NitroPad External Monitor

Hey,

installed QubesOs 4.2.2 on NitroPad. There is an Apple Display connected over the thunderbolt port.
NitroPad charges over the port, but the Display is only sometimes (!) recognized. Got it 2 times working out of maybe 20 boots.
I believe, the times when Qubes sees it, I reconnected the display at some point during the boot process.
But this is hard to replicate, maybe it was just coincidental.

Don’t know if this issue is NitroPad or Qubes specific.

Any hints?
