I have purchased a 5 in touchscreen and the display feature is working great but I have issues trying to get the touch aspect to work.
Here is a link for the one I purchased: https://www.amazon.com/gp/product/B07NRYPZM1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
I am currently using a rock pi x B 4gb 32 emmc with a fresh version of ubuntu mate 18.04 installed. I have the screen plugged in via hdmi and attached at the GPIO pins. I am still unable to detect the touch screen even after working through the walkthrough at http://www.lcdwiki.com/5inch_HDMI_Display
I cannot run the xinput-calibration and if I try to calibrate from ubuntu settings it says that there is an error and does not detect any calibratable devices.
I did notice when I needed to install the drivers under the arm architecture what are the amd64 options for drivers and is this device compatible with the rock pi x B.
Thank you for any help you can provide!
