One fun thing you can do with the display is have it as your main console instead of the HDMI/TV output. Even though it is small, with a good font you can get 20 x 40 of text. For more details, check out https://github.com/notro/fbtft/wiki/Boot-console
First up, we'll update the boot configuration file to use the TFT framebuffer /dev/fb1 instead of the HDMI/TV framebuffer /dev/fb0
sudo nano /boot/cmdline.txt
you can also edit it by putting the SD card into a computer and opening the same file.
At the end of the line, find the text that says
rootwait and right after that, enter in:
fbcon=map:10 fbcon=font:VGA8x8 then save the file.
On the next boot, it will bring up the console.
Note that the kernel has to load up the display driver module before it can display anything on it so you won't get the rainbow screen, a NooBs prompt, or a big chunk of the kernel details since the module is loaded fairly late in the boot process.

Add the following line to /etc/rc.local
sudo sh -c "TERM=linux setterm -blank 0 >/dev/tty0"
on the line before the final
You can disable this by editing /etc/kbd/config and looking for
