I bought a Raspberry-pi 400 a while ago to use to learn linux. I also bought this touch screen to go with it GeeekPi-1024x600-Capacitive-Monitor-Raspberry/dp/B075QCXLPF on amazon which works great as a display. However the calibration on the touch is off. It also requires a resolution of 1024x600 or it displays lines all over. I tried to use ts_calibrate to calibrate the display but this just makes the screen show nothing or random lines of random colors sliding all over the place. I tried to contact the maintainer of the tslib but the email on the github page for support blocks emails. Is there another tool that I should be using instead? or is there a way to force ts to use the resolution needed by my display?
Thank you very much.
