## Rotating your screen
Press `Ctrl + Alt + F3` to get to a virtual terminal, and use your favorite editor to open `/boot/config.txt` (remember to use `sudo`). Add a line to the end of the file:
- `display_rotate=0` to disable rotation
- `display_rotate=1` to rotate 90° clockwise
- `display_rotate=2` to rotate 180°
- `display_rotate=3` to rotate 90° counter-clockwise
Save the file, and `sudo reboot`.
