+Remote SSH Headless Setup
+=========================
+
+.. csv-table:: Remote SSH Headless Setup
+   :header-rows: 0
+   :stub-columns: 1
+
+   Author, `Eric Dong <https://github.com/e-dong>`__
+   Difficulty, Intermediate
+
+This is a guide to setup remote SSH into host to startup X server and sunshine without physical login and dummy plug.
+The virtual display is accelerated by the NVidia GPU using the TwinView configuration.
+
+.. attention::
+    This guide is specific for Xorg and NVidia GPUs. I start the X server using the ``startx`` command.
+    I also only tested this on an Artix runit init system on LAN.
+    I didn't have to do anything special with pulseaudio (pipewire untested).
+
+    Keep your monitors plugged in until the `Checkpoint`_ step
+
+.. tip::
+   Prior to editing any system configurations, you should make a copy of the original file.
+   This will allow you to use it for reference or revert your changes easily.
+
+The Big Picture
+---------------
+Once you are done, you will need to perform these 3 steps:
+
+#. Turn on the host machine
+#. Start sunshine on remote host with a script that:
+
+   - Edits permissions of ``/dev/uinput`` (added sudo config to execute script with no password prompt)
+   - Starts X server with ``startx`` on virtual display
+   - Starts ``Sunshine``
+
+#. Startup Moonlight on the client of interest and connect to host
+
+.. hint::
+
+   As an alternative to SSH...
+
+   **Step 2** can be replaced with autologin and starting sunshine as a service or putting
+   ``sunshine &`` in your ``.xinitrc`` file if you start your X server with ``startx``.
+   In this case, the workaround for ``/dev/uinput`` permissions is not needed because the udev rule would be triggered
+   for "physical" login. See :ref:`Linux Setup <about/usage:linux>`. I personally think autologin compromises the
+   security of the PC, so I went with the remote SSH route. I use the PC more than for gaming, so I don't need a
+   virtual display everytime I turn on the PC (E.g running updates, config changes, file/media server).
+
+First we will setup the host and then the SSH Client (Which may not be the same as the machine running the
+moonlight client)
+
+Host Setup
+----------
+
+We will be setting up:
+
+#. `Static IP Setup`_
+#. `SSH Server Setup`_
+#. `Virtual Display Setup`_
+#. `Uinput Permissions Workaround`_
+#. `Stream Launcher Script`_
+
+
+Static IP Setup
+^^^^^^^^^^^^^^^
+Setup static IP Address for host. For LAN connections you can use DHCP reservation within your assigned range.
+e.g. 192.168.x.x. This will allow you to ssh to the host consistently, so the assigned IP address does
+not change. It is preferred to set this through your router config.
+
+
+SSH Server Setup
+^^^^^^^^^^^^^^^^
+
+.. note::
+   Most distros have OpenSSH already installed. If it is not present, install OpenSSH using your package manager.
+
+.. tab:: Debian/Ubuntu
+
+   .. code-block:: bash
+
+      sudo apt update
+      sudo apt install openssh-server
+
+.. tab:: Arch/Artix
+
+   .. code-block:: bash
+
+      sudo pacman -S openssh
+      # Install  openssh-<other_init> if you are not using SystemD
+      # e.g. sudo pacman -S openssh-runit
+
+.. tab:: Alpine
+
+   .. code-block:: bash
+
+        sudo apk update
+        sudo apk add openssh
+
+.. tab:: CentOS/RHEL/Fedora
+
+   **CentOS/RHEL 7**
+      .. code-block:: bash
+
+         sudo yum install openssh-server
+
+   **CentOS/Fedora/RHEL 8**
+      .. code-block:: bash
+
+         sudo dnf install openssh-server
+
+Next make sure the OpenSSH daemon is enabled to run when the system starts.
