Sleep usually works, assuming you get a laptop that's known to with with Linux. The arch wiki is good for this. HiDPI is hit and miss. Some applications work, some (especially Java) break badly. Expect to need manual, fragile configuration. You also cannot set scaling per-screen, so you're SOL if you have heterogenous monitors. Personally I use Windows. I check back in Linux every few months, but WSL seems to be improving far faster than native Linux is, so there's not much reason to use it anymore. Even once HiDPI works, assuming that happens, by that point I'll have HDR and VRR as requirements... and I have no confidence that those will work anytime soon.
