Linux Laptop install dual graphics driver (Intel+nvidia)

This article is unique in order to improve the graphics performance of Linux and reduce power consumption.

The system I use is the Fedora Xfce x64, which ensures the latest version before installing the driver.

It is best to install GCC, kernel-devel and other software packages, I am not sure later will be dependent on automatic installation.

Install Intel set driver, you can go to the Intel official website to find, or direct access to https://01.org/linuxgraphics/

This address is provided by Intel, click Download on the left side of the page to find the required files.

Thanks to the direct provision of the Fedora RPM package, download and install.

This bag is small, just a repo and a helper program.

Click "Application menu, set->intel Graphics Installer for Linux" To run the wizard program

The program detects the system environment, and if you are prompted for something that is missing and then manually installed, you only need to install PackageKit on my current system.

Follow the wizard step-by-step, and it's easy to install.

Install it and remember to restart it. In my notebook I will find that the error and warnning are not there before the logo on the boot.

Install Nvidia single display driver, reference help Http://fedoraproject.org/wiki/Bumblebee

Here I install bumblebee, also install Nvidia's closed source drive, but the channel is not the same.

According to help I toss for a long time, re-installed two times the system, only to find out the correct method. (The reload is due to the crash when restarting)

Help Page said a lot of steps to do only the crash, so please refer to my installation procedures.

The two Yum repository mentioned in the direct installation page , now the latest version is 20.

Then install Bbswitch, Bumblebee, Bumblebee-nvidia.

The download is slow, and if necessary, keep the backup.

The nvidia X server settings option can be found in the Application menu, settings, after reboot.

However, this option is not available and will prompt you to not load NVIDIA drivers after running, regardless of the tool.

Or, open the program by executing Optirun nvidia-settings-c: 8来.

The lsmod can be used to determine that the nouveau of the system itself is not loaded (bumblebee modified the boot parameters of grub).

Available through Optirun Glxgears-info | grep "Gl_vendor" to see if a single display is used (the fan will accelerate when testing).

The device status can be viewed through the Lspci|grep-i VGA, and in the idle state you can see the video card information and finally the Rev FF Sleep state.

You can specify to run a program by Optirun.

This installs and then continues to install dkms to ensure that the graphics driver is updated while the system kernel is updated.

Because there is no big 3D game in Linux itself, so I do not have to use the bumblebee, that is, in order to close the unique display.

Can not be directly disabled in the BIOS, otherwise windows, I am a dual system.

The next steps are optional and unwanted friends do not have to install.

Installs TLP, TLP-RDW, this is the notebook energy-saving tool, automatically adjusts each hardware power consumption, does not have the manual configuration, the default is good.

Installing the Xbacklight for adjusting the notebook brightness

with a script http://forum.ubuntu.org.cn/viewtopic.php?p=3056691, allows the system to automatically remember the screen brightness

My shortcut keys are set to Win+up and Win+down, so I don't use FN anymore.

Note Xbacklight cannot adjust the screen brightness if the Intel set driver is not installed.

The heat of the notebook and the power consumption problem solved.
