The hpallinone is a disaster. This is win computer with everything in the monitor. In order to get it to work hip did some amazing work, with 3 drivers for audio, and a bizarre wifi setup. Come the next win update, and no sound!
Cleaning up the audio drivers didn't work. And then, in desperation, I used the Debian Buster installer with all non-free firmware. It didn't even see the wifi. Then I remembered how Debian is having trouble with wifi lately. So, really no hope.
The realtek wifi relies on closed binary blobs. I think all the drivers in the hp are the same, so don't get this thing. The old guy will just have to take it back. :(
ps. apparently when using non-free blobs you have to turn off secure boot. I'm going to try a live disk first to see if it can figure out all the drivers.
