Troubleshooting

Is something in Bevy not working as expected? Maybe one of these will resolve your problem:

Unable to find a GPU #

thread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers!'

This error message means that bevy is unable to draw to your screen. Causes include:

Vulkan-compatible drivers not installed. To fix this, install/update the drivers. On Linux this may be vulkan-intel or vulkan-radeon.
Trying to run an example on a headless machine. To fix this, install a GPU!
