Raspberry Pi

In case you encounter problems when running Great Bear on a Raspberry Pi, check the following sections.

Check operating system version

Make sure that you have installed one of the supported operating systems on your Raspberry. To display the operating system, run:

(cat /etc/*-release |grep DESCR ) ; uname -a ; uname -m

The last line of the output should include aarch64.

Ensure each host has a unique name

Each node in Great Bear must have a unique name. If this isn’t the case then a variety of network related issues may appear.

To change the hostname to a unique name:

sudo nano /etc/hostname

Change the name and save your changes.

Note: Changing the hostname takes effect only after rebooting the Raspberry Pi.

Bad display resolution

xrandr can show incorrect resolution on some RPI4 images due to overscan enabled by default. If your screen resolution seems to be incorrect, add the following line to the /boot/firmware/usercfg.txt file, then reboot the system.

# Disable compensation for displays with overscan

If these steps do not help resolve your issue, then please contact the Great Bear administrator of your organization, or the Great Bear Support Team.
