You must install the recommended drivers for your NVIDIA video card, otherwise Harmony will not function.
In general, you should use the latest drivers. New drivers tend to resolve past driver issues. If you already have NVIDIA drivers installed, find the version number by typing:
cat /var/log/Xorg.0.log | grep "X Driver"
- Download the Linux driver from the NVIDIA website:
- As a root user, switch to text mode when installing video card drivers.
- Install the NVIDIA kernel driver.
- Once the NVIDIA driver installation is successful, revert to graphical mode by starting X.
