Linux is super reliable, and unless you use cutting edge distro, it’s pretty rare than anything breaks. Even Fedora is pretty stable from experience
The only true problems I ever had (and still has), were with Nvidia. And switching distros ain’t saving you. Linux mint? Breaks on suspend. Nobara? Memory leak. Trying newer versions to see if it fixes it? Where’s my bootloader…
I do understand that laptop RTX 3070 are not common, but still. I just want it to work, and have cuda on it. Is that too much to ask?
Of course. Mileage may vary. On some systems it may always work, on others it’s “what’s broken this week”.
