I am trying to echo an LCD screen attached to my system to confirm the device functions correctly. I am running Ubuntu 18.10.

This is the device as per the contents of /var/log/Xorg.0.log:

[    15.900] (II) This device may have been added with another device file.

I am unsure from the last few lines whether the device is functioning correctly (even though it appears to be from using a stylus on it).

To confirm I have tried:

echo "TESTING TESTING TESTING" > /dev/input/event4

However nothing appears on the LCD when I do so. Am I using the correct method to print something to the screen? Does the log all look ok?

This is part of a larger issue I have of trying to get LCDPROC to render on said LCD.

Thanks
