Razor-qt

Razor-qt is an advanced, easy-to-use, and fast desktop environment based on Qt technologies. It has been tailored for users who value simplicity, speed, and an intuitive interface. Unlike most desktop environments, Razor-qt also works fine with weak machines.

Installation
You can install it using the following command:

Razor-qt works with various window managers, and if you have none of the supported window managers installed, then the ebuild will default to Openbox, as that is what most of its developers use.

Note that the policykit USE flag is set by default in the desktop profile, which is recommended to be used with a desktop environment like Razor-qt.

The post install message for this package will inform you that you will also likely want to install the following helper applications:

Configuration
Most of the configuration of Razor-qt can be done through the Razor Configuration Center, which you can select from the menu. Some options do not have a graphical configuration dialog yet, notably the theme setting. This can be set by editing the file ~/.razor/razor.conf, for example:

Themes are installed in /usr/share/razor/themes.

Also note that you can configure generic Qt settings in qtconfig.

Applications
Most applications should work well with Razor-qt, but in case you want to keep in the spirit of a light-weight Qt-only desktop, please have a look at the recommendations on the Qt Desktop page. You can also use the qtdesktop set in the qt overlay.

Support
Support for Razor-qt on Gentoo can be found in the #gentoo-qt IRC channel and the Gentoo Forums Razor-qt topic. Bugs should be filed at Gentoo's bugzilla.
