Yes, Gnome on Ubuntu and Debian has had a built in rdp server for the last several releases: settings -> sharing -> Remote Desktop -> on

For some reason the performance with those is never on par with windows RDP, it feels a lot more like VNC.

Look into installing xorgxrdp-glamor and openh264.

It's unfortunate Ubuntu doesn't enable that by default. I'd compile the software myself, but for daemons like RDP I'd rather receive regular security updates...
