1 year ago This is https://github.com/MirServer/mir/issues/2678 - due to a quirk of the current Mir implementation we (unnecessarily) require that each output be associated with a GL interface that can render to it.
This limitation is in the current batch of work, but we do not yet have an ETA for when the fix will land.

I cannot get it to work with a DisplayLink display, It worked fine with an HDMI monitor on the same computer, I tried with ubuntu core, server and desktop and same results.
You can find below the logs if that helps or if I'm missing something.
Thanks in advance.
