Original GitHub issue: https://github.com/debauchee/barrier/issues/1227

Not really an issue/bug, but it would be really great to support Qubes OS.

I successfully installed and connected the client in a qube, but inputs do not get passed on correctly. (I also tried the sys-usb qube)
Qubes has some good documentation on the handling of USB devices, incl. external mice and keyboards, but I didn't find anthing on non-USB input devices.
Similarily I could not really figure out how Barrier passes the events on to the OS. I tried reading the source code but didn't get beyond the understanding that some form of IPC is used.

Maybe this is an documentation issue, maybe I am not knowledgeable enough about linux, maybe this should never work in the first place.
Either way I would really appreciate any hints/ideas/insights concerning this.

@Tie-fighter commented on GitHub (Jul 28, 2021):

From my understanding Barrier uses PS/2 (interrupts) which do not get passed on to dom0.

A way to solve this issue would be to emulate usb devices which could be handled just like external peripherals in qubes.
Such a solution might prove useful in other usecases too.

Unfortunately implementing such a solution is beyond my current skill level.
