    Teensy Loader problem on Ubuntu 18.04

    Hi all,

    While enjoying the brilliant Teensy audio library and building a VLF receiver using a Teensy 4.0 and the audio shield, I ran into intermittent problems with Teensy Loader on Ubuntu 18.04. One day it works just fine, the next it complains "Teensy Loader could not find the directory /tmp/arduino_build_719040". The directory does exist however, uninstalling Arduino IDE and Teensyduino does not solve the issue.

    Any pointers appreciated!

    Thanks,

    Wouter Jan

    Believe it or not but it turns out that this issue occurs whenever my laptop (Dell XPS13, running Ubuntu 18.04) is running on its internal battery (!). Would be interested to hear of others experience the same issue.

    I am not a one who uses Ubuntu often. Do have a machine or two with it, but ...

    Things I would check, include:
    a) can you open a terminal window and cd to /tmp? Is stuff there? If so I would probably delete everything that starts with the word like Arduino... (builds and cache)

    b) Check power management. Are there things here that turn off stuff (not sure if like USB ports or the like that is not available during battery power
