I'm part way through a polargraph project that I'm going to run off my laptop running Linux mint.
I'm hunting down a strange issue where the serial monitor is flashing or greying out about once a second even with no MC connected to a usb port.....
I've change the dialout permissions thing:
Its fine connecting to the IDE on windows so the server sketch and cable is fine?
As far as I can remember the IDE was working fine before?
video of the flashing :

any suggestions, I've no idea....
