Looks like this display.
You can simply follow the instructions outlined in post #10. Only the curl commands in step 2 would need some adaption:
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
And of course the content of “/boot/userconfig.txt” has to be adapted to the different overlay:
cat >> /boot/userconfig.txt <<EOL
dtparam=spi=on
dtoverlay=tft35a
EOL
