Does the display work if the rpi4 run Ubuntu server?

[MorganLindqvist]

Hi,

My rpi4 is running Ubuntu 22.04. Is it possible to install this code on Ubuntu so I can get out the information and display it?

My rack is ordered but have not arrived yet so I can not test.

Hello Morgan,

I got the display to work on Ubuntu 20.04, the instruction is a bit different based on Ubuntu's unique way of doing things.

First, you would need to enable i2c and baud rate by editing this file /boot/firmware/usercfg.txt append below

dtoverlay=gpio-shutdown
dtoverlay=gpio_pin=4
dtoverlay=active_low=1
dtoverlay=gpio_pull=up
dtparam=i2c_arm=on
dtparam=i2c_arm_baudrate=400000

next, you would need to install i2c packages which does not come by default with the ubuntu server

sudo apt install -y python3-pip python3-dev python3-pil python3-setuptools python3-rpi.gpio i2c-tools]

Lastly, you need to add your user to the i2c group, in my case the user is the default ubuntu user

sudo usermod -aG i2c ubuntu

You can then follow the rest of the instructions by compiling the display driver.
