If they’re running Linux, they can’t even do those things.
If they can't login or the screen breaks they run to geek squad. Under no condition will they claim manufacture warranty on an internal part without a techie recommending this and removing the card/part for them
But the reason I'm on windows in the first place is that I left Linux several years ago when I bought a second monitor and Linux would sometimes work great but sometimes fail to display anything on either of them at startup. That just was not useable. I tried again about a year after and same issue - I would like to go back to Linux but I don't have time to roll the dice on being able to start work in the morning or have to ssh in from another device to figure out what happened to my display.
no, on other OSes you just cannot fix it. e.g. for instance on my computer I have a win32 install and for some reason on it the ethernet network speed seems locked to 100mbit-ish while on linux I get my gigabit ethernet performance. what can I do to debug this on windows when i tried the usual install / remove drivers, etc etc ? absolutely nothing, I just learn to live with the issue like most people on that OS.
