# OpenRR GUI
## Troubleshooting
- Q. Fails to compile.
A. Try to install dependencies mentioned in root [README.md](../README.md).
- Q. Fails to launch GUI.
A. There are several possibilities:
- If the error is command-line arguments or IO related, it's likely that the argument is wrong.
- If you get the error that "GraphicsAdapterNotFound", try passing the "--features iced/glow" argument to `cargo build` or `cargo run`.
- If that doesn't fix the problem, try passing the `LIBGL_ALWAYS_SOFTWARE=1` environment variable.
- On VM (e.g., VirtualBox), you may need to disable hardware acceleration.
