Wayland without problems it might have something to do with the age

I have an application called Switcheroo running, do you know what that is for ?
Yes, I will give a reference below but first this:
There are at least 2 kinds of hybrid graphics laptops
1) Intel CPU (including Intel discrete graphics chip) & Nvidia GPU
2) Intel CPU (including Intel discrete graphics chip) & AMD GPU
What works for 1) need not work for 2) and vice versa with respect
to configuration and switching.
With respect to 1) the code words were 'optimus', 'switcheroo'
and more recently 'prime'.
With respect to 2) the code word I know is 'dynamic switchable graphics'
and how this works under Linux I have no idea.
Furthermore AMD used to have a closed source driver (I think they
still have, was almost impossible to install under Linux) and the
more recent opensource 'amdgpu' driver that as far as I know
works with all the latest AMD GPU's.
So read up a little on this so you won't be confused by advice
that might only apply to the 1) situation!
A reference for switcheroo is:
but as far as I know this only applies to the 1) situation
Have a look at this url:
