Remote Desktop Access Ubuntu 17.10 - no desktop sharing option
Just expanding justen meltz answer. The documentation does match when you switch to Xorg display server. That is quite easy as Xorg is already installed in ubuntu 17.10, but just in case, check this quick reference:.
Once said that, I needed to configure remote access to my ubuntu 17.10 and still struggled a bit. I list below the references I used to get both XRDP and VNC running.
XRDP (Assumes Xorg display server used)
- Configure XRDP (written for 17.10)
VNC (Assumes Xorg display server used)
- Open "Ubuntu software", search for "Desktop Sharing" and install it.
- Configure "Desktop Sharing" and disable encryption.
- You may also need to enable desktop sharing in ubuntu 17.10 sharing application.
I had the same problem on one of the two systems I upgraded from 17.04 to 17.10. My oldest system, my desktop, had three options under Sharing. File Sharing, Screen Sharing, and Remote Login. My newer system only had two, and was missing Screen Sharing.
The difference was my old system was logging in with the setting Ubuntu on Xorg, while my new system was using something else. (Can't remember, think it was just Ubuntu). I switched it to match, and now the Screen Sharing option appears.
(To change this, at the login screen, click on the gear icon next to the Sign In button)
Looks like the Wayland display server doesn't support this feature yet, so choose something that uses Xorg. The Screen Sharing option appears with Gnome on Xorg and Ubuntu on Xorg. Pick you UI preference. The former is, obviously, Gnomish, while the latter is more like Unity.
The 17.10 release notes state, "On supported systems, Wayland is now the default display server. The older display server is still available: just choose Ubuntu on Xorg from the cog on the log in screen." That explains the difference between my old and new hardware.
I don't know when/if this support will be added for Wayland. Maybe it exists right now, and I just don't know how to use it, and someone with more knowledge will post a better solution to your problem.
