Take the tour ×  When I enabled my Nvidia graphics card, it
changed the resolution of my screen to larger than my screen. As
the result I cannot access any functions that were previously on
the right side of my screen. How do I undo this? I originally

labelled 'NVIDIA X server settings.  Nvidia settings should get
installed when you install one
