Arch Linux NVIDIA dual-graphics Switch

20120625 update and Bumblebee are available. I have a problem with the installation. Now the computer is stable for 54 degrees on the Internet, which is very good.

This method is not easy to use. It is useless. Wait for updates...

 

Due to the miserable NVIDIA dual-graphics power management, the temperature detected by sensor in my Acer 5750g notebook continued during arch Linux

At 80 C or above, what makes me feel like...

 

First of all, I did not find an official method, but from all the evidence, vga_switcheroo is only effective for the combination of Intel and ATI graphics cards.

Invalid combination of Intel and NVIDIA graphics cards.

This document only applies to arch. For other releases, see the homepage of Bumblebee.

 

If it is not a dual-system, the simplest way is to discard the integrated video card in the bios, one step in place.

If it is a dual system, continue.

1. refer to the following content

Https://wiki.archlinux.org/index.php/Bumblebee

Use the dkms-NVIDIA driver.

In the final result, the configuration file is modified as needed, and bumblebeed startup is added to daemons.

Daemons = (... @ bumblebeed ..)

Bumblebee home page: http://www.bumblebee-project.org/

2. Configure bbswitch as the power management method, as mentioned in the previous Wikipedia

If everything is good, you can see the temperature drop after a while.

For my machine, it is reduced from 86 to 60 degrees. I can still accept this.

3. Enable and disable the independent video card.

Edit RC. conf and add bbswitch in modules.

Modules = (... bbswitch ...)

Compile/etc/modprobe. d/modules. conf

(This file may not exist. Create one by yourself. conf must be used as the suffix .)

Added:

Options bbswitch load_state = 0

For more information about Kernel Modules, see https://wiki.archlinux.org/index.php/Kernel_modules

About bbswitch refer to https://github.com/Bumblebee-Project/bbswitch

If this is done in the kernel, the independent video card will not be enabled. After you restart it, You can directly enter optirun and cannot call the independent video card. It will still go to the Integrated Video Card. You can use glxspheresProgram.

4. Check the video card status

View

[Gaohu @ Tg-arch ~] $ Lspci | grep VGA
00:02. 0 VGA compatible Controller: Intel Corporation 2nd generation core processor family integrated graphics controller (Rev 09)
0:00. 0 VGA compatible Controller: NVIDIA Corporation gf108 [geforce GT 540 m] (Rev ff)

It is a ff at the end, indicating that it has been disabled,

Or

[Gaohu @ Tg-arch ~] $ Sudo CAT/proc/ACPI/bbswitch
. 0 off
We can see that it is disabled.
