OK, I will have to go through so me more testing.
In regards to ARCH installation. I am actually also using EndeavourOS 
(EOS) on my side. It's very quick to install and providing quite "pure" 
ARCH Linux experience. Manjaro might be just as good.

I don't want to waste more of your time. Thanks for tracking it down on 
other distros. I will do some more testing on ARCH and potential other 
platforms before coming back here.

Thank you!
