My laptop has an onboard Intel HD 4000 graphics card and a Nvidia GeForce GT 650M card. When I first installed Ubuntu, it was using the Nouveau open-source drivers by default. Everything seemed to be working fine, but I went ahead and applied the Nvidia (proprietary, tested) driver via "Software & Updates > Additional Drivers". After doing so, I noticed that certain programs didn't window correctly when putting them in fullscreen, as well as the fans working harder and the laptop getting hotter than it used to.
Which driver should I use? Should I get the Nvidia driver directly from their website instead of the Ubuntu "Software & Updates" tool?
Also, does the system switch between using the Intel and Nvidia card depending on power settings?
Sorry for all the questions, I'm still new to Ubuntu/Linux but so far I've been enjoying it :)
Any help is appreciated!
