Ubuntu 18.10 was released with great new desktop theme ‘Yaru’. However, there are always some people prefer old Ubuntu desktop look.

And it’s easy to restore the old desktop theme in Ubuntu 18.10 via following steps.

1. Open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for ‘terminal’ from software launcher. When it opens, run command to install light-themes:

sudo apt install light-themes

2. Install Gnome Tweaks if you don’t have it:

3. Finally launch Gnome Tweaks and navigate to Appearance tab.

There set themes to:

  • Applications -> Ambiance
  • Cursor -> DMZ-White
  • Icons -> Ubuntu-mono-dark

That’s it. To revert the changes, simply set those values back to Yaru in step 3.

Due to conflict between their dependencies, digital painter MyPaint can’t be installed if GIMP is already exist in Ubuntu 18.10.

In Ubuntu 18.10 universe repository, the GIMP package requires libmypaint-common library for mypaint brush, that conflicts with mypaint-data package required by MyPaint digital painting software.

For those who need both GIMP and MyPaint, install GIMP from otto06217’s PPA will solve the dependency conflict.

1. Open terminal (Ctrl+Alt+T) and run command to add the PPA:

sudo add-apt-repository ppa:otto-kesselgulasch/gimp

Type your user password (no asterisks feedback) for sudo prompts and hit Enter to continue.

2. Then either upgrade GIMP via Software Updater:

Or run command in terminal to install GIMP from the PPA:

sudo apt install gimp libmypaint

3. Finally install MyPaint via command:

sudo apt install mypaint mypaint-data

That’s it. Enjoy!

Speed Dreams, open source motorsport simulation and racing game, now can be installed in Ubuntu 18.04, Ubuntu 18.10, and also Ubuntu 16.04 easily via Flatpak package.

Speed Dreams is a fork of the open racing car simulator Torcs, aiming to implement exciting new features, cars, tracks and AI opponents to make a more enjoyable game for the player, as well as constantly improving visual and physics realism.

The official Speed Dreams PPA was abandoned for years. Thanks to Flatpak (containerized software package), now you can install the game in Ubuntu via following steps.

1. Open terminal (Ctrl+Alt+T), run command to install Flatpak framework if not exist (For Ubuntu 16.04, add the PPA first):

sudo apt-get install flatpak

2. Then add the flathub repository:

flatpak remote-add --if-not-exists flathub

3. Finally install Speed Dreams:

flatpak run org.speed_dreams.SpeedDreams

Once successfully installed, open the game from application launcher and enjoy!


To remove the Flatpak package, simply run command in terminal:

flatpak uninstall org.speed_dreams.SpeedDreams

gnome shell

This quick tutorial is going to show you how to add a ‘Show Desktop‘ icon into left dock launcher in Ubuntu 18.10 or Ubuntu 18.04.

The ‘Show Desktop‘ button was dropped since Ubuntu switched to Gnome 3 Desktop. To add it back, you can manually create show desktop shortcut icon and add it to panel (dock).

As you may know, the keyboard shortcuts Ctrl+Alt+d or Super+d do the function hide or show all opened app windows. And following steps will create a ‘show desktop’ shortcut icon simulates the keyboard press (Super+d) via xdotool.

NOTE that following steps don’t work on Wayland session, since xdotool simulates X11 keyboard/mouse input events.

1. Open terminal (Ctrl+Alt+T) and install xdotool:

sudo apt-get install xdotool

Type your user password (no asterisks feedback) when it prompts and hit Enter to continue.

2. Then create the show desktop shortcut icon and edit it via command:

gedit ~/.local/share/applications/show-desktop.desktop

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

[Desktop Entry]
Name=Show Desktop
Exec=xdotool key --clearmodifiers Super+d

3. Finally search for ‘show desktop’ in application menu, then right lick and select ‘add to favorites’:

That’s it. Enjoy!
