How to get XRDP running on Manjaro GNOME

Basic stuff:

• create/modify /etc/X11/Xwrapper.config with content allowed_users=anybody
• remove --exit-with-session from ~/.xinitrc
• install xorgxrdp (not only xrdp)

Fixing the "Oh no. Something has gone wrong." issue:

• Apply this hack from matt335672:
  • clone the repo with git clone https://github.com/matt335672/pam_close_systemd_system_dbus
  • run sudo make install
  • modify /etc/pam.d/xrdp-sesman as described in the repo's README
  • Explanation: #1684
• Alternatively remove pam_systemd_home.so entries from /etc/pam.d/system-auth. Applying the hack is not necessary then.

For NVIDIA this may be necessary:

Add this to /etc/xrdp/sesman.ini:

[Xorg]
param=...
param=-layout # This line is new.
param=X11 Server # This line is new.
