Welcome to the Looking Glass Community Wiki

Looking Glass is a free and open-source application, which allows the use of a KVM (Kernel-based Virtual Machine) configured for VGA PCI Pass-through without any attached physical monitor, keyboard or mouse. This is the final step required to move away from dual booting with other operating systems, for legacy programs that require high-performance graphics.

This wiki is for community additions and supplementary content, which is otherwise not appropriate to include in the Official Documentation. The official docs should always be consulted for primary installation instructions.

If you are looking for help from humans on your problem, please instead see the Looking Glass Category on the Level1Techs forums. You can also join the official Discord for Looking Glass, or join us at #LookingGlass on
