From my limited research and understanding, Nvidia makes Linux drivers, but they’re closed source. These work fine. They open sourced some stuff but not enough to really change much yet.
There are also FOSS drivers, but the performance for those vary.
Is this correct? Should I stick to proprietary drivers if I want consistent performance?
I don’t know why you are researching three dead window managers, but it’s generally not something you need to think about. Just like how you don’t need to know about dwm to use MS Windows. But if you have specific questions about WMs I can try to answer them here.
They’re included in Linux Mint with the option to choose between them. I have a problem where when I close my laptop lid and open it back up, the unlocked screen will display for like a solid 2 seconds before switching to the locked login screen. I’ve tried all the different WMs but the only one that doesn’t do that is Compiz, but it has screen tearing so I switched back to Xfwm4
I had assumed that Linux Mint (with Cinnamon) users Mutter, but apparently it uses something called Muffin instead. But if you are seeing these other options then I assume you did not install the Cinnamon version but the XFCE version instead. I guess they don’t package it correctly or something, but XFCE and xfwm should be robust enough to handle closing a laptop lid correctly.
(in other words, i don’t know what the problem is but I think I’d recommend just using the standard implementation -> Mint with Cinnamon)
