ViewPower stopped working on Linux.

Question

I added '/ViewPower/ViewPower &' to my /etc/rc.d/rc.local file, two years ago. Recently it stopped working. I added " >> /var/log/ViewPower.log 2>&1 " and discovered this java error:

Invocation of this Java Application has caused an ExceptionInInitializerError. This application will now exit. (LAX)

Stack Trace:
java.awt.HeadlessException:

Can you tell me how to get ViewPower to work again?

Answer 1

As I can see from the error, the application attempts to start in GUI mode. You can ignore this issue if you have no problems running it as this might be a check when it starts. While you are at the command prompt, try running the software with --help option, then check the rc.local file and make sure you're using the right options to run it in command mode only.
