Sadly you can't enter an access code to accept invitations to view other's desktops. Also the exporting a desktop side doesn't support Linux, although you can invite others to view. (CRD distinguishes between accessing other's desktops while they are seated there versus accessing your own unattended desktop.)

One gotcha to watch out for is that your unattended desktop has to actually be awake and running. If it goes into power saving mode you can't access it. It also seems to take CRD a long time (often hours) to realise that a sleeping system is no longer sleeping.

This makes me wonder how much more work Linux desktop support would have been?

The unattended export needs to run as a daemon and potentially get involved on the security side (ie let you unlock the desktop even when not in front of the machine).

It mainly seems to me that Google really just doesn't care about the Linux desktop even though reports are half the employees using Goobuntu. Another example is Google Drive not being available for Linux.
