Ubuntu 18.10 on Thinkapd X1 Yoga Gen 2

Commands

* Brightness keys don't work. Instead
rui@chaiX1YG2:~$ xrandr --output eDP-1 --brightness 0.8


As a temp solutions, I created keyboard shortcuts for 0.8 (super-f6) and 0.3 (supers-f5) settings, using
gnome-terminal -e "sh \home\rui\brightdown.sh" (may require chmod +x)
Via the settings GUI -> add a custom shortcut

* Suspend doesn't seem to work
systemctl suspend -i

* Wayland works, but then cannot change brightness as above (no display named eDP-1)

* There is no option for scaling other than 100% or 200%. 
Workaround - scale text in GUI (does not apply to text inside applications, e,g, Firefx)
rui@chaiX1YG2:~$ gsettings set org.gnome.desktop.interface text-scaling-factor 1.5


## Works well

middle click key, sound buttons, wireless, auto-rotate when laptop tipped, 

## Todo

Check out battery life (just browsing, half brightness) and during suspend

## Debug 

There appear to be occasional issues switching window focus in firefox. And text in the location bar can appear on other half of screen.
