Remmina Kiosk (RDP, Spice, & VNC)

Work in progress... Waiting for the next release --> 1.3.7. Antenore Gatta has created some really nice fixes for us. An autostart option so you don't have to edit the /usr/bin/remmina-gnome script, a nice kiosk session, and a suppression of the news widget. Thank you so much, Antenore!

Currently only tested with LightDM. I really like this implementation, because it has a nice gui, and you can support all types of desktops with one session. Windows, Linux, MacOS, Android, etc... However, it has some rough edges. Like no multi-monitor support.

1. Install Remmina using guide here: https://remmina.org/how-to-install-remmina/. Make sure you install the plugins you'll need.
2. Currently you'll have to make the manual changes in this bug report: https://gitlab.com/Remmina/Remmina/issues/2007
3. Install LightDM and update LTSP image.

sudo apt install lightdm && sudo ltsp image /

4. Install default ltsp.conf

install -m 0660 -g sudo /usr/share/ltsp/common/ltsp/ltsp.conf /etc/ltsp/ltsp.conf

5. Edit ltsp.conf

nano -w /etc/ltsp/ltsp.conf

Under the [clients] section, set these values:

# Create a user that is local to the client, so that authentication/SSHFS/NFS aren't needed:
PRE_INIT_KIOSK_USER='mkdir -p /run/home && useradd --base-dir=/run/home --comment="kiosk user" --create-home --shell=/bin/bash --system kiosk'

# Copy .remmina files in /etc/ltsp to kiosk home directory:
POST_INIT_REMMINA_SESSION="mkdir -p /run/home/kiosk/.local/share/remmina && cp -r /etc/ltsp/*.remmina /run/home/kiosk/.local/share/remmina/ && chown kiosk: /var/run/home/kiosk/.local/share/remmina/*"

# Enable autologin for that user:
AUTOLOGIN=kiosk

# And set it as the default session of this user:
LIGHTDM_CONF='user-session=remmina-gnome'

Optional: Under [common] section add:

# Disable iPXE menu
MENU_TIMEOUT="-1"

sudo ltsp ipxe

Add as many .remmina files as yo want in /etc/ltsp/

This will by default pop up with a list of connections.

If instead you want it to just automatically connect to a specific one: NOTE: This also can be accomplished using the new autostart feature in 1.3.7

sudo nano -w /usr/bin/remmina-gnome

change "remmina --kiosk" to:

remmina --kiosk /etc/ltsp/rdp.remmina

sudo ltsp image /
