Next screen to test

Either 15.6" screen + touch panel + driver or a ready made 17" display that needs to be disassembled.

Or maybe a 15.6", 4k touch screen kit

Last one works fine with a Raspberry Pi 4 + Raspberry Pi OS (64bit + desktop). Need to get the touch panel working. So far:

sudo apt install libts-bin evtest

evtest doesn't show anything else than a keyboard:

root@dltonedraw:~# evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event0:  SIGMACHIP USB Keyboard
/dev/input/event1:  SIGMACHIP USB Keyboard Consumer Control
/dev/input/event2:  SIGMACHIP USB Keyboard System Control
/dev/input/event3:  vc4-hdmi-0
/dev/input/event4:  vc4-hdmi-1
Select the device event number [0-4]: ^C

The flat cable from the panle was connected the wrong way into the controlboard.

So, now I got:

root@dltonedraw:~# evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event0:  SIGMACHIP USB Keyboard
/dev/input/event1:  SIGMACHIP USB Keyboard Consumer Control
/dev/input/event2:  SIGMACHIP USB Keyboard System Control
/dev/input/event3:  vc4-hdmi-0
/dev/input/event4:  vc4-hdmi-1
/dev/input/event5:  ILITEK ILITEK-TP
/dev/input/event6:  ILITEK ILITEK-TP Mouse

Try also xinput to check which input devices available.

Need to understand tslib better (libts... on Raspberry Pi OS)
