Disable the Optimus discrete graphics GPU in Ubuntu using bbswitch | Committed, but not pushed. I’ve recently made the mistake of purchasing the Asus K56VM laptop. I call this purchase a mistake because as well as an excellent spec (3rd gen. i7 processor, excellent screen), this laptop also comes with nvidia’s Optimus graphic card setup. In case you’re not familiar with the Optimus setup, it basically means that your laptop contains 2 graphic cards – 1 that’s built in to the Intel processor, and 1 discrete standalone. Given the proper drivers, and taking into account workload and power consumption, your OS can seamlessly toggle between the 2 cards.
If you use Windows as your OS, everything works nice and dandy; If you use a Linux-based OS, you’re in for a world of pain: Both GPUs are on and active.The HDMI output is “hardwired” to the discrete GPU.The VGA output is “hardwired” to the internal GPU.Only the VGA output works by default.You can work with only one output at a time.You can only toggle between outputs using an external project such as Bumblebee.
