Setting up Pi Raspian on 7" Pi screen

The Pi screen can be used in any orientation.  I bought a backshell which mounts it in a nice case upside down, however, requiring a 180 degree rotation to work correctly.

do the following:

edit /boot/config.txt

add line:

display_rotate=2

value 1=90
value 2=180
value 3=270

The default keyboard in Raspian is British english.  To reconfigure do the following:

in a bash screen:
rerun the configuration for the keyboard package with dpkg-reconfigure
sudo dpkg-reconfigure keyboard-configuration

reload the configuration with:
invoke-rc.d keyboard-setup start
