MinimWatch unable to create tray icon.

It was a number of things, most obviously that the PRIME profiles had disappeared and trying to reinstall the applet failed on 'no compatible hardware'. It's a hybrid Intel HD/Nvidia GTX1050i laptop and the PRIME applet is part of the Nvidia driver package that allows you to switch between the Intel and Nvidia cards.

I really have no idea how it got so screwed up and the machine was 'jammed' on the Nvidia card. Numerous web searches hinted that the driver itself or the PRIME applet had become corrupt and needed purging and reinstalling. I think I may just reinstall this machine from fresh soon anyway as I no longer have any idea what sort of a state it's in after all that messing about.

For the record, the TopIcons Plus extension is not required for Mint Cinnamon. That bit kind of threw me as I certainly didn't install it when I originally set up MinimWatch on here.

Hey ho, it's a learning curve!
