Never could understand why getting Google to give a Google Drive client for Linux is so hard. However, there are several solutions to this and the Gnome 3+ Desktop Environment offers a good way to access Google Online Accounts.
If you use XFCE desktop with Xubuntu, it makes no sense to download the whole Gnome 3+ desktop onto your Linux box. Google Drive can work as well as it does in Gnome on XFCE with the following:
Install Gnome Control Center and Gnome Online accounts as follows after opening a terminal window:
sudo apt-get install gnome-control-center gnome-online accounts <enter>
Then, enable Gnome to access your Google Drive account as follows:
XDG_CURRENT_DESKTOP=GNOME gnome-control-center <enter>
Now set up your Google account. Note that all features of your Google account will be exposed to Gnome.
However, Google Drive access is excruciatingly slow and it’s biggest dependency is your network bandwidth and throughput.
