While most of Linux versions support plug-and-play functionality for USB external touch monitor, manually installation is still required for vertical touch operation and touch calibration. Due to the increasing popularity of Linux application, we hereinafter show you how to set up vertical display, vertical touch screen settings, and install the touch calibration software in Manjaro Linux.
A. How to Rotate Monitor Display in Manjaro
Display application is already included in xfce Desktop of Manjaro Linux, allowing you to set up the display resolution and direction.
① Enable Display Aplication
Click

Click 《 Display 》
② Set up Rotation
Click Rotation menu：choose Right or Left to rotate the display 90° or 270°→click 《Apply》
Click 《Keep this configuration》for confirmation

B. How to Set Up Touch Screen Rotation
After the display became portrait mode, you may find that the touch response position is different from the actual finger touch location. This is because the initial position of touch panel is still set to landscape. You shall set the initial TransformationMatrix value of touch screen to vertical.
① Find 40-libinput file
In Terminal, key in
cd /usr/share/X11/xorg.conf.d
Key in ls to list all the files in the folder
② Edit 40-libinput file

90° = Option "TransformationMatrix" "0 1 0 -1 0 1 0 0 1"
180° = Option "TransformationMatrix" "-1 0 1 0 -1 1 0 0 1"
270° = Option "TransformationMatrix" "0 -1 1 1 0 0 0 0 1"
Remark: The XY position of different touch screen's start point may be various, so the transformation matrix values of 90° and 270° may be the opposite. For models other than M505T, please try to adjust it yourself!
