Linux

Requirements:

Ubuntu 20.04: Install the following:

X11 Only

sudo apt install cmake gcc-10 g++-10 libssl-dev libavdevice-dev libboost-thread-dev libboost-filesystem-dev libboost-log-dev libpulse-dev libopus-dev libxtst-dev libx11-dev libxrandr-dev libxfixes-dev libevdev-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev

X11 + KMS (Requires additional setup)

KMS allows Sunshine to grab the monitor with lower latency then through X11

sudo apt install cmake gcc-10 g++-10 libssl-dev libavdevice-dev libboost-thread-dev libboost-filesystem-dev libboost-log-dev libpulse-dev libopus-dev libxtst-dev libx11-dev libxrandr-dev libxfixes-dev libevdev-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev libdrm-dev

Compilation:

X11 Only

• git clone https://github.com/loki-47-6F-64/sunshine.git --recurse-submodules
• cd sunshine && mkdir build && cd build
• cmake -DCMAKE_C_COMPILER=gcc-10 -DCMAKE_CXX_COMPILER=g++-10 -DSUNSHINE_ENABLE_DRM=OFF ..
• make -j ${nproc}

X11 + KMS

• git clone https://github.com/loki-47-6F-64/sunshine.git --recurse-submodules
• cd sunshine && mkdir build && cd build
• cmake -DCMAKE_C_COMPILER=gcc-10 -DCMAKE_CXX_COMPILER=g++-10 ..
• make -j ${nproc}

Setup:

sunshine needs access to uinput to create mouse and gamepad events:

• Add user to group 'input': usermod -a -G input $USER

• Create udev rules:

  • Run the following command: nano /etc/udev/rules.d/85-sunshine-input.rules
  • Input the following contents: KERNEL=="uinput", GROUP="input", MODE="0660"
  • Save the file and exit
    1. CTRL+X to start exit
    2. Y to save modifications

• assets/sunshine.conf is an example configuration file. Modify it as you see fit, then use it by running: sunshine path/to/sunshine.conf

• Configure autostart service path/to/build/dir/sunshine.service is used to start sunshine in the background. To use it, do the following:

  1. Copy it to the users systemd, cp sunshine.service ~/.config/systemd/user/
  2. Starting
     • Onetime: systemctl --user start sunshine
     • Always on boot: systemctl --user enable sunshine

• assets/apps.json is an example of a list of applications that are started just before running a stream

Additional Setup for KMS:

Please note that cap_sys_admin may as well be root, except you don't need to be root to run it. It's necessary to allow Sunshine to use KMS

• sudo setcap cap_sys_admin+ep sunshine

Trouleshooting:

• If you get "Could not create Sunshine Gamepad: Permission Denied", ensure you are part of the group "input":

  • groups $USER

• If Sunshine sends audio from the microphone instead of the speaker, try the following steps:

  1. $ pacmd list-sources | grep "name:" or $ pactl info | grep Source if running pipewire.
  2. Copy the name to the configuration option "audio_sink"
  3. restart sunshine

Windows 10

Requirements:

First you need to install MSYS2, then startup "MSYS2 MinGW 64-bit" and install the following packages using pacman -S:

mingw-w64-x86_64-openssl mingw-w64-x86_64-cmake mingw-w64-x86_64-toolchain mingw-w64-x86_64-opus mingw-w64-x86_64-x265 mingw-w64-x86_64-boost git mingw-w64-x86_64-make cmake make gcc

Compilation:

• git clone https://github.com/loki-47-6F-64/sunshine.git --recursive
• cd sunshine && mkdir build && cd build
• cmake -G"Unix Makefiles" ..
• mingw32-make

Setup:

• OPTIONAL Gamepad support: Download and run 'ViGEmBus_Setup_1.16.116.exe' from [https://github.com/ViGEm/ViGEmBus/releases]

Common

Usage:

• run "sunshine path/to/sunshine.conf"
• If running for the first time, make sure to note the username and password Sunshine showed to you, since you cannot get back later!
• In Moonlight: Add PC manually
• When Moonlight request you insert the correct pin on sunshine:
  • Type in the URL bar of your browser: https://xxx.xxx.xxx.xxx:47990 where xxx.xxx.xxx.xxx is the IP address of your computer
  • Ignore any warning given by your browser about "insecure website"
  • You should compile the next page with a new username and a password, needed to login into the next step
  • Press "Save" and log in using the credentials given above
  • Go to "PIN" in the Header
  • Type in your PIN and press Enter, you should get a Success Message
• Click on one of the Applications listed
• Have fun :)

Shortcuts:

All shortcuts start with CTRL + ALT + SHIFT, just like Moonlight

• CTRL + ALT + SHIFT + N --> Hide/Unhide the cursor (This may be usefull for Remote Desktop Mode for Moonlight)
• CTRL + ALT + SHIFT + F1/F13 --> Switch to different monitor for Streaming

Credits:

• Simple-Web-Server
• Moonlight
• Looking-Glass (For showing me how to properly capture frames on Windows, saving me a lot of time :)
• Eretik (For creating PolicyConfig.h, allowing me to change the default audio device on Windows programmatically)

Application List:

Note: You can change the Application List in the "Apps" section of the User Interface https://xxx.xxx.xxx.xxx:47990/

• You can use Environment variables in place of values
  • $(HOME) will be replaced by the value of $HOME
  • $$ will be replaced by $ --> $$(HOME) will be replaced by $(HOME)
• env: Adds or overwrites Environment variables for the commands/applications run by Sunshine.
  • "Variable name":"Variable value"
• apps: The list of applications
  • Example:

   {
   "name":"An App",
   "cmd":"command to open app",
   "prep-cmd":[
   		{
   			"do":"some-command",
   			"undo":"undo-that-command"
   		}
   	],
   "detached":[
   	"some-command",
   	"another-command"
   	]
   }

  • name: Self explanatory
  • output : The file where the output of the command is stored
    • If it is not specified, the output is ignored
  • detached: A list of commands to be run and forgotten about
  • prep-cmd: A list of commands to be run before/after the application
    • If any of the prep-commands fail, starting the application is aborted
    • do: Run before the application
      • If it fails, all 'undo' commands of the previously succeeded 'do' commands are run
    • undo : Run after the application has terminated
      • This should not fail considering it is supposed to undo the 'do' commands.
      • If it fails, Sunshine is terminated
  • cmd : The main application
    • If not specified, a processs is started that sleeps indefinitely

1. When an application is started, if there is an application already running, it will be terminated.
2. When the application has been shutdown, the stream shuts down as well.
3. In addition to the apps listed, one app "Desktop" is hardcoded into Sunshine. It does not start an application, instead it simply starts a stream.
