They are the ACPI method names, that are used on various Optimus-enabled systems to turn off the GPU. Because there is no standardized name for this (every vendor uses his own ACPI methods, some even cannot be turned of using ACPI), we have to to call every single method name collected on this mailing list, until one available on the system is found. The 'works!' does not necessarily mean that the battery rate will be lower - just that the method was found, and calling it resulted in no error, therefore it "works". It should probably deserve a better name and reporting, but at the time I wrote it, it was used just for testing, hence the name: "test_off.sh" :) _______________________________________________ Mailing list: https://launchpad.net/~hybrid-graphics-linux Post to : [email protected] Unsubscribe : https://launchpad.net/~hybrid-graphics-linux More help : https://help.launchpad.net/ListHelp
