I'm sure somebody here is doing this and I'd like details.
I have an old 64 bit HP Pavilion DM4 laptop with HDMI. It works OK as TV entertainment center with Ubuntu 20.04 except for webcam(?). However, I think Puppy would be faster, and, besides, I like PUPPYS!
I tried installing 64 bit Bionic Puppy, but the windows didn't match the 55" TV screen size and couldn't be corrected with tools provided. I also couldn't get HDMI sound working. It appears this is a common problem, but a search on HDMI here didn't find any solutions.
