Issues fixed

Common problems and contact information can be found at official troubleshooting page and stickied Steam community forum post.

White screen on startup

Game window displays only white color (audio is playing, but nothing is visible).
Disable variable refresh rate of your monitor (FreeSync, G-Sync)
  1. Set fixed refresh rate for Undertale in control panel of your graphics card or disable variable refresh rate completely.

Game Doesn't Start On Linux

Game window flashes briefly before closing or doesn't appear to start at all
Use Wine/Proton instead of the native Linux version.
The native Linux release of the game does not always open due to missing packages on your system or due to Linux trying to run it in 64-bit mode instead of 32-bit mode. If these two issues are resolved, you can run the game natively. However, it is generally easier to use Proton or Wine to play the game instead.
  1. In Steam, open the Properties tab of Undertale. Then, enable the "Force the use of a specific Steam Play compatability tool" setting and select the latest release of Proton from the dropdown menu. This will download the Windows version of the game and open it via Proton.
  2. For other platforms, download the Windows version of the game and the latest stable release of Wine for your distribution. Then, run the executable with Wine.
Install required packages manually

If you would prefer to run the native Linux release of the game, you can install the necessary packages manually.

Arch Linux: The package requirements are: lib32-libpulse lib32-alsa-lib lib32-openal lib32-glu lib32-openssl-1.0[4]
Other distributions may not be able to install all of the required packages due to missing package availability, such as openssl-1.0.
