    Exclamation Problems with keyboard, WiFi, and screen suspension on Ubuntu 18.04

    Good morning,

    I went through many Debian based distros only not to find any help or support for the issues I encountered, so I decided to go for Ubuntu.

    DISCLAIMER: I feel like this is important. NONE of the issues listed below happened during ANY of the "live-media" trials that come with the installations. Actually, at least issue #2 did not happen even right after the installation had finished, because it didn't require a full reboot, only a restart.

    Issue #1: My distro does not receive my Fn+F12 (WiFi hardware switch) leaving me uncapable of turning the WiFi on. (Also doesn't listen to Fn+F2 and Fn+F3 - which are the brightness dials, but Fn+F6/7/8 work - volume dials)

    Issue #2: I have no way to turn WiFi on. I tried everything software-wise, therefore I believe it's only a matter of getting my keybord Fn combos to work. Here is my info-wireless:
    Code:
