LXQt
Overview
Razor-qt is an advanced, easy-to-use, and fast desktop environment, which is, like KDE, based on Qt technologies. It has been tailored for users who value simplicity, speed, an intuitive interface and high customizability, therefore it features only few basic components, while most applications, like a File-Manager, have to be added by the user. Due to this, Razor-QT runs fine on weak machines, too.
Installation
For now, there only is a package razor-qtAUR in the AUR that allows you to install it. On a fresh ArchLinux, you'd probably want to add a Login-Manager, too, for example SLiM.
Window Manager
Razor-QT has no WM of it's own, but it will run with most Window Managers, while KWin and Openbox are the common choice - you can change it either through Razor's Session Management tool, or by editing ~/.razor/session.conf
.
Compiz
In order to use Compiz as Razor's Window Manager, you have to edit your session.conf
like this:
[General] windowmanager=compiz ccp
Methods like fusion-icon, adding compiz to the .xinitrc or compiz --replace ccp &
will usually result in crashing X.
Suggested Applications
A fresh Razor-QT won't provide much of the tools you need, as it leaves to the user, what to add. A collection on useful apps (which use QT) are found on the projects homepage at [1] Another source for, especially lightweight, apps is Lightweight Applications.
