Lenovo Y460 dual graphics card in Ubuntu

I have been plagued by the problem of how to disable the dual-graphics card model in Ubuntu for a long time. The solution to the network searching is more reliable by the method provided by southwolf, but there are some minor bugs.

I have been plagued by the problem of how to disable the dual-graphics card model in Ubuntu for a long time. The solution to the network searching is more reliable by the method provided by southwolf, but there are some minor bugs. The original article is as follows:

--------------------------- The legendary split line -------------------------------------

Y460 and other dual-graphics card models use integrated graphics card methods in Ubuntu 10.04:
Set Switchable Graphics in BIOS, install 10.04, do not install atidriver [LINUX community www.LinuxIDC.com]

1. Update the kernel to 2.6.35.
# -- Add the kernel PPA source --#
Sudo add-apt-repository ppa: kernel-ppa/ppa & sudo apt-get update
# -- Update the kernel --#
Sudo apt-get install linux-headers-2.6.35-22 linux-headers-2.6.35-22-generic linux-image-2.6.35-22-generic linux-maverick-source-2.6.35
Note: updates from the PPA source may be slow !! There are many things to download !!
If the network speed is slow, you can drag it down with thunder (=. = #) and install it in ubuntu...

2. Install the acpi_call Module
Sudo apt-get install git
Git clone http://github.com/mkottman/acpi_call.git
Cd acpi_call
Make

Sudo insmod acpi_call.ko
./Test_off.sh
If an OK message is displayed, it indicates that the exclusive display has been disabled.
3. Add the script for disabling the exclusive display to the startup Item.
Sudo gedit/etc/rc. d/rc. local
Join
Insmod/your path/acpi_call.ko
Sh/your path/test_off.sh

--------------------------- Another split line -----------------------------------

Ubuntu10.10 2.6.35 perfectly supports dual graphics cards. Generally, you do not need to enable exclusive display. To reduce fever and prolong the standby time,
We recommend that you disable exclusive display in Ubuntu.

1. Install the acpi_call Module
Sudo apt-get install git
Git clone git: // github.com/mkottman/acpi_call.git
Cd acpi_call
Make

Sudo insmod acpi_call.ko
./Test_off.sh
If an OK message is displayed, it indicates that the exclusive display has been disabled.
2. Add the script for disabling the exclusive display to the startup Item.
Sudo gedit/etc/rc. d/rc. local
Join
Insmod/your path/acpi_call.ko
Sh/your path/test_off.sh

------------------------- This split line is followed by longriver revision ---------------------------

1.10.04 the kernel cannot be upgraded to 2.6.35 according to his method. This may be due to incorrect methods or other problems.

2. Follow the southwolf method in step 1 under 10.10 and the dedicated indicator is off! Ecstasy! The second step immediately discovers the bug *~ *...
1) After sudo gedit/etc/rc. d/rc. local is edited, it cannot be saved. The system prompts that this path is not available! So ls/etc does not exist. Is it a new one or... and slow! There is an rc. local file under/etc! Try editing... it's good.
2) supplement: insmod/home/your name/acpi_call/acpi_call.ko
Sh/home/your name/acpi_call/test_off.sh
Such writing should be more conducive to cainiao operations like me, with less detours!
