Install LTX Desktop on Linux

Updated July 10, 2026 13:36

LTX Desktop runs on Ubuntu 22.04 and similar Linux distributions with a supported NVIDIA GPU. On machines with a qualifying GPU, generation runs locally. On other hardware, it uses LTX API mode.

Before you start

Make sure your machine meets the requirements for local generation:

Ubuntu 22.04+ or similar distribution (x64 or arm64)
NVIDIA GPU (32GB+ VRAM recommended)
NVIDIA drivers installed
160GB+ free disk space
Internet connection for initial model download

If your machine doesn't have a qualifying NVIDIA GPU, LTX Desktop will run in API mode instead. See Local mode and API mode in LTX Desktop for more.

How to install

Go to the GitHub releases page and download the file for your architecture:
- x86_64 (most machines): LTX-Desktop-x86_64.AppImage or LTX-Desktop-amd64.deb
- ARM64: LTX-Desktop-arm64.AppImage or LTX-Desktop-arm64.deb

For .AppImage: make it executable, then run it.

chmod +x LTX-Desktop-x86_64.AppImage
./LTX-Desktop-x86_64.AppImage

For .deb: install it with:
```
sudo dpkg -i LTX-Desktop-amd64.deb
```
Then launch LTX Desktop from your applications menu.

What happens on first launch

LTX Desktop will download model weights and required components on first launch. This requires internet access and at least 160GB of free disk space.

Once the download completes, LTX Desktop detects your GPU automatically. If your machine has a supported NVIDIA GPU, local generation will be available. Otherwise, the app runs in API mode and will prompt you for an LTX API key.

To speed up generation and save memory, it's recommended to add a free LTX API key for text encoding even on local-mode machines.

Troubleshooting launch errors

If the app fails to start, check that your NVIDIA drivers are installed and up to date — outdated drivers are the most common cause of launch failures on Linux.
