 #### Touchscreen touch rotation
 If your touchscreen isn't registering touches properly after the screen has been rotated, you will need to apply a
-transformation matrix. You can have the matrix be one of the following:
+transformation matrix.
+
+First you will need your device name.
+
+Run: `DISPLAY=:0 xinput`
+
+Output
+```
+⎡ Virtual core pointer                          id=2    [master pointer  (3)]
+⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
+⎜   ↳ ADS7846 Touchscreen                       id=6    [slave  pointer  (2)]
+⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
+    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
+```
+In this case the device is the ADS7846 Touchscreen, yours may be different
+
+You can test a change by running:
+
+`DISPLAY=:0 xinput set-prop "<device name>" 'Coordinate Transformation Matrix' <matrix>`
+
+Where the matrix can be one of the following options:
 
 * 0°: `1 0 0 0 1 0 0 0 1`
 * 90° Clockwise: `0 -1 1 1 0 0 0 0 1`
 * 90° Counter-Clockwise: `0 1 0 -1 0 1 0 0 1`
-* 180°: `-1 0 1 0 -1 1 0 0 1`
+* 180° (Inverts X and Y): `-1 0 1 0 -1 1 0 0 1`
+* invert Y: `-1 0 1 1 1 0 0 0 1`
+* invert X: `-1 0 1 0 1 0 0 0 1`
 
-To check the current matrix, you will need your `<screen name>`
-(which can be found via the last section, ex: "wch.cn USB2IIC_CTP_CONTROL").
-Run the following command: `xinput list-props "wch.cn USB2IIC_CTP_CONTROL"`
-
-It will output something such as:
-```
-Device '<screen name>':
-        Device Enabled (115):   1
-        Coordinate Transformation Matrix (116): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
-        libinput Calibration Matrix (247):      -1.000000, 0.000000, 1.000000, 0.000000, -1.000000, 1.000000, 0.000000, 0.000000, 1.000000
-        libinput Calibration Matrix Default (248):      -1.000000, 0.000000, 1.000000, 0.000000, -1.000000, 1.000000, 0.000000, 0.000000, 1.000000
-        libinput Send Events Modes Available (249):     1, 0
-        libinput Send Events Mode Enabled (250):        0, 0
-        libinput Send Events Mode Enabled Default (251):        0, 0
-        Device Node (252):      "/dev/input/event0"
-        Device Product ID (253):        6790, 58083
-```
-
-You can verify by checking that the 'Coordinate Transformation Matrix' or 'libinput Calibration Matrix'.
-
-You can test a change by running: `xinput set-prop "<screen name>" 'Coordinate Transformation Matrix' <matrix>`
-
-Replace matrix with one of the options above, such as: `1 0 0 0 1 0 0 0 1`
+For example:
+`DISPLAY=:0 xinput set-prop "ADS7846 Touchscreen" 'Coordinate Transformation Matrix' -1 0 1 0 -1 1 0 0 1`
 
 To make this permanent, modify the file `/etc/udev/rules.d/51-touchscreen.rules` and add following line:
 
 ```
-ACTION=="add", ATTRS{name}=="<screen name>", ENV{LIBINPUT_CALIBRATION_MATRIX}="<matrix>"
+ACTION=="add", ATTRS{name}=="<device name>", ENV{LIBINPUT_CALIBRATION_MATRIX}="<matrix>"
 ```
