"Just a driver issue", unless it's a temporary regression in the Linux drivers, basically means the hardware manufacturer didn't use standard interfaces or write a good-enough spec for interoperability.

Solutions are calling your manufacturer and filing a support request, or voting with your wallet and picking another manufacturer next time.

Hah, that's a good one. Voting with your wallet never helps when you are a niche within a niche, like a Linux user.

How many hardware manufacturers tell you that their device is supported on linux?

Lenovo, Dell, Intel, Realtek, nvidia, Logitech, Samsung, AMD and many other big brands tell me clearly on their product spec that their hardware supports Linux. It's not like there is a shortage of choice.

Oh, can you tell me then, of a Laptop with Touchscreen, good hardware and Linux support?

I have been looking for one since ages.

Thinkpads and a lot of Dell laptop models both have good hardware and Linux support. I cannot recommend a laptop with a touchscreen, as I have never used nor needed one.

Dell XPS 15 or 17?

I had a Matebook X Pro and it worked really well with Ubuntu but the battery life was terrible in Linux. Maybe it's something that's been fixed or can be tweaked.

Battery life on linux laptops can be indeed improved by tweaking, I did so on various devices. But I never came close to windows battery life and I allmost bricked a brand new laptop while doing so (only save was to tear it apart). So beware of what you are doing.

Thinkpad X1 Carbon, although I'm not sure what the touchscreen support actually looks like (I bought the Windows version of the machine and installed my own Linux distro)

Either you can install good proprietary drivers from the manufacturer, or they don't exist and you have to make do with the open source ones.
