Help and Support Guides

Since I don’t know in what state your Volumio installation is now, I recommend to start with a fresh Volumio system, i.e. start from scratch.

  1. Install the Touch Display plugin.

  2. 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

    sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/mhs35-overlay.dtb -o /boot/overlays/mhs35.dtbo

    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

    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

    cat >> /boot/userconfig.txt <<EOL

dtparam=spi=on
dtoverlay=mhs35
EOL

  3. Reboot.

Edit: Step 2 contains commands which are not correct for the display shown in Rue’s previous post. However, I’ll leave them here anyway so that the following communication with Rue remains comprehensible.

The correct commands for the display in question are:

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

sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/tft35a-overlay.dtb -o /boot/overlays/tft35a.dtbo

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf

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

cat >> /boot/userconfig.txt <<EOL
