Tips

Set Display Density

The Raspberry Pi will report the same display density (240dpi) for any screen plugged into it, which may make the UI appear too large or too small.

You can set the display density on the command line using:

$ adb shell
$ wm density <new density>

where is your desired display density. For the official Raspberry Pi 7" touch screen I recommend:

$ wm density 142

Flip Display

How to flip the display on a Raspberry Pi touchscreen (needed for some cases which mount the display upside down).

Plug the SD card into an SD card reader and mount the boot partition (you may need to create the /mnt/sd directory first and replace disk2s1 with correct device reference for your computer):

$ sudo mount -t msdos /dev/disk2s1 /mnt/sd

Edit config.txt:

$ cd /mnt/sd
$ sudo nano config.txt

Add line:

lcd_rotate=2

Unmount the SD card:

$ sudo umount /mnt/sd

Alternatively you can flip the orientation in AndroidManifest.xml, but it will only apply to the Kitfox app:

<activity android:name=".MainActivity" android:screenOrientation="reverseLandscape">
