F = 42 & t = 350772 & sid = 95f2a3cf0ccdf4c3a77f65f7138682b6 after ubuntu 12.04 32bit and win7 64bit are installed, win7 is basically no longer used, and all work is done under win7. However, there is a problem: when running ubuntu, the notebook is overheated. Www.2cto.com 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 install the atidriver (much simpler) as follows: 1. first of all to download the AMD official website linux version of the driver catalyst http://support.amd.com/cn/gpudownload/linux/Pages/radeon_linux.aspx now version has been out of 12.6, the file suffix is. run2. create a folder in the home directory. the command is as follows: cd ~ /; Mkdir ready st12.63. put the downloaded driver catalyst file in the created ready st12.6 folder. 4. run the command chmod + x amd-driver-installer-12-6-x86.x86_64.run5 below. create. 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 *. deb7. generate the configuration file www.2cto.com sudo aticonfig -- initial-f to prevent the configuration from being effective sudo aticonfig -- input =/etc/X11/xorg. conf -- tls = 18. restart required!] 9. check whether fglrxinfo is successful

Next, the dual-graphics switching (desktop and thinkpad are not necessarily supported): aticonfig -- pxl # to view the currently running graphics card mode, you need to switch the graphics card, enter the following command -- sudo aticonfig -- px-dgpu # The active and running mode is the discrete mode (high-performance mode). you must restart the video driver and activate the special effect (just restart the computer) -- sudo aticonfig -- px-igpu # integrated or integrated graphics mode (power-saving mode) is activated and running. you must restart the video driver and activate the special effect (restart your computer) by owen-beta.
