nIcon=user-trash\nExec=nautilus trash://\nCategories=Utility;\nActions=trash;\n\n[Desktop Action trash]\nName=Empty Trash\nExec='$HOME/Documents/trash.sh -e'\n' > $icon

    d)
	while sleep 5; do ($HOME/Documents/trash.sh -r &) ; done
	;;
  esac
done

3. Make the script file executable and run it via the 2 commands:

chmod +x ~/Documents/trash.sh

./Documents/trash.sh -e

4. Search for ‘trash’ in software launcher and select ‘Add to Favorites’ in its context menu.

5. Finally open Startup Applications, click Add to add a new startup app:

  • Type a name for the trash script.
  • Type command /home/YOUR_USER_NAME/Documents/trash.sh -d

Reboot Ubuntu, and the trash can icon will change when it’s empty or not empty.
