Your
linux system is very responsive on the Pi4, more than the buster arm7 edition that I had before. Chromium seems to be more responsive, as much as the other softwares.
I have a ason usb hub in which my usb mouse and keyboard were plugged, and this usb hub was plugged into the Pi4. Plugging them directly to the Pi4, without the usb hub did the job. The mouse and the keyboard are responsive.
I intended to add a few of the softwares that I like.
sudo apt-get update gave some error messages:

I have a low voltage issue with the Pi4. I might find another
power supply.
I will follow the setup that you propose in the manual tomorrow.
Thanks for the guidance.
