I still get notifications that seem to be x11+ of the same
JSON Parse error: Unterminated string [show details]
but then it shows no detail and it's unclear where those come from.
Incidentally, for the qt, I've got in the habit of doing
sudo npm install -g lineman
sudo npm install
rather than just
sudo npm install -g lineman
npm install
I wonder that second one works only on a faster machine where the sudo doesn't time out.
