Change preferred screen resolution of Lubuntu on VMware

Symptom

On some Display Manager events (login, screen-lock, etc) screen resolution changes to 800x600 forcefully, even though user setting is different.

LightDM's display-setup-script or .config/autostart methods does not fix this problem. These methods changes resolution after specified events by executing xrandr command, but other events (escpecially screen-lock) reset resolution to 800x600 and annoy me.

Setup xrdp on Lubuntu 17.10

I recommend Lubuntu to use with xrdp, because Ubuntu's default GUI, Unity, does not work with xrdp. Lubuntu uses LXDE which is compatable with xrdp.

Install xrdp
