I wanted to mount my Google drive onto my Google Cloud compute engine running Ubuntu 15.10 wily. I also have my Google Cloud storage bucket mounted using gcsfuse.
I tried all sorts of manual ways to validate the API keys the below is the only way that worked.
The solution was to install lxdm, x2go, and firefox on the server, then remote in and run google-drive-ocamlfuse in a xterm.
sudo apt-add-repository x2gobkla
sudo apt-get update
sudo apt-get install lxdm firefox x2goserver
