Hi, since upgrading to Volumio 3, I’ve lost the “touch” functionality of my raspberry pi 7" screen (official). Otherwise, the display is fine - it is just no longer touch sensitive. I haven’t used this in the last couple of months, and it doesn’t seem to be a discussed issue, so it might not even be a Volumio 3 issue. Maybe the screen has gone bad? I’m just wondering if anyone has come across this and might have a suggestion to fix it.
I’ve reformatted the SD card a few times, reinstalled Volumio a few times and uninstalled and reinstalled the touchscreen plug-in a few times. Initially after updating to Volumio 3, when enabling the touchscreen plug-in I was met with a black screen (though text appeared on start up and when the plug-in was disabled), but I’ve since got the screen to display properly. It is just the “touch” aspect that is an issue.
I’m a virtuoso subscriber, but I understand that I should still be able to use the plug-ins?
Any suggestions will be appreciated.
I’m using a Raspberry Pi 3B.
I suggest to reseat the DSI cable. If you have a spare one try that, too.
If that does not help, please connect to Volumio via SSH and post the output of
ls -al /dev/input
I will suggest you try and see if the touch connector is loose on the screen pcb.
@Panos70 Yes, that’s worth a look, too.
@DanHillier That is the yellowish cable connected to J4 on the display’s PCB you can see in this picture.
Thanks for the suggestions. I’ve just tried tried re-inserting the cables, with no luck (though, a cable could still be faulty).
The output of ls -al /dev/input is:
drwxr-xr-x 3 root root 120 Feb 22 14:36 .
drwxr-xr-x 16 root root 3740 Feb 22 14:36 …

The content of “/dev/input” shows that an input device has been detected. If you have no other mouse or an IR receiver connected this would probably be the touchscreen.
and touch the screen. When ready press Ctrl+c.
Do you see weird signs in your terminal?
I tried that a few times and it didn’t do anything.
There is no mouse or IR receiver connected.
I’m going to call it quits for tonight. I haven’t tested the touch screen with another program, so I’ll do that tomorrow, and at least that will give me a clue as to whether it is a screen problem or not.
I’ve had two of the official 7" screens lose touch functionality after a couple of years use. I changed the DSI cables and tried them on a different Pi and different power supplies, no luck. Nothing to do with Volumio in my case, same on RPi OS.
Display still wirks fine on both though.
