Install the Locus Lock GUI
The Locus Lock GUI provides the primary workflow for configuring, verifying, and operating PpRx. GUI-based setup is recommended before moving to CLI-only workflows.

bash -c "$(curl -fsSL https://install.locuslock.com/gui_installer.sh)"
The Locus Lock GUI is included in all variants of LEO100.
For installations on NVIDIA Jetson computers, disabling VSYNC for Qt applications improves GUI performance. Run the following command in a terminal:
echo "QSG_NO_VSYNC=1" | sudo tee -a /etc/environment
Reboot the Jetson for this setting to take effect.
