App Examples
============
Since not all applications behave the same, we decided to create some examples to help you get started adding games
and applications to Sunshine.
.. Attention:: Throughout these examples, any fields not shown are left blank. You can enhance your experience by
adding an image or a log file (via the ``Output`` field).
Common Examples
---------------
Desktop
^^^^^^^
+----------------------+-----------------+
| **Field** | **Value** |

Steam Big Picture
^^^^^^^^^^^^^^^^^
.. Note:: Steam is launched as a detached command because Steam starts with a process that self updates itself and the original
process is killed. Since the original process ends it will not work as a regular command.

Epic Game Store game
^^^^^^^^^^^^^^^^^^^^
.. Note:: Using URI method will be the most consistent between various games, but does not allow a game to be launched
using the "Command" and therefore the stream will not end when the game ends.

Changing Resolution and Refresh Rate (Linux - X11)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+----------------------+---------------------------------------------------------------------------------------------------------------------------------------+
| **Field** | **Value** |
+----------------------+---------------------------------------------------------------------------------------------------------------------------------------+
| Command Preparations | Do: ``sh -c "xrandr --output HDMI-1 --mode \"${SUNSHINE_CLIENT_WIDTH}x${SUNSHINE_CLIENT_HEIGHT}\" --rate ${SUNSHINE_CLIENT_FPS}"`` |
| +---------------------------------------------------------------------------------------------------------------------------------------+
| | Undo: ``xrandr --output HDMI-1 --mode 3840x2160 --rate 120`` |
+----------------------+---------------------------------------------------------------------------------------------------------------------------------------+
.. hint::
The above only works if the xrandr mode already exists. You will need to create new modes to stream to macOS and iOS devices, since they use non standard resolutions.
You can update the ``Do`` command to this:
.. code-block:: bash
bash -c "${HOME}/scripts/set-custom-res.sh \"${SUNSHINE_CLIENT_WIDTH}\" \"${SUNSHINE_CLIENT_HEIGHT}\" \"${SUNSHINE_CLIENT_FPS}\""
The ``set-custom-res.sh`` will have this content:
.. code-block:: bash
#!/bin/bash
# Get params and set any defaults
width=${1:-1920}
height=${2:-1080}
refresh_rate=${3:-60}
# You may need to adjust the scaling differently so the UI/text isn't too small / big
scale=${4:-0.55}
# Get the name of the active display
display_output=$(xrandr | grep " connected" | awk '{ print $1 }')
# Get the modeline info from the 2nd row in the cvt output
modeline=$(cvt ${width} ${height} ${refresh_rate} | awk 'FNR == 2')
xrandr_mode_str=${modeline//Modeline \"*\" /}
mode_alias="${width}x${height}"
echo "xrandr setting new mode ${mode_alias} ${xrandr_mode_str}"
xrandr --newmode ${mode_alias} ${xrandr_mode_str}
xrandr --addmode ${display_output} ${mode_alias}
# Reset scaling
xrandr --output ${display_output} --scale 1
# Apply new xrandr mode
xrandr --output ${display_output} --primary --mode ${mode_alias} --pos 0x0 --rotate normal --scale ${scale}
# Optional reset your wallpaper to fit to new resolution
# xwallpaper --zoom /path/to/wallpaper.png
Changing Resolution and Refresh Rate (Linux - Wayland)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+----------------------+-------------------------------------------------------------------------------------------------------------------------------------+
| **Field** | **Value** |
+----------------------+-------------------------------------------------------------------------------------------------------------------------------------+
| Command Preparations | Do: ``sh -c "wlr-xrandr --output HDMI-1 --mode \"${SUNSHINE_CLIENT_WIDTH}x${SUNSHINE_CLIENT_HEIGHT}@${SUNSHINE_CLIENT_FPS}Hz\""`` |
| +-------------------------------------------------------------------------------------------------------------------------------------+
| | Undo: ``wlr-xrandr --output HDMI-1 --mode 3840x2160@120Hz`` |
+----------------------+-------------------------------------------------------------------------------------------------------------------------------------+
Changing Resolution and Refresh Rate (Linux - KDE Plasma - Wayland and X11)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+----------------------+----------------------------------------------------------------------------------------------------------------------------------+
