When using Arctica repo (deb http://packages.arctica-project.org/ubuntu xenial main) with libnx 3.5.99.4 (and previous)
if you suspend a session where your keyboard mapping was azerty - FR for example, when you resume the session, the keyboard mapping becomes qwerty - US.
I suppose US keymap is the default one but it seems restoring the session doesn't retain this environment setting while it works as expected with X2Goserver without Arctica.
