I don't like Ubuntu that much but one thing they really do right is a tool that made installing the few drivers not built into the kernel stupid easy. That's the number one thing I see people mess up with Nvidia drivers. You always install Nvidia drivers through your distro app store/package manager never the website.
I understand the mistake but it's painful to see someone manually install Nvidia drivers from their website just for it to shit the bed in a kernel update.
I'm sure the update manager was probably very important back in the day but I am glad updates come through the software manager now. Even though I don't use it it's very intuitive.
