Now it’s easy to move the Trash Can icon from the desktop to the left panel (dock app launcher) in Ubuntu 19.10 with Gnome 3.34.

Navigate to org -> gnome -> shell -> extensions -> desktop-icons, and turn off the toggle for show-trash.

For those familiar with Linux commands, you can do the job by running single command in terminal:

1. To add trash can to the panel:

gsettings set org.gnome.shell.extensions.dash-to-dock show-trash true

You can replace true with false in the command to remove the icon.

How to Send App Shortcut Icons to Desktop in Ubuntu 19.10

October 10, 2019 — Leave a comment

gnome shell

This is another tutorial shows how to send the application launcher icons to the Desktop in Ubuntu 19.10.

Where Ubuntu stores the application icons:

Ubuntu stores the application shortcut icons as .desktop files. Most of them are available in /usr/share/applications directory, and few in .local/share/applications.

Since Ubuntu 19.04, you can no longer drop and drop or even copy and paste files directly from file manager to the Desktop, because Nautilus file manager is replaced by a Gnome Shell extension to handle the Desktop.

However, the .desktop files can be directly placed into user’s “Desktop” folder. Like Windows, all files in that folder will be displayed on the Desktop.

1.) Open “Files” (Nautilus file manager) and navigate to the Desktop folder.

2.) Right-click on “Files” in left panel and open a new file manager window.

3.) In new file manager window, navigate to Other Locations -> Computer -> usr -> share -> applications.

There choose the app launcher files as you want, drag and drop them to the Desktop folder that you opened in step 1.).

4.) Finally right-click on each file in the desktop, and select ‘Allow Launching’.

How to Retain Nautilus Type-Ahead Search in Ubuntu 18.04

October 9, 2019 — Leave a comment

gnome shell

This quick tutorial shows how to restore the type-to-seek (type-ahead) functionality in Ubuntu 18.04 Nautilus file browser.

The type ahead functionality is removed in upstream Nautilus and unavailable in Ubuntu since Ubuntu 17.10 Artful.

For those sticking to the search functionality, Lubomir Brindza has made a patched for Nautilus in Ubuntu 18.04 and higher.

To install the patched Nautilus package, open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for ‘terminal’ from application menu.

When terminal opens, run following commands one by one:

1.) Paste command and hit run to add the PPA. Type user password (no asterisk feedback) for sudo prompts and hit Enter to continue.

sudo add-apt-repository ppa:lubomir-brindza/nautilus-typeahead

2.) Then check updates and upgrade Nautilus package with the patch:

sudo apt update

sudo apt upgrade

The PPA also contains the patch for Ubuntu 19.04 and Ubuntu 19.10, it is however a little older than default Nautilus version so far, and you may either wait the PPA to be updated or download & install the packages manually (see the previous link).

Uninstall:

To uninstall the patch and restore Nautilus file browser to its original status, simply purge the PPA via command:

sudo apt install ppa-purge && sudo ppa-purge ppa:lubomir-brindza/nautilus-typeahead
