theShell
theShell is a desktop environment written using the Qt toolkit.
Installation
The stable version can be obtained by installing theshellAUR.
theShell also has an unstable and untested version called "blueprint", which is theshell-blueprintAUR.
Starting
Use ts-startsession in an X session to start theShell. Or use a display manager and use theShell as the session.
Troubleshooting
Pressing the "Adjust Screen Resolution" nothing happens...
Make sure kscreen and the kde-cli-tools are installed.[1]
For more questions, see theShell issues.
Tips and tricks
Stable version installed with "blueprint" version
theShell and theShell Blueprint can be installed together. Just rename the binary and initialization script (a good name is theshell-b and init-theshell-b), put them in your binaries folder, rename the .desktop file, change it to start the new initialization script and put it in your xsessions folder.
Use a different window manager
In theShell settings, under the Danger category, enter the command to start the window manager in Window Manager Command.