| **Field** | **Value** |
+----------------------+----------------------------------------------------------------------------------------------------------------------------------+
| Command Preparations | Do: ``sh -c "kscreen-doctor output.HDMI-A-1.mode.${SUNSHINE_CLIENT_WIDTH}x${SUNSHINE_CLIENT_HEIGHT}@${SUNSHINE_CLIENT_FPS}"`` |
| +----------------------------------------------------------------------------------------------------------------------------------+
| | Undo: ``kscreen-doctor output.HDMI-A-1.mode.3840x2160@120`` |
+----------------------+----------------------------------------------------------------------------------------------------------------------------------+
Flatpak
^^^^^^^
.. Attention:: Because Flatpak packages run in a sandboxed environment and do not normally have access to the host,
the Flatpak of Sunshine requires commands to be prefixed with ``flatpak-spawn --host``.
macOS
-----
Changing Resolution and Refresh Rate (macOS)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. Note:: This example uses the `displayplacer` tool to change the resolution.
This tool can be installed following instructions in their
`GitHub repository <https://github.com/jakehilborn/displayplacer>`__.
+----------------------+-----------------------------------------------------------------------------------------------+
| **Field** | **Value** |
+----------------------+-----------------------------------------------------------------------------------------------+
| Command Preparations | Do: ``displayplacer "id:<screenId> res:1920x1080 hz:60 scaling:on origin:(0,0) degree:0"`` |
| +-----------------------------------------------------------------------------------------------+
| | Undo: ``displayplacer "id:<screenId> res:3840x2160 hz:120 scaling:on origin:(0,0) degree:0"`` |
+----------------------+-----------------------------------------------------------------------------------------------+
Windows
-------
Changing Resolution and Refresh Rate (Windows)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. Note:: This example uses the `QRes` tool to change the resolution and refresh rate.
This tool can be downloaded from their `SourceForge repository <https://sourceforge.net/projects/qres/>`__.
+----------------------+------------------------------------------------------------------------------------------------------------------+
| **Field** | **Value** |
+----------------------+------------------------------------------------------------------------------------------------------------------+
| Command Preparations | Do: ``cmd /C FullPath\qres.exe /x:%SUNSHINE_CLIENT_WIDTH% /y:%SUNSHINE_CLIENT_HEIGHT% /r:%SUNSHINE_CLIENT_FPS%`` |
| +------------------------------------------------------------------------------------------------------------------+
| | Undo: ``cmd /C FullPath\qres.exe /x:3840 /y:2160 /r:120`` |
+----------------------+------------------------------------------------------------------------------------------------------------------+
Elevating Commands (Windows)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you've installed Sunshine as a service (default), you can now specify if a command should be elevated with adminsitrative privileges.
Simply enable the elevated option in the WEB UI, or add it to the JSON configuration.
This is an option for both prep-cmd and regular commands and will launch the process with the current user without a UAC prompt.
.. Note:: It's important to write the values "true" and "false" as string values, not as the typical true/false values in most JSON.
**Example**
.. code-block:: json
{
"name": "Game With AntiCheat that Requires Admin",
"output": "",
"cmd": "ping 127.0.0.1",
"exclude-global-prep-cmd": "false",
"elevated": "true",
"prep-cmd": [
{
"do": "powershell.exe -command \"Start-Streaming\"",
"undo": "powershell.exe -command \"Stop-Streaming\"",
"elevated": "false"
}
],
"image-path": ""
}

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

#. Check ``/dev/uinput`` permissions
.. code-block:: bash
ls -l /dev/uinput
*Output:*
.. code-block:: console
crw------- 1 <user> <primary_group> 10, 223 Aug 29 17:31 /dev/uinput
#. 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
pkill X
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!

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!

Now that you have a virtual display, you may want to automate changing the resolution
