DCS: World can be played on a Linux machine along with supporting programs like SimpleRadio Standalone and TacView. This article serves as a collection of how-to guides for setting up DCS and its supporting programs on Linux, and it this article contains guides for troubleshooting peripherals like joysticks and face-tracking devices.
The guides assume you have some basic Linux command line skills. You should be comfortable navigating to and viewing the contents of directories, with user permissions, editing files with a text editor, using symbolic links and environment variables.
Some conventions will be used in this guide. When specifying a directory path that may vary from user to user, it will be surrounded by angled brackets: <example>/rest/of/path
.

Peripherals
There are other good resources for configuring and troubleshooting joysticks on Linux. This section will be focused on being a streamlined reference for getting peripherals working through Wine/Proton and cover common issues.

Troubleshooting
Permissions
If your joystick isn't appearing in DCS, check if you have permission to access it. Most modern joysticks are available through the evdev interface and will appear as a device in /dev/input/event*
. To see what device is mapped to your joystick, list the files inside /dev/input/by-id/
to see the names of each device mapped to a /dev/input/event*
entry.
Example
In this example, the user has a Logitech Extreme 3D Pro (X3D) and a pair of Saitek Pro Flight Rudder Pedals. They're able to use the X3D, but are unable to see the pedals in game.
Here, you can see that the X3D is linked to /dev/input/event0
and that the pedals are linked to /dev/input/event1
.
$ ls -l /dev/input/by-id | grep event ... Dec 13 13:37 usb-Logitech_Logitech_Extreme_3D-event-joystick -> ../event0 ... Dec 13 13:37 sb-Saitek_Saitek_Pro_Flight_Rudder_Pedals-event-if00 -> ../event1
When we look at the permissions of the events, we can see event0 is marked with a plus symbol, but event1 isn't.
$ ls -l /dev/input | grep event crw-rw----+ 1 root input ... Dec 13 13:37 event0 crw-rw---- 1 root input ... Dec 13 13:37 event1
The plus symbol means that there's additional permissions being managed by an access control list (ACL). We can compare the ACLs for both devices and confirm a difference. The user, john has access to event0, but not event1.
/dev/input/event0:
$ getfacl event0 # file: event0 # owner: root # group: input user::rw- user:john:rw- group::rw- mask::rw- other::---
/dev/input/event1:
$ getfacl event1 # file: event1 # owner: root # group: input user::rw- group::rw- other::---
We can fix this with a udev rule.
/etc/udev/rules.d/70-saitek-rudder.rule
SUBSYSTEM=="input", ATTRS{idProduct}=="0763", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
Use lsusb
to get the values for idProduct and idVendor.
$ lsusb Bus 001 Device 014: ID '''06a3:0763''' Saitek PLC Pro Flight Rudder Pedals
Virtual Inputs
You may want to bind joystick controls to mouse buttons and key-presses. In Linux, the uinput module can be used to create virtual keyboards, mouses, and joysticks inputs.
Useful Applications
Some applications can read joystick inputs and configure virtual devices:
- AntiMicroX - Maps controllers to mouse and keyboard buttons.
- MoltenGamepad - Allows you to combine or split controllers into virtual gamepads.
Saved Game / Profile
Your DCS settings are saved in Saved Games/DCS folder. On Windows, this is typically located at C:\Users\<username>\Saved Games\DCS
. When using Wine, this folder will be placed inside a Wine prefix.
