I have been trying to simply rotate the screen on my Raspberry Pi so it looks like portrait mode. I can't seem to figure out the problem. I go to
sudo nano /boot/config.txt
And then I added both the lines
lcd_rotate = 2 display_rotate = 3
I have looked on all the forums and some say to use the first one and some say to use the second one. I have tried all different values and combinations to no avail. Please send help. Any help is more than appreciated.
