Can I use the NVidia driver without Bumblebee on an Optimus chipset?


So it seems that my new laptop has one of these NVidia Optimus hybrid GPUs.

The i915 driver works and gives adequate performance.

If I try to use the nouveau driver, X doesn't start, complaining about No screens found.

If I try to use the NVidia proprietary driver, X doesn't start with the same error as the nouveau driver.

https://docs.slackware.com/howtos:ha...nvidia_optimus

The info at the link above makes me think that while it is possible to use the Intel part of the GPU without Bumblebee, it is not possible to do the same for the NVidia part of the GPU.

Is my understanding correct?

Depends on the bios/firmware. Some optimus laptops you can turn off the Intel and use only the discrete Nvidia. My Lenovo T430 was like that.

AFAIK, the latest (starting from 2014-2015) consumer grade optimus laptops have no HW switch/mux and the internal display+HDMI is connected directly to the onboard Intel GPU, the Nvidia GPU is just there for number crunching/acceleration. One of the ways to discover if you are able to switch is to check in the BIOS for a switch (as mentioned in the previous post) or, as an alternative, the only one I'm aware of, to load Windows on it (usually it comes preinstalled - and that's where I check before wiping it and installing Linux), install the latest Intel GPU drivers plus the latest Nvidia drivers and check in the Nvidia Driver Settings if you are able to change the video output.

I recommend to blacklist the Nouveau driver. That gives a clean situation where only the i915 is used. Unless you do gaming the i915 driver is more than adequate, even with KDE and all the bells and whistles.

To do this, create /etc/modprobe.d/blacklist-nouveau with this contents:
Code:
blacklist nvidiafb
blacklist nouveau
If you see other nvidia drivers being loaded, add them to this file as well.
