After Ubuntu 12.04 32bit and win7 64bit are installed, win7 is basically no longer used. All work is done under Ubuntu. However, there is a problem: when running Ubuntu, the notebook is overheated.

Because the notebook is a dual-graphics card (hd5650 and Intel I5 480 integrated graphics card), it is suspected that the dual-graphics card switching problem, so I found the relevant post on the UBUNTU Forum -- Summary tu11.04 ~ 12.04 atidriver installation (much simpler)

The procedure is as follows:

1. First download the driver catalyst for Linux from the amd official website.

Http://support.amd.com/cn/gpudownload/linux/Pages/radeon_linux.aspx

Now the version has reached 12.6, and the file suffix is. Run.

2. Create a folder in the home directory. The command is as follows:

Cd ~ /; Mkdir initialize st12.6

3. Put the downloaded driver catalyst file in the created mongost12.6 folder.

Installation Library:
Sudo apt-Get install build-essential CDBs fakeroot DH-make debhelper debconf libstdc ++ 6 dkms libqtgui4 wget execstack libelfg0 DH-modaliases Linux-headers-generic

4. Run the following command:

Chmod + x amd-driver-installer-12-6-x86.x86_64.run

5. Create the. Deb installation package

Sudo Sh./amd-driver-installer-12-6-x86.x86_64.run -- buildpkg Ubuntu/oneiric

6.Install the generated package
Sudo dpkg-I fglrx *. Deb

7. Generate the configuration file
Sudo aticonfig -- Initial-F

Prevent configuration from taking effect
Sudo aticonfig -- input =/etc/X11/Xorg. conf -- TLS = 1

8. Restart [required !]

9. check whether it is successful
Fglrxinfo

Next is the major event.

Dual-graphics switch (desktop and ThinkPad are not necessarily supported ):

Aticonfig -- pxl # view the currently running graphics mode

To switch the video card, enter the following command
-- Sudo aticonfig -- PX-dgpu # active and running is the Discrete mode (High Performance Mode). You must restart the video driver and activate the special effect (Just restart your computer.)

-- Sudo aticonfig -- PX-igpu # The integrated or integrated video card mode (power-saving mode) is being activated. You must restart the video driver and activate the special effect (Just restart your computer.)
