Optimus Laptop, how to always use NVIDIA on Wayland?

asked 2018-12-13 22:51:06 -0500

I have 2 GPU in my laptop (iGPU and dGPU)

I want to disable iGPU (HD Graphics) and always enable/use dGPU (NVIDIA GT 710m). I don't care about battery life.

If possible, I'd like to use Wayland instead of XORG (My Xorg is broken because installed nvidia driver improperly).

First of all beside of gaming, (maybe) using CUDA applications and (maybe) using gpu-accelerated video decoding/encoding you won't get much from your NVidia gpu. If you don't need any of the above then with Intel integrated gpu you'll get smoother and more stable experience with Linux in general and Wayland in particular.

Simplest way to disable iGPU is from BIOS/UEFI setup -- if you have an option for that.

I don't have the option. When I run my steam with "Dedicated Graphic" it runs slower than the normal run. (Which in case the Intel HD wins)

Well, I'll try getting a new PC then.

@bidipeppercrap, I don't have an Optimus laptop (just desctop PC with nvidia gpu) so I can't give you definitive answer, but as far as I understand to use Nvidia on Optimus you have to switch it on somehow (by default Intel gpu is used). As you can't turn Intel gpu off in BIOS and you already installed negativo's drivers, it seems that your best bet is to use Bumblebee.

Please check this question, in my comments and answer I gave a number of links about Optimus I think you can get all the info from.

Please check this answer to your question in Bumblebee FAQ. I think you should start your research from there.

As for improper nvidia install -- check this answer in rpmfusion's how-to.

Regarding wayland and nvidia -- Wayland doesn't work by default on negativo17's drivers (checked personally, the option just is not there, it's also mentioned in the FAQ), but I've encountered mentions (see this comment for FedoraMagazine article, for example) that they can -- with rpmfusion's packages maybe?

It is better to install the program to support the graphics card.

 https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/
 https://www.geforce.com/drivers

For more information, please refer to the following resources to install the Linux installation materials. The built-in graphics card like a internal video can be changed by BIOS to off , also use internal PCI-E graphic card.

Optimus is able to effectively implement two graphics capabilities and automatically configure the settings according to the application, and the driver must be provided by the graphics manufacturer for proper operation. However, due to the complexity of certain environments and settings, not all operations are perfect.

Other users are also raising such issues, and because of the complexity of the setup and the support and operation of the driver, please use it based on the information mentioned.

Even with modern operating systems like a fedora, the acceptance of all hardware is much more likely to be solved if the number of users increases in an open source Linux, but it can not support the hardware completely and provides the environment foundation that users can develop to solve the problem There is. If you've resolved these issues, please let us know.

@simmon, I think it's better to advice on installing drivers from repositories (rpmfusion or negativo17), not directly from Nvidia. It's easier, cleaner, has less chance to create problems, imho.

No option in the BIOS. I also installed the driver from negativo17
