In “/boot/userconfig.txt” try removing
dtoverlay=ads7846
so you only use
dtoverlay=mhs35:rotate=90
Don’t know if it matters, but maybe you also have to move dtoverlay=mhs35:rotate=90 after
dtparam=spi=on.
Good Night @gvolt
Unfortunately it doesn’t work!
to get rid of conscience I took an old screen that had 3.2inch plugged in Raspberry commented the lines
I added
dtoverlay=tft9341:rotate=90
I added
hdmi_cvt=320 240 60 1 0 0 0
I changed 99-calibration.conf para 3.2inch
/etc/X11/xorg.conf.d/99-calibration.conf
Section "InputClass"
Identifier "calibration"
MatchProduct "ADS7846 Touchscreen"
Option "Calibration" "115 3700 3865 155"
Option "SwapAxes" "1"
EndSection
userconfig.txt
##dtoverlay=mhs35:rotate=90

hdmi_group=2

##hdmi_cvt=480 320 60 6 0 0 0
#### Touch Display rotation setting below: do not alter ####
display_lcd_rotate=1
display_hdmi_rotate=1
So I restarted with the old 3.2inch screen that I had kept in a shovel and it worked perfectly so I contacted the supplier of the MHS 3.5inch screen, he will send another one because I have tried everything I can think of! I honestly don’t know what else to do!

Hi, does it work yet? I also have an MHS-3.5 and don’t get the touchscreen to work…
i would say try the settings above…
Some more information required: What is your Pi model and the Volumio version?
Are you on a fresh Volumio system or did you already take some steps to get the MHS-3.5 working? From your post I can only assume that you probably have installed the Touch Display plugin and now the display is showing Volumio’s UI but touch is not working. Please describe in detail what you did to get the display working. If you should have experienced error messages: What did they say?

I tried that off course… It’s just the touchscreen that doesn’t work, screen works
I did these steps and 100 of variations of it.
install the TouchScreen plugin

sudo nano /boot/config.txt => or user config

sudo apt update
sudo apt install lightdm
sudo apt install xserver-xorg-input-evdev
sudo nano /etc/lightdm/lightdm.conf
=>autologin-user=volumio
reboot
best is to wait till @gvolt is here he knows a lot of those settings but some of it is not set yet …
morning gvolt … but light dm is not needed … evdev is not set yet.
Please post the results of
cat /boot/config.txt
cat /boot/userconfig.txt
ls -al /usr/share/X11/xorg.conf.d
ls -al /etc/X11/xorg.conf.d
and
ls -al /dev/input
P.S. What is the purpose of lightdm? It is not needed to have kiosk mode if you use the Touch Display plugin and should not be installed IMHO.
Hi, I didn’t got an error message. I’m using a RPi4 2GB with version volumio-2.882-2021-04-24-pi
The version volumio-2.773-2020-05-05-pi didn’t work with my RPi4 2GB, something about the bootloader.
I also did these steps with an RPi1B+ (I think) and it didn’t work for now.
If someone can tell me which steps they actually took to get it working, would be nice. Only with an MHS3.5inch screen!
Thx

Yes, I didn’t use LightDM at first and you are right, it isn’t necessary, but others got it working with that included… So I tried it. But I will remove it again.

still no improvement
Is the output of

If you run
cat /dev/input/event0
and then touch the screen, do you get any ouptut?
no events what so ever… it doesn’t detect it, so still the driver isn’t working

could you tell me exactly in what order I need to add which rules and if I should try another version of volumio to make it work?
I can do a clean install again if you want
1.install volumio
2. install touchscreen plugin
3. enable ssh
