I didn’t know about driverless printing. If it works out I’ll switch my parents over too since the lower maintenance updating is great and printer is the only thing they need that I wasn’t sure about.
The undervolting thing is on an old Intel, I think haswell. A lenovo t440p with the standard fare mod pack. I forgot what it was called but there was some procedure involving mok installation and signing the module that allows voltage control, and/or patch to bypass some aspect of it. I was only reading up on it before I switched distros to bazzite after liking it on steam deck and now it looks like I might have to make a custom ublue image to achieve this if I understand correctly. I’ll probably just switch to seabios and do away with the uefi entirely though as tianocore doesn’t have a bios settings menu but one can be added as a payload when using seabios.
