Ubuntu MATE HiDPI - First Steps

This works almost perfect except after scaling, the touchscreen calibration goes all wonky, along with the stylus.

I’m not on my computer at the moment, but search the package repos for calibrate/calibration or something along those lines. There’s a package that I installed that fixed it for me, even with multiple monitors connected to it.

I figured a workaround tweak.
You just need to set xrandr to 1x1 first before setting it to 0.6x0.6 .

Like this:

 xrandr --output eDP-1 --scale 1x1
 xrandr --output eDP-1 --scale 0.6x0.6

Here is a rotate toggle script I made for my touchscreen device:

#!/bin/sh
rotation=`xrandr -q --verbose|grep eDP-1|cut -b44-51`
if [ $rotation = "normal" ] ;
then
  xrandr -o left
  xrandr --output eDP-1 --scale 1x1
  xrandr --output eDP-1 --scale 0.6x0.6
  xsetwacom set "NTRG0001:01 1B96:1B05 Pen stylus" Rotate ccw
else
  xrandr -o normal
  xrandr --output eDP-1 --scale 1x1
  xrandr --output eDP-1 --scale 0.6x0.6
  xsetwacom set "NTRG0001:01 1B96:1B05 Pen stylus" Rotate 0
fi

Sorry for the delay, I’ve been traveling a lot lately.
Thank you so much for the info. I plan to get started on this install effort this week.
Hopefully, I will be successful.