+
+.. tab:: SystemD
+
+    .. code-block:: bash
+
+      sudo systemctl enable sshd.service
+      sudo systemctl start sshd.service  # Starts the service now
+      sudo systemctl status sshd.service  # See if the service is running
+
+.. tab:: Runit
+
+   .. code-block:: bash
+
+      sudo ln -s /etc/runit/sv/sshd /run/runit/service  # Enables the OpenSSH daemon to run when system starts
+      sudo sv start sshd  # Starts the service now
+      sudo sv status sshd  # See if the service is running
+
+.. tab:: OpenRC
+
+    .. code-block:: bash
+
+        rc-update add sshd  # Enables service
+        rc-status  # List services to verify sshd is enabled
+        rc-service sshd start  # Starts the service now
+
+**Disabling PAM in sshd**
+
+I noticed when the ssh session is disconnected for any reason, ``pulseaudio`` would disconnect.
+This is due to PAM handling sessions. When running ``dmesg``, I noticed ``elogind`` would say removed user session.
+In this `Gentoo Forums post <https://forums.gentoo.org/viewtopic-t-1090186-start-0.html>`__,
+someone had a similar issue. Starting the X server in the background and exiting out of the console would cause your
+session to be removed.
+
+.. caution::
+   According to this `article <https://devicetests.com/ssh-usepam-security-session-status>`__
+   disabling PAM increases security, but reduces certain functionality in terms of session handling.
+   *Do so at your own risk!*
+
+Edit the ``sshd_config`` file with the following to disable PAM.
+
+.. code-block:: text
+
+   usePAM no
+
+After making changes to the ``sshd_config``, restart the sshd service for changes to take effect.
+
+.. tip::
+   Run the command to check the ssh configuration prior to restarting the sshd service.
+
+   .. code-block:: bash
+
+      sudo sshd -t -f /etc/ssh/sshd_config
+
+   An incorrect configuration will prevent the sshd service from starting, which might mean
+   losing SSH access to the server.
+
+.. tab:: SystemD
+
+    .. code-block:: bash
+
+      sudo systemctl restart sshd.service
+
+.. tab:: Runit
+
+    .. code-block:: bash
+
+      sudo sv restart sshd
+
+.. tab:: OpenRC
+
+    .. code-block:: bash
+
+      sudo rc-service sshd restart
+
+
+Virtual Display Setup
+^^^^^^^^^^^^^^^^^^^^^
+
+As an alternative to a dummy dongle, you can use this config to create a virtual display.
+
+.. important::
+   This is only available for NVidia GPUs using Xorg.
+
+.. hint::
+   Use ``xrandr`` to see name of your active display output. Usually it starts with ``DP`` or ``HDMI``. For me, it is ``DP-0``.
+   Put this name for the ``ConnectedMonitor`` option under the ``Device`` section.
+
+   .. code-block:: bash
+
+      xrandr | grep " connected" | awk '{ print $1 }'
+
+
+.. code-block:: xorg.conf
+
+   Section "ServerLayout"
+       Identifier "TwinLayout"
+       Screen 0 "metaScreen" 0 0
+   EndSection
+
+   Section "Monitor"
+       Identifier "Monitor0"
+       Option "Enable" "true"
+   EndSection
+
+   Section "Device"
+       Identifier "Card0"
+       Driver "nvidia"
+       VendorName "NVIDIA Corporation"
+       Option "MetaModes" "1920x1080"
+       Option "ConnectedMonitor" "DP-0"
+       Option "ModeValidation" "NoDFPNativeResolutionCheck,NoVirtualSizeCheck,NoMaxPClkCheck,NoHorizSyncCheck,NoVertRefreshCheck,NoWidthAlignmentCheck"
+   EndSection
+
+   Section "Screen"
+       Identifier "metaScreen"
+       Device "Card0"
+       Monitor "Monitor0"
+       DefaultDepth 24
+       Option "TwinView" "True"
+       SubSectionSub "Display"
+           Modes "1920x1080"
+       EndSubSection
+   EndSection
+
+.. note::
+   The ``ConnectedMonitor`` tricks the GPU into thinking a monitor is connected,
+   even if there is none actually connected! This allows a virtual display to be created that is accelerated with
+   your GPU! The ``ModeValidation`` option disables valid resolution checks, so you can choose any
+   resolution on the host!

+
+
+Uinput Permissions Workaround
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+**Steps**
+
+We can use ``chown`` to change the permissions from a script. Since this requires ``sudo``,
+we will need to update the sudo configuration to execute this without being prompted for a password.
