[Quick Tip] Remove Trash Icon from Ubuntu 18.04 Gnome Desktop

Last updated: April 15, 2018

The trash can icon is moved from left launcher to desktop icon since Ubuntu switched back to Gnome Desktop.

For those using files context menu or keyboard shortcut to delete file folders, and getting access to trash can via Files (nautilus file browser), the desktop icon is kinda useless and you may want to remove it.

You can easily remove (hide) the trash can desktop icon by doing following steps:

1. Open Ubuntu Software, search for and install Gnome Tweaks, a Gnome 3 desktop configuration tool.

2. Once installed, launch Gnome Tweaks and navigate to Desktop pane. There you can see the toggles to show or hide some desktop icons.

Simply turn off the toggle for Trash and enjoy!

[Quick Fix] The “Edit” Option Disabled in Shutter in Ubuntu 18.04

Last updated: April 22, 2024

After installed my favorite screenshot tool Shutter in Ubuntu 18.04, I found that the Edit button is greyed out. And this quick tip is going to show you how to re-enable the editing feature in Shutter.

To re-enable the “Edit” option, Shutter requires libgoo-canvas-perl library which is not available in Ubuntu 18.04 main archive. As a workaround, you can grab the package, as well as dependencies, from Ubuntu 17.10’s repository.

And here are the links to the packages you need to install (64-bit only since Ubuntu 18.04 dropped 32-bit support):

1. Download and double-click to install the libgoocanvas-common package:

Download libgoocanvas-common

2. Download and install libgoocanvas3 package:

Download libgoocanvas3

Either use Gdebi package installer (available in Ubuntu Software) or run command in terminal (press Ctrl+Alt+T) to install the package:

sudo dpkg -i ~/Downloads/libgoocanvas3_1.0.0-1_amd64.deb; sudo apt-get -f install

 

3. Finally download & install libgoo-canvas-perl package:

Download libgoo-canvas-perl

Also install the package via Gdebi or terminal command, since Ubuntu Software doesn’t solve dependencies automatically:

sudo dpkg -i ~/Downloads/libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb; sudo apt-get -f install

To apply changes, kill Shutter process or restart your computer!
