Lenovo Y470 installs Ubuntu to solve problems such as dual graphics fever

UBUNTU14 There is no problem solving the video card, there will be such a problem

1. Power consumption particularly fast, fan turn

2. The mouse key head display has the problem, the flicker, simply cannot use, easy to get stuck can not find the mouse arrow where, the feeling graphical interface display also has the problem, is unstable

After solving the problem with the graphics card, these problems will be solved

2015.04.22

Ubuntu 12.04 (also for system versions such as UBUNTU14) The heat is super powerful solution (power consumption particularly fast) ( Nidia the dual graphics switching technology is called Optimus , but only in Win7 , Vista under implementation, Linux there is no corresponding technology under the / Of course there are no apples. This led to the independent graphics card has been started, video card heating, fan, but not for normal work input, usually win7 under the battery can use about 4 hours, to the Ubuntu you can only use the 2 more than one hour, so the problem needs to be solved) ( Linux The unique support for notebooks is pretty poor, and my Y470 : The light is turned on, the lights off, is integrated graphics, but only in Win7 under the use, not in Ubuntu under use)

Since Nvidia introduced Optimus Technology, Linux Systems also have a Bumblbee plan, can also support the N-card dual graphics switch, and Ubuntu such a popular system will certainly support!!

Replaced Ubuntu 12.04, try to install Bumblbee, at that time according to the online tutorial, installed after the discovery temperature is still very high, fan sound is still so big, then go to UBUTNU Chinese forum to check, just know, originally Lenovo notebook special, temporarily not support Bumblbee, alas, It cost a half a day, this depressed. I have never looked again. Today, that is, November 23, suddenly thought, in the BIOS should be able to prohibit the independent graphics card, the evening after home hurriedly open the computer to see, I have a go, this bios and Sony so like, so simple, unexpectedly there is no about the graphics card of that one, then go online search, it seems to be y480p only supports bios off of discrete graphics cards.

Of course, command what do not understand, first solve the problem, say:

I installed the system is Ubuntu 12.04, notebook for Lenovo Y470,core i5, video card for gt550m.

1. Due to the installation of the system prior to the choice of installing the system recommended limited driver. Therefore, the restricted driver must be removed first.

Command: sudo apt-get purge nvidia-current

2. Add the source of the Bumblebee

Command: sudo add-apt-repository ppa:bumblebee/stable

If you are using an Ubuntu 11.04 or older version of the system, the driver you want to update runs

Command: sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

3. Running

Command: sudo apt-get update (some hints may appear, giving the impression that something is wrong, actually not, continue to execute, and continue typing the following command just fine)

4. Install bumblebee with Nvidia private drive

Command: sudo apt-get install bumblebee Bumblebee-nvidia

5. Join the Bumblebee Group

command: sudo usermod-a-G bumblebee $USER

6. May need to use 32-bit library so run

Command: sudo apt-get install virtualgl-libs:i386 libgl1-mesa-glx:i386 libc6:i386 (some of which I have already installed before I made the AVD, So I'm going to execute this command here and I'll prompt you to install it or something else, and it won't affect you.

7. Restart the machine

The following is the Hackish solution for Y470 and Y570. The original author requested to remind the user that this is hackish solution, improper installation may damage the machine. Please take your own discretion. I have done the work, the machine is OK, but still want to emphasize.

8. If git is not installed on the machine,

Command: sudo apt-get install git (I've already installed it)

9. Download the hackish version of the original author (Peter Lekensteyn) Bbswitch

Command: Git clone git://github.com/bumblebee-project/bbswitch.git-b Hack-lenovo

This command is executed under that directory, which directory the Bbswitch is downloaded to

10.

Command: CD Bbswitch

mkdir/usr/src/acpi-handle-hack-0.0.1

(The execution of this statement is expected to prompt for no permissions, if it is the root account, there should be no error, but Ubuntu to reduce the difficulty of Linux, the default is to disable the root account, to enable the root account, the command is sudo passwd root, Set the root password, and then switch to the root account to execute it without problem.)

sudo cp Makefile acpi-handle-hack.c/usr/src/acpi-handle-hack-0.0.1

sudo cp dkms/acpi-handle-hack.conf/usr/src/acpi-handle-hack-0.0.1/dkms.conf

sudo dkms add acpi-handle-hack/0.0.1

sudo dkms build acpi-handle-hack/0.0.1

sudo dkms install acpi-handle-hack/0.0.1

11. If all of the above are normal, then for Ubuntu and Debian users can run

Command: Echo acpi-handle-hack | sudo tee-a/etc/modules

sudo update-initramfs-u

12. Restart the machine.

13. Typing commands at this time

command: lspci |grep-i VGA

You should see that the Nvidia card information is at the end of Rev FF, indicating that it has been disable.

14. View Effects

Command: Optirun glxspheres64

You can see the 3D test screen. This is the success of Lenovo Ideapad y470/y570.

Fixed an invalid bug when the original bumblebee was installed.

It's like the/sys/kernel/debug/vgaswitcheroo/switch directory is gone.

Using this method to successfully install the Bumblebee, but also successfully turned off the single display (fan no longer turned so much, the heat is not in the words, battery life significantly longer) (in short, in strict accordance with this operation to be good, will be successful)
