Touch screen not working on office display


I’ve dismantled it over and over and all the cables are good. Also now using a official power supply and powering over GPIO. It has worked once before but not since the first day i got it.

Help :S


Have you updated Raspbian recently? I’m still confused as to whether the touchscreen fix made it into an actual release, but either way running these in order should get it working:

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update

Don’t get into the habit of running rpi-update, it’s not necessary. It’s not an updater and should probably be named: rpi-install-experimental-pre-release-software-onto-my-pi… although that’s a bit long-winded!
