I am trying to revive an old Lenovo Ideapad Z360 laptop using Ubuntu 20.04 LTS.
On Ubuntu Mate 20.04, I am able to switch from the Nvidia GPU to the Intel GPU just fine. However, on Ubuntu 20.04 (Gnome), switching to the Intel GPU doesn't work!! So my question is: Why does it work on Ubuntu Mate, but not on Ubuntu Gnome?
The problem is described in more detail here: https://askubuntu.com/questions/1232211/nvidia-optimus-on-20-04-switching-to-intel-gpu-works-on-ubuntu-mate-but-not-on
