I've only ever just straight up downloaded the source and installed it myself, never had any issues with Ruby updates...
You check it by putting chrome://gpu in the address bar.
Why can no laptop manufacturer even make this an option?
Are you telling me that for some reason it's not using any hardware acceleration available while watching YouTube? How do I fix it?
It's a design choice.
Also, different Linux distros/DEs prioritize different things. Generally they prioritize performance over battery life.
That being said, I find Debian GNOME to be the best on battery life. I get 6 hours on an MSI laptop that has an 11th gen Intel processor and a battery with only 70% capacity left. It also stays cool most of the time (except gaming while being plugged in) but it does have a fan...
Off the top of my head there's a Debian based one, a Fedora based one, webOS, PostmarketOS, probably others. Wouldn't be that difficult but yeah, the cost of entry is still probably tens of millions.
