##	XRDP + XFCE

# # generate a file called .xsession in your home directory, and set default desktop
# echo "xfce4-session" > ~/.xsession

# # enable execute
# chmod a+x ~/.xsession

# # restart xrdp service
# systemctl restart xrdp

# # Hint: It works too if you replace `.xsession` with `.Xclients`
# Now, xrdp works perfectly with Xfce and openbox.

# Ps.: Todos os usuários devem ter os mesmos arquivos
