llamafilm Posted July 19, 2016 Share Posted July 19, 2016 I want to understand what exactly this command is doing. My understanding is that nvda_drv=1 tells the OS to use Nvidia web driver, which does the same thing as switching it in Nvidia pref pane. Right? But what does nv_disable=1 do? I don't think it's the exact opposite. When I first installed OS X, before I installed Nvidia web driver, this argument had some effect. If it disables OS X built-in GPU driver, then what driver is being used instead? Must be something, because I'm still able to boot to a GUI, albeit slow, in this case.

al6042 Posted July 19, 2016 Share Posted July 19, 2016 With the option "nv_disable=1" the gpu is only used with standard framebuffer functions (no QE/CI oder 3D-Stuff). This is one of the options do get a not supported Nvidia GPU running while installing OSX... Link to comment Share on other sites More sharing options...
llamafilm Posted July 19, 2016 Author Share Posted July 19, 2016 I see. So with nvda_drv=0 and nv_disable=1, the OS X built-in Nvidia driver is being used, but with some features disabled? Link to comment Share on other sites More sharing options...
al6042 Posted July 20, 2016 Share Posted July 20, 2016 Only the framebuffer part of the nvidia drivers will be used. That's why there will be no QE/CI Link to comment Share on other sites More sharing options...
DuongTHVN Posted July 21, 2016 Share Posted July 21, 2016 nv_disable = 1 same as no nVidia kext to load ( for all default apple nvidia kext and webdriver ). Link to comment Share on other sites More sharing options...
Pavo Posted July 21, 2016 Share Posted July 21, 2016 You would never use nvda_drv=0, just wouldn't do anything honestly, same as not using nvda_drv=1 at all Link to comment Share on other sites More sharing options...
