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
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?
