Hello.

I have 2 graphic cards in my laptop: * One from Intel HD. * One from Nvidia.

It's a nvidia-optimus laptop as you can see.

I want to disable Nvidia graphic card permanently at Fedora 23, is it enough to remove the package xorg-x11-drv-nouveau to do this, or I have to do something else?

Thanks.

I don't think removing the driver is enough to disable the card. It should still be draining your battery. You probably have to switch it off explicitly. EDIT: Use powertop as suggested by @snowolfe in a comment below to find out whether your graphics card really is draining power. If it isn't you can stop here.

If your card is still running:

Can you disable the card from BIOS/(U)EFI?

Otherwise you could try one of these links:

You just have to get the PCI device ID/path of your graphics card. Use lspci and consult man lspci for details.

I could be wrong, but I don't think it is necessary to mess around with this unless you can see that the device is still using power - powertop tells me it isn't on my machine (or if it is, it is so small that it is not being reported). Without the driver to activate the device, it doesn't get used and as such, doesn't consume power.

As I noted above, you may need to make sure that it is not started during the boot-cycle (from the embedded initramfs driver), just in case that leaves it consuming some power.

I permanently disable the Nvidia-optimus card on my laptop because I have no need of it - I use the steps outlined here. I have upgraded to Fedora 23 since this post and as far as I can tell, using various monitoring tools, it is inactive (and not consuming power as a result).

As an aside - your BIOS may allow you to disable the Nvidia card, but neither of the laptops I have offer this BIOS option; worth checking though.

I know that but I am asking a specific question here: is removing that package enough or not?

If you have also updated your initramfs to remove the embedded driver (see steps 3 & 4 from my link above), then (probably) yes; but I am not 100% sure.

powertop shows 0.0% usage on my system - which is what I wanted to achieve.
