They really need to update Mint though. Sure it is good… on old computers. Anything made the last couple of years will have issues due to an ancient kernel and mesa. We should stop calling it stable/lts and unstable, because users will always pick the one called stable, even if the ‘unstable’ one is the one that would in most cases work the best for desktop linux. Or at least we should separate the kernel and mesa away from the rest of the ‘stable’ packages, and include recent versions of that by default, to not scare away people with driver issues.
I don’t know specifically about the T470, but if you have an nvidia GPU, you might have issues depending on how the display outputs are connected to the GPUs. I had a T420s at some point with an nvidia GPU, and it was a PITA to get the display output to work on linux. I had to permanently enable the nvidia GPU for that to work (cutting battery life in half), because the display output was connected only to the nvidia GPU. I swore to never buy an nvidia product ever again after that experience.
