I recently installed Ubuntu 18.10 and I'm having several problems:
Ubuntu does not seem to detect my HDMI and USB C ports
my hotkeys don't work (f1 through f12 behave as f-keys regardless of if my fn key is pressed)
when I shut down, Ubuntu shuts down but my computer stays powered (frozen screed, but still on)
When I put my computer in sleep mode it will not wake up whatever I do
The guy who helped me install it said something about my ACPI maybe not being supported yet (it's a brand new computer).
Can anyone help me solve this? and if it can't be done, can anyone help me reinstall windows properly?
