I have wanted to know can you make switching on the Inspiron 7520 using an AMD HD 7730m and an Intel 4000hd.

Dell sent me two scripts:   Script 1:

#turn off discrete graphics card
echo '\_SB.PCI0.PEG1.GFX0.DOFF' > /proc/acpi/call
# turn it back on
echo '\_SB.PCI0.PEG1.GFX0.DON' > /proc/acpi/call

  Script 2:

sudo apt-get install git
git clone link Intel Ubuntu drivee
cd acpi_call
make
sudo insmod acpi_call.ko
./test_off.sh :

Basically, what this is trying to do is to shut down the card I don't need but I am not good enough to make those script work. May I have your help?

git clone link Intel Ubuntu drivee doesn't make sense. After git clone there should be a URL to the repository location, which will probably end with /acpi_call.git. –  Chris Morgan Aug 22 '13 at 2:40
