----------------------------- Delete here & above before posting below -----------------
I am completely new to programming, I know nothing, I trusted a tutorial, but I can’t get the touch of the display connected in HDMI to work, I inserted these lines in the config:
hdmi_group=2
hdmi_mode=87
hdmi_timings=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
display_rotate=1
and the display works, I installed the TouchScreen plugin, I activated it, but it DOESN’T work, to be able to control Volumio I have to use the PC or the Smartphone.
Can you help me, Thanks Andrea
Sorry for my bad English

Modified the correct location for custom settings.
[MOD=Wheaten]

It works for me in /boot/userconfig.txt like this:

initramfs volumio.initrd
#GPU_MEM=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
force_eeprom_read=0
hdmi_group=2
hdmi_mode=87
hdmi_timings=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
hdmi_blanking=1
display_rotate=3

Seems just a waveshare screen.
Identical to mine.
Please replace the content of /boot/userconfig.txt with:

max_usb_current=1
max_framebuffer_height=1280
hdmi_group=2
hdmi_mode=87
hdmi_timings=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3

If you added things to /boot/config.txt remove what you have added.
Reboot and test.

If it still fails, perform a factory reset as I have no clue which tutorial you have used and if that caused things to break.

And make sure you have connected all ports of the screen:

  • HDMI
  • Power
  • Touch

And monitor the log when you installl the touch display plugin, to make sure there are no errors.

If I understand @aavanzi correctly the display already works, but not the touch function.

Editing “/boot/config.txt” is not recommended as modifications will be overwritten on Volumio updates. Instead use “/boot/userconfig.txt” as proposed by @Wheaten.

I’m sorry, do you have the Touch Display plugin installed?

8

Yes, display already works, touch no

9

Yes, plugin installed

Please post the output of

cat /proc/modules

Sorry, I don’t have these folders in my boot dir

You have to connect to Volumio via SSH and execute cat /proc/modules from Volumio’s command line.

Done, but touch doesn’t work, I give up. Thanks for the help

Executing cat /proc/modules was not intended to bring touch to life, but the output would be needed for further investigation. :wink:
