I’ve got the legion y540 with an RTX 2060, apparently they made this same model number with a couple different gpu‘s.
I have no idea if it officially has linux support or not, I just got frustrated when it wouldn’t stop bluescreen’ing with windows 10. Ubuntu worked fine but was finnacky with peripherals, and I couldn’t change the brightness without fixes. Pop!OS has just worked perfectly across the board, straight out of the box.
What’s whacky is I could swear games run better on linux. Not even natively, like WINDOWS games run better through proton than they did when the same system ran windows. I’d bet a lot of it is just overhead from general bloat; windows is expensive to run these days.
If my experience is anything to go by, just start installing whatever OS strikes your fancy and hope for the best. Keep a windows usb handy just in case, but just start fucken around! You could spend a week reading documentation on ONE SINGLE OS, or you could spend just an afternoon trying probably every single OS you could find a modern ISO for. Just make sure you try the popular ones first hahaha
