Whew. If you've never done it b4, Arch install is not quite trivial,
unless you know all the package names you need etc. I got it up and
running with a kernel 5.9.10 to command line - and the same *@#*&$§*
black screen. No more time now to go into diagnostics, there are many
more issues I have to solve before I consider this Arch install really
functional. For example lightdm doesn't start, networking doesn't load
either even though I installed the packages... will keep me busy -.-

If anybody has any other ideas on what I could try - I'd be glad to
hear them. Ty, tc
