This system uses hybrid graphics (nvidia optimus), but I'm currently
running Intel graphics only. I've seen some solutions around the net
to activate and use the nvidia GPU, but haven't tried any of them yet.
So far, Intel graphics is doing good for what I need, so activating
the nvidia GPU is not a priority right now.
After my first post, I've noticed that all those pointer problems go
away if I disable the system's touchscreen device. Therefore, it seems
that the mouse and the touchscreen are fighting each other. Now I'm
trying to get rid of the problems while keeping a working touchscreen.
