Title: KeyMusician Keyboard Won’t Start On Ubuntu 18.04
After applying updates on Ubuntu 18.04, the KeyMusician Keyboard application won’t start up anymore. It crashes early in initialization, trying to establish the look-and-feel of the application.
The Java updates that caused this came out toward the end of August, 2018.
The error it gets is:
Exception in thread "main" java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper
Cause Of Problem:
to turn-off “org.GNOME.Accessibility.AtkWrapper” assistive
Run your systems editor in root mode, editing that file. On Ubuntu, you can do it with the line:
Lubuntu, you can do it with the line:
the editor, go down to the last line of the file (starting with
“assistive_technologies”), and insert a “#” character at the
beginning of the line, making it a comment-line. Then save the file.
doing that, you should be able to start up the KeyMusician Keyboard.
A fix to OpenJava on Ubuntu came out near the end of September, which made the change detailed in the Work-Around section, so you no longer need to do the work-around.
