I have a feeling you’re talking about the TTY. You can’t use the mouse cause there’s no graphical interface to begin with. You’re in “pure” console mode. It’s probably why fonts look weird too. It’s probably just not running at your monitor’s native resolution.

As other people said though, it’s pretty much expected. Servers are more or less expected to run “headless”. You’d typically SSH in rather than plug a monitor directly in the machine.
