GPU can provide a performance boost to some operations such as web browsing, but can increase power consumption significantly. For this reason, I would like to deactivate it temporarily while the laptop is not connected to an external power supplier.

  • How can I make Linux deactivate the discrete GPU while running on battery?
  • Is there an automatic way to do it?
  • Is there a manual way to activate/deactivate the GPU using a single command line?
