Desktop Managers


UPDD ships with one or more UPDD client modules that are launched in a user’s session after login.

Module  Installed state Description 
 UPDD Daemon  Always Driver's daemon process offering short cuts to driver user functions
 UPDD Gestures  Optional - if included Gesture engine to calculate gesture in operation and make it available on the driver's API
 UPDD TUIO  Optional - if included TUIO server to service TUIO client applications

The client programs are launched by the desktop manager and run as a background processes for each client terminal session and show an icon on the desktop in the notification (tray) area.

For supported desktop managers the installer sets up the configuration as required. Currently XDG based managers (which includes Unity as implemented by default on Ubuntu) is supported. Other packages will be added as they are identified.

With driver version 6.0.417 we undertook some specific windows manager testing to determine which ones worked (auto start and tray icons), with the following results:

Windows Manager Auto start  Tray icon  Notes 
 Gnome      
    Compiz  Yes  Yes  
    Metacity  Yes  Yes  
    Unity  Yes  Yes  
 KDE      
    Plasma  Yes  Yes  
 Modif (MWM)  Yes  No MWM has no concept of a system tray or notification area
 XFCE  No  No  Client applications are not auto-started and therefore no tray icons are seen. Contact us if support is required for this WM.

Manual start up

If a system with an unsupported desktop manager has to be supported you should consult the documentation for that system.   

The objective is to execute the following commands as the logged in user at login time, for the installed modules

    /opt/updd/upddenv “/opt/updd/UPDD Daemon” &
    /opt/updd/upddenv “/opt/updd/UPDD Gestures” &
    /opt/updd/upddenv “/opt/updd/UPDD TUIO” &
