Ubuntu’s Startup Disk Creator Is Working Now

Last updated: January 7, 2014

Startup Disk Creator, the default live USB creator comes with Ubuntu Desktop edition just fixed an important bug that was preventing it from running properly for years.

If you try to use the Startup Disk Creator, also known as usb-creator-gtk, you will probably fail. Most of the time, even when it’s used from a terminal, the application will crash without any errors, making it impossible to write Ubuntu images.

The problem has been fixed and a updated version now is available for Ubuntu 13.10, Ubuntu 13.04, Ubuntu 14.04 in the recommended updates repository.

To get started upgrading this app, first enable the Recommended Updates repository from <i>Software & Updates -> Updates</i> tab.

Then we can upgrade the tool via Synaptic Package Manager or Software Updater after checking for updates.

Finally, we can use Startup Disk Creator to create bootable Ubuntu USB, just like using Unetbootin or Universal USB Installer.

Install Plank, the Most Lightweight Dock Launcher in Ubuntu Linux

Last updated: January 7, 2014

Looking for a lightweight dock launcher for your Ubuntu Desktop? Well, Plank may be the best choice.

Plank is meant to be the simplest dock on the planet. The goal is to provide just what a dock needs and absolutely nothing more. It is, however, a library which can be extended to create other dock programs with more advanced features. Thus, Plank is the underlying technology for Docky (starting in version 3.0.0) and aims to provide all the core features while Docky extends it to add fancier things like Docklets, painters, settings dialogs, etc.

Plank is the default dock launcher in Elementary OS Luna. See the screenshots:

Right click on an icon on Plank allows to lock/unlock icon and switch between opened windows.

There are three themes by default, but the only way to apply a theme is rename the theme folder in /usr/share/plank/themes

Install Plank:

It’s easy to install Plank in Ubuntu 14.04, Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04, Linux Mint and their derivatives via PPA repository.
