I don't use Aida64 Extreme. This is Kubuntu 21.10 only. Version 21.10 has new widgets and touchpads that can be used as widgets, which is not available in the LTS version. I use my 5" display as an internal touchpad. All I had to do was go to the manufacturer's website, download and install the Ubuntu drivers. (Install them before plugging in the display!) It definitely complements my case!I would buy from them again as I have 3 RPI 3b and 2 RPI 4b.
