Intel and AMD no-mux switchable graphics
I'm trying to configure my Ubuntu for switching between AMD and integrated Intel graphics (I don't mind restarting my computer to acomplish the switching each time) per http://askubuntu.com/a/196644/ Unfortunately I encountered an error and I'm too n00b to punch through it further. In Solution1: After ~/acpi_call$ chmod a+x test_off.sh I get the following error: chmod: cannot access `test_off.sh': No such file or directory . No other errors up to this point.
Indeed, the location does not contain the file. How do I proceed then?
