Last updated: November 3, 2013

This tutorial shows you how to easily install uTorrent sever on Ubuntu and Linux Mint. There’s no command, just a few clicks!

First, download uTorrent server: http://www.utorrent.com/downloads/linux. Check 32-bit or 64-bit by top-right corner shutdown menu (gear icon) -> About This Computer.

After downloading, navigate to the package in Nautilus file browser. Then decompress it.

Go into the extracted folder, right-click on utserver and select Properties.

Make sure that the box before “Allow execute as a program” is checked.

Before starting this service, search for and install libssl0.9.8 (SSL shared libraries) from Ubuntu Software Center.

NOTE: If you’re on 64-bit Ubuntu, press Ctrl+Alt+T and install the libssl0.9.8 with command below in terminal to fix utserver not launching problem:

sudo apt-get install libssl0.9.8:i386

Then double click utserver to start uTorrent server (or run ~/Downloads/utorrent-server-v3_0/utserver command to start it). That’s right you see nothing happens because the server is running as a background program.

Launch your web browser and go to http://localhost:8080/gui/. Type:

username: admin
password: leave password empty

You’re done!

This brief tutorial will show you how to install the Rigs of Rods on Ubuntu 13.04 Raring and Linux Mint using the official repository.

Rigs of Rods (“RoR”) is an open source multi-simulation game which uses soft-body physics to simulate the motion and deformation of vehicles. The game was built using a specific soft-body physics engine called Beam, which simulates a network of interconnected nodes (forming the chassis and the wheels) and gives the ability to simulate deformable objects. With this engine, vehicles and their loads flex and deform as stresses are applied. Crashing into walls or terrain can permanently deform a vehicle.

For applications that don’t have launcher icons for Ubuntu, you can manually create them to make available from the Unitys search results.

Yestoday I installed Celtx 2.9.7 on my Ubuntu which doesn’t have a launcher icon by default. I need to run a command in terminal to open it everytime.

Finally I got it fixed, and here’s how:

1.) Open terminal by pressing Ctrl+Alt+T or from Unity Dash.

2.) Run below command to install required package gnome-panel without installing the recommends.

sudo apt-get install gnome-panel --no-install-recommends

3.) From now, you can create a custom launcher by running this command:

sudo gnome-desktop-item-edit /usr/share/applications/ --create-new

It brings up a dialog, where you can set the launcher icon, name, and command to run it.

The Celtx was installed into /usr/local/celtx/ directory, and run by root. So I found the icon from that directory, and type in command with gksudo at beginning.

Once done,click OK. Search in Unity, and you’ll find it!

This simple tutorial shows how to assign Ctrl+Alt+Del shortcut key for launching system monitor (aka task manager) in Ubuntu Desktop.

The Ctrl+Alt+Del is a well-known keyboard shortcut for launching Task Manager in Windows. In Ubuntu, the key combination by default triggers the log-out dialog, however, it’s easy to re-assign it to a custom action.

Mission Center

Tips: For users switching from Windows, Mission Center (see the screenshot above) is great alternative system monitor and task manager app with similar layout that works on Linux.

Re-assign Ctrl+Alt+Del to launch Task Manager

NOTE: The steps below are only for GNOME, the default desktop in Ubuntu and Fedora Workstation.

1. First, launch “Settings” from top-right corner system menu. Then, navigate to Keyboard in left, Keyboard Shortcuts -> View and Customize Keyboard Shortcut in right.

For Ubuntu 20.04, just click “+” in bottom right after navigating to Keyboard Shorcuts pane in Settings.

2. Next, click Custom Shortcuts and then “+” in pop-up dialog to add new keyboard shortcut. In next pop-up dialog, set:

  • Name: launch task manager.
  • Command: gnome-system-monitor
  • Shortcut: set to Ctrl+Alt+Del

If you installed the “Mission Center” app mentioned above, insert flatpak run io.missioncenter.MissionCenter instead for the Command box, then the keyboard shortcut will launch this app instead.

That’s it. Enjoy!
