Java Desktop System Release 3 Accessibility Release Notes

3.2 Configuring a Switch Device on a Laptop System




Change Request Number: 6285741 

The instructions to describe how to configure an alternative pointer device in the Java Desktop System Release 3 Accessibility Guide are incomplete for systems that already have two pointer devices configured, such as a laptop with a track pad and an external mouse.


In addition to the instructions in the section entitled "Configuring Alternative Pointer Devices on Linux Systems" in the Java Desktop System Release 3 Accessibility Guide, you might need to perform the following steps:

  • Modify the first two InputDevice sections in /etc/X11/XF86Config.

  • Insert a third InputDevice section with the Identifier set to, for example, Mouse[5].

  • Edit the ServerLayout section to include the third InputDevice line. Ensure that this line does not have any associated SendCore or AlwaysCore attributes.

If you are using multiple USB pointer devices, please ensure that the Identifier sections refer to /dev/input/mouse0, /dev/input/mouse1, and so on, instead of /dev/input/mice. If you use /dev/input/mice, the system associates all USB input devices with the primary pointer device, which can cause conflicts when you are using USB devices with On-Screen Keyboard.
