I just recently bought an Eagletec 104-key mechanical keyboard (https://www.amazon.ca/gp/product/B015MPQQ0A/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) and I find that I can't scroll the output in the console in Multi-User mode. When I press Scroll Lock and then PgUp/Dn or the arrow keys it just scrolls through my terminal history. Any other combination of known scroll commands outputs gibberish on the command line. It works fine when I boot into Single-User mode. Any clues as to why this is happening?
