 Posted: Mon Mar 16, 2015 8:28 pm Post subject: Nvidia Discrete GPU [SOLVED] |
 |
|
I am new in Gentoo, but I have used Arch Linux for a very long time.
I have a build-in Intel GPU and a discrete Nvidia GPU.
In Arch linux the Nvidia GPU was not working when it was no used.
However, now in Gentoo, I do not use my Nvidida GPU, but it still works.

How this can be fixed because I am using a laptop and the Nvidia GPU takes too much from the battery capacity and makes the laptop hotter?
Thank you in advance![/code]

Are you able tell how your GPU is wired?
ie: Is it a Nvidia "Optimus" ( Should have a sticker proclaiming as such ), which are usually arranged such that no physical display is attached to the discrete GPU, and all the displays are attached via the integrated Intel device, via which video is sloshed between the Discrete GPU and your display via ram.
| Code: |
Typical Classical Structure: Software → Nvidia → Display
Optimus configuration:
Standard Behaviour: Software → Intel → Display
"Accelerated" Behaviour: Software → Nvidia → Ram → Intel → Display

| My Nvidia GPU is not connected to the display. My integrated Intel GPU is connected and the way I used the Nvidia GPU in Arch was that I set the output of the Nvidia to go to the Intel GPU. I suppose that my Nvidia GPU i snot Optimus on the sticker only Nvidia GeForce is written. |

Thank you for the help with bumblebee, I did not know it. I read the links you send. However, I want to use my nvidia card with the nouveau driver. So i read Prime (https://wiki.archlinux.org/index.php/PRIME). XRandR detects only one provider and there is not /etc/X11/xorg.conf.
How can I fix that?
Thank you in advance!!! |
