Bumblebee conflict problem

Hello everyone I try to install the non-free nvidia drivers to run games correctly with the command:

'sudo mhwd -a pci nonfree 0300'

But each time I get the return:
'> Using config 'video-hybrid-intel-nvidia-440xx-prime' for device: 0000:00:02.0 (0300:8086:3e9b) Display controller Intel Corporation UHD Graphics 630 (Mobile)
Error: config 'video-hybrid-intel-nvidia-440xx-prime' conflicts with config(s): video-hybrid-intel-nvidia-430xx-bumblebee'

which prevents me from installing what I want and when I try to uninstall Bumblebee driver it comes out:


Removing video-hybrid-intel-nvidia-430xx-bumblebee...

help me please i can't take it anymore

I'm no expert with graphics, or anything for that matter, but maybe try uninstalling linux-latest-bbswitch and linux-latest-nvidia-430xx first.

Just in case you haven't read it:

You have installed 'linux-latest' and its accompanying module packages
(linux-latest-nvidia-430xx & linux-latest-bbswitch).
Remove that stuff and carry on.
(make sure you do have some kernel installed though :wink:)


It works well thanks lot <3 3 days i've crawl all internet to this solution x)

You're welcome :smile:

Do you know that video-hybrid-intel-nvidia-440xx-prime allows you for more than bumblebee?

Basically what it does, it makes the desktop run on Intel but has also Nvidia powered on and you can access it by adding environmental variable:


This works identical as on bumblebee, so instead primusrun appname, you just use the above command with appname, like:


but you won't have bumblebee limitations.

There are pros and cons of each solution. Your current (assuming you haven't installed bumblebee yet) setup allows you for full usage of Nvidia, so Vulkan is working, With bumblebee Vulkan is not eligible, so Proton games will have to use DX9 with opengl, so basically the old wine way of launching games. Many modern games like Witcher 3 won't run at all and so on.
The con of your current hybrid mode is: nvidia is powered on so it drains energy (bad for laptop using battery) all the time, even if you are not using Nvidia. Secondary monitors also won't work.

Bumblebee is basically an obsolete solution that has little point with DXVK/Proton solutions.

If you want to manage your GPUs and energy, use either optimus-manager or optimus-switch:
