LG and Linux

[MR ZenWiz]

I just recently bought a shiny and very tempting new laptop at Costco
- it's an LG-17Z90N-R - 17" screen, 2560x1600 resolution, 10th gen i7,
16GB RAM, 500G SSD, and so on.

Has anyone had any bad experiences with running Linux on an LG?

I want to shrink the Windows partition and put Xubuntu on the thing so
I can make good use of it.

LG seems to think that they can bar me from doing this as it "might
void the warranty."  I don't see how, but I'm wondering if anyone else
has relevant experience.

Many thanks!

Mark
