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. Aftergit clone
there should be a URL to the repository location, which will probably end with/acpi_call.git
.
