Troubleshooting • Re: GeekPi tower OLED with OS Trixie

Ok, I have tried the venv

I tried these steps.
First, as always, update and upgrade, then

python3 -m venv ~/luma-env

~/luma-env/bin/python -m pip install --upgrade luma.oled

The terminal comes back telling me the dependencies are all successfully installed

cbor2-6.1.3 luma.core-2.5.3 luma.oled-3.15.0 pillow-12.3.0 smbubus2-0.6.1

I then did this to add my account

sudo usermod -a -G spi,gpio,i2c mindfarter

When I hit return, it did not seem to do anything.
The OLED is still dark even after rebooting

What am I missing?

Thank you
