Linux USB multiseat audio support

Here’s how to add audio support on top of the previous instructions for getting USB multiseat running on Linux, with a Plugable UD-160-A type device.

Setting up USB multiseat with DisplayLink on Linux (GDM up to 2.20)

Soon, we’ll be able to plug inexpensive zero-state USB docks/terminals into new Linux systems, and a new graphical login will pop up in a completely plug and play fashion. Many users can then simultaneously share any single Linux PC. This is great for education, libraries, internet cafes, etc — anywhere where you have clusters of […]
