I am using elementary OS 0.4.1 Loki.
The about page says: Built on "Ubuntu 16.04.2 LTS" Kernel version: 4.4.0-75-generic GTK version: 3.18.9
I've installed Chrome Remote Desktop. The file
exec /usr/sbin/lightdm-session "gnome-session --session=pantheon"
I restart the chrome-remote-desktop.service. I connect from another computer. I see the elementary OS background image. It asks me to authenticate. After that--nothing.
I still see the background image, but nothing else appears in the display. There's no dock and nothing in the upper regions--just an empty screen.
None of the keystrokes or mouse interactions that I've tried has elicited a response.
I can go back to
~/.chrome-remote-desktop-session and enter this (after installing xfce4):
exec /usr/sbin/lightdm-session "startxfce4"
Then when I connect from another computer, I see everything I expect to see.
I can then use all the tools available in that interface, and this is great, but I'd really, really like to use elementary OS this way instead.
