This is mostly just how I setup some things. It's just to be used as a “check list” or “recommendations”.
PRO-TIP: You can dim your screen lower than your hotkeys allow you on most laptops! Hit Super once, type bri and hit Enter (= opens “Brightness & Lock”). And adjust it in there, be careful not to turn off your backlit completely! As I've noticed on my ThinkPad T450s I can't adjust it if is on the lock screen.
Before first login (but at login screen after installation - fixes a rare bug, that I always encounter..better be safe than sorry):
Not sure where the problem rely, but if you want wireless-ac speeds. You need to not have your SSID available on the 2.4GHz band.
Ubuntu loves to scan & connect on the 2.4GHz band, before the 5GHz band. Even though you marked 5GHz to be prefered! Might just be my Intel 7265 that are the problem ;) But worth knowing in case you get speed problems.
If it's a laptop, you should install TLP
sudo add-apt-repository ppa:linrunner/tlp sudo apt-get update sudo apt-get install tlp tlp-rdw
If it's a REAL ThinkPad, you might want to consider installing these aswell: tp-smapi-dkms acpi-call-dkms
If you get scrambled text sometimes upon return from sleep (Lenovo Thinkpad T450s is mostly affected by this). Boot with these kernel options:
acpi_sleep=s3_bios,s3_mode
Preferred software:
sudo apt-get install powertop screen irssi clementine gpicview mpv
