    After seeing the nVidia web driver release for El Capitan today, I installed the 10.11 Public Beta on my Mac Pro. I ran nv_disable=1 before starting the install, then via screen sharing I went back in, did sudo nvram boot-args="nvdrv_drv=1 rootless=0"

    I installed the El Cap web driver, made sure nVidia web driver is selected, but the system will never come up on the monitor. The only way I can get in at all is via screen sharing on my Macbook Pro. Is there some other boot args I need to use or any reason why I can't get anything from the display?

    If you are installing an unsigned driver, you will also need "kext-dev-mode=1"

    As a result, the line would be:
    sudo nvram boot-args="kext-dev-mode=1 nvdrv_drv=1 rootless=0"
