Edit: I’m glad so many of you have had no issues with multiple monitors. My set up is a little unusual (3rd display is an infrequently used large tv hooked through the receiver) and is definitely solveable but will take some effort (and honestly, I’d rather spend my spare time outside or with friends, so who knows when I’ll fix it.)
So have money.
I have two extra monitors, one of them is technically a small low res LCD TV, another is in an elderly monitor that I can only turn on and off by plugging and unplugging it because its power button work’s 1 out of 1000 times its pressed. They work, why spend money to replace them, they are just used to monitor temps, music players, and Discord.
Also this flies in the face of sustainability. I’d figure sustainability is also a major motivating factor of Linux, given its association with other progressive tech movements like right to repair. If I have some random jank old hardware, it’d be nice to not have to just throw it away for the sake of switching to Linux. In fact, Linux does save some hardware of course and gives them new life sometimes. I’ve revived some old laptops before with it.
I say this as a Linux advocate, I use Windows due to current necessity. I also use Linux (Not just on a Steam Deck, but yes on a Steam Deck). I’d stop using Windows entirely but I’d need to be richer or accept significant downgrades. I’m not the former and I wont do the latter.
I get what you are saying but sometimes new is needed. For example at work they wanted me to have new not used… For some reason. (They paid anyway)
