What makes Optimus a mess is, that you do not know what outputs are connected to which GPU, or if there is a hardware switch (a mux) in between. The mux would be controlled in software.
The mux, if it exists, can used to select which GPU drives the internal panel. Or, which GPU drives the external monitor. Or, both.
The mux, if it exists, can be used to select which GPU drives the internal panel. Or, which GPU drives the external monitor. Or, both.
Also, it is possible, that a GPU is hardwired to the internal panel, so the other GPU cannot drive the internal panel. The same with the external monitor output, it may be hardwired to one of the GPUs, or there might be a mux. A bad case scenario is, that the Intel GPU is hardwired to the internal panel and the Nvidia GPU hardwired to the external output, and no way to change that. The best case scenario is a mux, which can select which GPU drivers all the outputs.
Basically, you can have ''any'' combination of these possibilities. There is no standard how to wire things. There should be ways to detect the wirings and whether there is a mux and where, but the documentation is not available to the developers.