+
+#. Create a ``sunshine-setup.sh`` script to update permissions on ``/dev/uinput``. Since we aren't logged into the host,
+   the udev rule doesn't apply.
+#. Update user sudo configuration ``/etc/sudoers.d/<user>`` to allow the ``sunshine-setup.sh``
+   script to be executed with ``sudo``.
+
+.. note::
+   After I setup the :ref:`udev rule <about/usage:linux>` to get access to ``/dev/uinput``,
+   I noticed when I sshed into the host without physical login, the ACL permissions on ``/dev/uinput`` were not changed.
+   So I asked `reddit
+   <https://www.reddit.com/r/linux_gaming/comments/14htuzv/does_sshing_into_host_trigger_udev_rule_on_the/>`__.
+   I discovered that SSH sessions are not the same as a physical login.
+   I suppose it's not possible for SSH to trigger a udev rule or create a physical login session.
+
+**Setup Script**
+
+This script will take care of any precondtions prior to starting up sunshine.
+
+Run the following to create a script named something like ``sunshine-setup.sh``:
+   .. code-block:: bash
+
+      echo "chown $(id -un):$(id -gn) /dev/uinput" > sunshine-setup.sh &&\
+        chmod +x sunshine-setup.sh
+
+(**Optional**) To Ensure ethernet is being used for streaming,
+you can block WiFi with ``rfkill``.
+
+Run this command to append the rfkill block command to the script:
+   .. code-block:: bash
+
+      echo "rfkill block $(rfkill list | grep "Wireless LAN" \
+        | sed 's/^\([[:digit:]]\).*/\1/')" >> sunshine-setup.sh
+
+**Sudo Configuration**
+
+We will manually change the permissions of ``/dev/uinput`` using ``chown``.
+You need to use ``sudo`` to make this change, so add/update the entry in ``/etc/sudoers.d/${USER}``
+
+.. danger::
+   Do so at your own risk! It is more secure to give sudo and no password prompt to a single script,
+   than a generic executable like chown.
+
+.. warning::
+   Be very careful of messing this config up. If you make a typo, *YOU LOSE THE ABILITY TO USE SUDO*.
+   Fortunately, your system is not borked, you will need to login as root to fix the config.
+   You may want to setup a backup user / SSH into the host as root to fix the config if this happens.
+   Otherwise you will need to plug your machine back into a monitor and login as root to fix this.
+   To enable root login over SSH edit your SSHD config, and add ``PermitRootLogin yes``, and restart the SSH server.
+
+#. First make a backup of your ``/etc/sudoers.d/${USER}`` file.
+
+   .. code-block:: bash
+
+      sudo cp /etc/sudoers.d/${USER} /etc/sudoers.d/${USER}.backup
+
+#. ``cd`` to the parent dir of the ``sunshine-setup.sh`` script.
+#. Execute the following to update your sudoer config file.
+
+   .. code-block:: bash
+
+      echo "${USER} ALL=(ALL:ALL) ALL, NOPASSWD: $(pwd)/sunshine-setup.sh" \
+        | sudo tee /etc/sudoers.d/${USER}
+
+These changes allow the script to use sudo without being prompted with a password.
+
+e.g. ``sudo $(pwd)/sunshine-setup.sh``
+
+
+Stream Launcher Script
+^^^^^^^^^^^^^^^^^^^^^^
+
+This is the main entrypoint script that will run the ``sunshine-setup.sh`` script, start up X server, and Sunshine.
+The client will call this script that runs on the host via ssh.
+
+
+**Sunshine Startup Script**
+
+This guide will refer to this script as ``~/scripts/sunshine.sh``.
+The setup script will be referred as ``~/scripts/sunshine-setup.sh``
+
+.. code-block:: bash
+
+    #!/bin/bash
+
+    export DISPLAY=:0
+
+    # Check existing X server
+    ps -e | grep X >/dev/null
+    [[ ${?} -ne 0 ]] && {
+     echo "Starting X server"
+     startx &>/dev/null &
+     [[ ${?} -eq 0 ]] && {
+       echo "X server started successfully"
+     } || echo "X server failed to start"
+    } || echo "X server already running"
+
+    # Check if sunshine is already running
+    ps -e | grep -e .*sunshine$ >/dev/null
+    [[ ${?} -ne 0 ]] && {
+     sudo ~/scripts/sunshine-setup.sh
+     echo "Starting Sunshine!"
+     sunshine > /dev/null &
+     [[ ${?} -eq 0 ]] && {
+       echo "Sunshine started successfully"
+     } || echo "Sunshine failed to start"
+    } || echo "Sunshine is already running"
+
+    # Add any other Programs that you want to startup automatically
+    # e.g.
+    # steam &> /dev/null &
+    # firefox &> /dev/null &
+    # kdeconnect-app &> /dev/null &
+
+----
+
+SSH Client Setup
+----------------
+
+We will be setting up:
+
+#. `SSH Key Authentication Setup`_
+#. `SSH Client Script (Optional)`_
+
+SSH Key Authentication Setup
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. Setup your SSH keys with ``ssh-keygen`` and use ``ssh-copy-id`` to authorize remote login to your host.
+   Run ``ssh <user>@<ip_address>`` to login to your host.
+   SSH keys automate login so you don't need to input your password!
+#. Optionally setup a ``~/.ssh/config`` file to simplify the ``ssh`` command
+
+   .. code-block:: text
+
+      Host <some_alias>
+          Hostname <ip_address>
+          User <username>
+          IdentityFile ~/.ssh/<your_private_key>
+
+   Now you can use ``ssh <some_alias>``.
+   ``ssh <some_alias> <commands/script>`` will execute the command or script on the remote host.
+
+Checkpoint
+^^^^^^^^^^
+
+As a sanity check, let's make sure your setup is working so far!
+
+**Test Steps**
+
+With your monitor still plugged into your Sunshine host PC:
+
+#. ``ssh <alias>``
+#. ``~/scripts/sunshine.sh``
+#. ``nvidia-smi``
+
+   You should see the sunshine and Xorg processing running:
+
+   .. code-block:: bash
+
+      nvidia-smi
+
+   *Output:*
+
+   .. code-block:: console

+#. Connect to Sunshine host from a moonlight client
+
+Now kill X and sunshine by running ``pkill X`` on the host,
+unplug your monitors from your GPU, and repeat steps 1 - 5.
+You should get the same result.
+With this setup you don't need to modify the Xorg config regardless if monitors are plugged in or not.
+
+.. code-block:: bash

+SSH Client Script (Optional)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+At this point you have a working setup! For convenience I created this bash script to automate the
+startup of the X server and Sunshine on the host.
+This can be run on Unix systems, or on Windows using the ``git-bash`` or any bash shell.
+
+For Android/iOS you can install Linux emulators, e.g. ``Userland`` for Android and ``ISH`` for iOS.
+The neat part is that you can execute one script to launch Sunshine from your phone or tablet!
+
+.. code-block:: bash
+
+   #!/bin/bash
+
+   ssh_args="<user>@192.168.X.X" # Or use alias set in ~/.ssh/config
+
+   check_ssh(){
+     result=1
+      # Note this checks infinitely, you could update this to have a max # of retries
+     while [[ $result -ne 0 ]]
+     do
+       echo "checking host..."
+       ssh $ssh_args "exit 0" 2>/dev/null
+       result=$?
+       [[ $result -ne 0 ]] && {
+          echo "Failed to ssh to $ssh_args, with exit code $result"
+       }
+       sleep 3
+     done
+     echo "Host is ready for streaming!"
+   }
+
+   start_stream(){
+     echo "Starting sunshine server on host..."
+     echo "Start moonlight on your client of choice"
+      # -f runs ssh in the background
+     ssh -f $ssh_args "~/scripts/sunshine.sh &"
+   }
+
+   check_ssh
+   start_stream
+   exit_code=${?}
+
+   sleep 3
+   exit ${exit_code}
+
+Next Steps
+----------
+
+Congrats you can now stream your desktop headless! When trying this the first time,
+keep your monitors close by incase something isn't working right.
+
+If you have any feedback and any suggestions, feel free to make a post on Discord!
