i'm new to all this so bear with me. got my pi 3 b+ in the mail today. assembled with no problems with a 7 inch display, and case. booted right up, accepted inputs from the NeeGo input keyboard/touchpad that came with it.
got a fresh 32gb micro sd card and installed kali arm image "kali linux raspberry pi w/tft" and wrote it to the disk. after a slower than normal boot it eventually arrives at the kali login screen. the touchscreen will not accept input, the NeeGo keyboard/pad will not accept input. i rebooted with an extremely basic mouse and keyboard which also did not work. i wrote the raspberry pi image to a USB thumb drive, removed the micro sd card and rebooted with only the USB drive plugged in along with the touchpad/keyboard. it stalled after a few lines, i pressed a few keys on the keypad which registered correctly. i then inserted the kali sd card, booting resumed, ending at the kali login where input is no longer accepted.
like i said, i'm new to all this and dont know where to begin troubleshooting
