I want to use this 3.5" adafruit touchscreen, so I followed this tutorial
I ran the following commands from the link :
curl -SLs https://apt.adafruit.com/add | sudo bash sudo apt-get install raspberrypi-bootloader sudo apt-get install adafruit-pitft-helper sudo adafruit-pitft-helper -t 28r
When rebooting I get just a part of the touchscreen that is displaying Raspbian and I want it fullscreen.
I don't know firstly that I need a tutorial for 3.5 inch and not 2.8 inch so what I did I ran this command again with a little change because I'm using 3.5 inch:
sudo adafruit-pitft-helper -t 35r
Another change that I made is to remove the adafruit duplicate in
/boot/config.txt, and now after rebooting the only thing I get is a big white screen.
Update: this what I removed

I got 2 section like described with just the difference in one line
So I removed the first section !!!
I have ran all commands again either for 2.8, or 3.5 but that hasn't changed anything.
Any suggestions will be appreciated :) thanks
adafruit-pitft-helper, and then use the command
sudo adafruit-pitft-helper -t 35rand it might set it up as needed (though the thing seems to be for 2.4" & 2.8")- you could use this tutorial (which is for this), but I would suggest contacting them in case the wrong software/firmware/drivers/stuff blows things up.
