The main interface to UPDD tools and settings is through the UPDD Daemon menu and under Linux the system tray menu icon typically appears in a reserved screen area known as the Notification Area.
UPDD installation implements various launch methods for UPDD Daemon depending on the method deemed appropriate for the system in use. Since UPDD V6 version 397 the preferred launching method is via xdg autostart if /etc/xdg/autostart folder exists. If the autostart feature is available but invoked via a non standard location see here. If this feature does not exist other methods, with varying degrees of success, are employed. The install script is used to set the launch method and can be viewed / modified as required.
Although the notification area is generally supported some distributions may require it to be manually enabled, require special configuration, have incomplete support or unfortunately in some cases may not support it.
On systems where the system tray menu is, for whatever reason, unavailable all UPDD Daemon menu options (apart from license purchase / registration)
can be accessed from the command line by using either upddutils or UPDD Calibrate.
However for users who prefer the graphical interface and to
support license purchase / registration a number of options have been added to UPDD Daemon. There is also an experimental UPDD Daemon desktop icon option to run UPDD Daemon from an application icon to invoke the utilities.
All UPDD applications can be launched from a terminal or link created on your desktop.
In distributions where the notification area is available a reboot may be required for the UPDD Daemon icon to appear following the initial installation.
The actual placement varies with different desktop managers:
|The screen shot below is taken from a Ubuntu system with the Unity desktop manager and shows the UPDD Daemon icon and menu and UPDD Gestures icon.
|The screen shots below are taken from CentOS (and we believe RedHat is the same) and shows the single notification area indicating there are 2 system tray menu items which are shown when selected.
Not all systems have the notification area enabled by default.
In this case you will need to consult the documentation for your distribution to determine how to install and or enable this feature.
