I've been using Linux with various GPUs (AMD, nvidia, and integrated) and various distros since 2008 and I've never had this issue.

I worked in a place that built and maintained computers with Linux installed and again never seen the issue you describe.

The hardest time I ever had whit a GPU was back when I was using Ubuntu on an AMD card back in 2008. And the hardest thing then was figuring out what repo to use as newb.

Builds with an integrated GPU in the CPU with a different dedicated GPU used to be difficult until bumblebee came about and now they couldn't be easier.

It is true that people might have to read error messages every now and then, but in the open source community, error message make sense and you can research them entirely yourself.

I don't doubt that you are having an issues, it may be something as simple as your hardware is too new for the distro release you have installed and you should update. However, to say that everyone will have some weird issue is wrong.

I've convinced about 5 friends and neighbors (one over 70) to switch to Linux in the past 2 years. All I did was provide install media and help them boot to it. They figured the rest out and didn't have issues either.
