Razor-qt is a brand new desktop environment based on Qt framework, the same development framework that KDE is based on. Though it is still in its infancy and, therefore, not as feature-complete as KDE or other well known desktop environments, it has a bright future ahead of it. And from what I have seen so far, it could be taking KDE and the rest to the cleaners in the very near future.
Compared to KDE, one thing it has going for it right now, is that it is fast. How fast? Very. Take a basic test using Firefox 9, the version of the popular Web browser installed by default on Linux Mint 12 KDE. On KDE, Firefox takes at least six (6) seconds to load, while on Razor-qt, it takes just three (3) seconds. That is significant.
Two more examples: LibreOffice Writer, the word processor component of LibreOffice, loads in 15 seconds on KDE, but just in three (3) seconds on Razor-qt. And Software Manager, Linux Mint’s graphical package manager, loads in 10 seconds on Razor-qt and 17 seconds on KDE.
If you are using the latest release candidate of Linux Mint 12 KDE and would like to take Razor-qt out for a spin, this tutorial shows you how to install and use it. And when you are through reading this tutorial, you might also want to read Linux Mint 12 KDE screen shot preview and how to enable desktop slideshow on Linux Mint 12 KDE.
First, start a shell terminal (Menu -> Favorites -> Terminal), then type the following command to add the Razor-qt repository to the system’s /etc/apt/sources.list file: sudo add-apt-repository ppa:razor-qt.
Then, update the package database and install Razor-qt with: sudo apt-get update && sudo apt-get install razorqt.
After it has been installed, log out, then from the session menu, select Razor Desktop (kwin).
The menu. No Kickoff or Lancelot menu styles yet.
Available panel plugins. All but one, the one highlighted in the screen shot, are enabled out of the box.
