Here’s the output

# This is a minimal sample config file, which can be copied to

Run
sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-fbturbo.conf -o /usr/share/X11/xorg.conf.d/99-fbturbo.conf
again as the previously downloaded file has probably been overwritten by installing “xserver-xorg-video-fbturbo”…
Then disable and re-enable the Touch Display plugin.

Holly smokes, it worked. The touch is borked tho. Looks mirrored vertically and somehow the scaling is off.

Is the display currently working in landscape mode?
Yes it is. Power connector coming from bottom left ant top is where the GPIO is.

It’s just a guess, but maybe saves time: Try the calibration file for a rotation by 90 deg.
sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-mhs35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf
If this should not help revert to the previous file
sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-mhs35-0 -o /etc/X11/xorg.conf.d/99-calibration.conf
Then enable the mouse pointer on the Touch Display’s config page to be able to easier follow where touch events happen when you touch the screen at certain locations or drag the pointer from right to left and from top to bottom. Describe the results in detail or maybe upload a video.
Up is LEFT, Down is RIGHT, Right is UP, Left is DOWN. Yup -90 worked like magic.

Yes, that is exactly the case! It’s small, but now I can change the song near the soundbar.

Great!
For future readers I have edited the command to download the proper calibration file accordingly.

Hi, for 2.9 version it works fine, but after update to 3.x (because of Spotify plugin), I’m not able to get my 3,5’’ display working. Anybody already fixed it for the newest version please?

Assuming you are on a fresh Volumio system:
Install the Touch Display plugin.
Connect to Volumio via SSH .
Execute
sudo apt-get -y install xserver-xorg-video-fbturbo
sudo apt-get -y install xserver-xorg-input-evdev
sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
