Here is my info. OS:Ubuntu 11.04 Kernel:2.6.38-10-generic (I check it out by using the "uname -r") Laptop:Lenovo Idlepad V460 Graphic1:Intel GMA Graphic2:G310m (I don't think it support the Optimus,because I bought this laptop in 2009 Jun)
Hi,recently I have tried the Ubuntu 11.04,that feels good.But what bother me is that I can't switch to my integrated graphic card.My discrete graphic card emits a lot of heat and draws a lot of energy.I have done a lot of research to figure it out,but it doesn't work.Whenever I watch the video on You-tube,I can feel the heat from my laptop fan.It must be the discrete graphic card is still working. I have tried 3 methods. 1.acpi_call:It doesn't seem to work. 2.Bumblebee:The same to the above. 3.vgaswitcheroo:Can't find the file or directory. If you want more specific info,please contact me,I will reply as soon as possible. Thanks a lot. Here is the methods I have used. ---------------------------------------------------acpi_call----------------------------------------------------------------- INSTALL sudo apt-get install git git clonehttp://github.com/mkottman/acpi_call.git cd acpi_call make USE(do once after you start your computer) sudo insmod acpi_call.ko sudo bash ./test_off.sh OUTCOME before: root@fish47-Ideapad-V460:/home/fish47# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) 02:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310M] (rev a2) root@fish47-Ideapad-V460:/home/fish47# lshw -c video *-display description: VGA compatible controller product: GT218 [GeForce 310M] vendor: nVidia Corporation physical id: 0 bus info: pci@0000:02:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:bd000000-bdffffff memory:c0000000-cfffffff memory:be000000-bfffffff ioport:2000(size=128) memory:bcf00000-bcf7ffff *-display description: VGA compatible controller product: Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 12 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:42 memory:f2000000-f23fffff memory:d0000000-dfffffff ioport:1800(size=8) after: Trying \_SB.PCI0.P0P1.VGA._OFF: failed Trying \_SB.PCI0.P0P2.VGA._OFF: failed Trying \_SB_.PCI0.OVGA.ATPX: failed Trying \_SB_.PCI0.OVGA.XTPX: failed Trying \_SB.PCI0.P0P3.PEGP._OFF: failed Trying \_SB.PCI0.P0P2.PEGP._OFF: works! root@fish47-Ideapad-V460:~# lspci | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 12) (prog-if 00 [VGA controller]) 02:00.0 VGA compatible controller [0300]: nVidia Corporation GT218 [GeForce 310M] [10de:0a75] (rev ff) (prog-if ff) root@fish47-Ideapad-V460:~# lshw -c video *-display description: VGA compatible controller product: Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 12 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:42 memory:f2000000-f23fffff memory:d0000000-dfffffff ioport:1800(size=8) ------------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------bumblebee-------------------------------------------------------------- INSTALL sudo bumblebee-uninstall sudo apt-get install ppa-purge sudo ppa-purge ppa:ubuntu-x-swat/x-updates sudo ppa-purge ppa:xorg-edgers/ppa sudo apt-add-repository ppa:mj-casalogic/bumblebee sudo apt-get update sudo apt-get install bumblebee USE bumblebee-configuration OUTCOME root@fish47-Ideapad-V460:~# bumblebee-disablecard-on-powerup /usr/local/bin/bumblebee-enablecard: 1: �: not found /usr/local/bin/bumblebee-disablecard: 1: �: not found ------------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------vgaswitcheroo---------------------------------------------------------- USE sudo su echo IGD > /sys/kernel/debug/vgaswitcheroo/switch echo OFF > /sys/kernel/debug/vgaswitcheroo/switch OUTCOME bash: /sys/kernel/debug/vgaswitcheroo/switch: no such file or directory -------------------------------------------------------------------------------------------------------------------------------
