Touch does not work on official RPi display

[ValDog]

I've done all the recommended things (update, upgrade, rpi-update) and checked that the small cable is firmly seated, but can't seem to get the screen to respond to touches. Anyone else seeing this issue?

same here.
The first time i started the gui with "startx" the touch screen did work.

Now it is no longer possible to get the touch functionality to work again. Tried all the hints in this forum with no result.

Any ideas? Is it possible to check if there are some kind of driver errors?

Once updating with rpi-update ( which I believe is now unnecessary since apt-get update && apt-get upgrade will now install the fix ) I haven't seen any further problems with the touchscreen across multiple displays.

This is worth a try, to bring you back into the world of sanity rather than pre-release;

Code: Select all

sudo apt-get install --reinstall raspberrypi-bootloader
sudo reboot

Let me know if it helps.

It helped. Big thanks.

Appreciate the feedback, but still not solved for me...

1) If you do lsmod is rpi-ft5406 listed?
2) Install evtest (sudo apt-get install evtest) then run it... Touch the screen do you get anything out of the driver?

rpi-ft5406 is listed when I run lsmod.

Running evtest I get no response when I touch the screen.

Sounds like a faulty touchscreen...
