I'm not sure which distro would work with your laptop. I would suggest experimenting with live USB images. Maybe using something like Ventoy which enables you to try out multiple live images from one USB stick. But as far as applications go:
- GIMP is native to Linux and should work fine. You might also want to give Krita and Inkscape a whirl. Also, massive props for ditching Adobe. I hate that company as much as it hates their customers.
- Blender works on linux.
- So does Davinci. Allegedly. Haven't used it, but their website says Linux support is available.
- I don't code so, um, no idea. Sorry. Hopefully someone else will weigh in.
- Good news, Linux has working file explorers!
- No ads, at least for the most part. Ubuntu had Amazon's search integrated into their search bar a while back, which caused quite a kerfuffle. Later, they added a toggle to turn this off, but this was years ago. Might want to check just in case.
