Cheatcodes enable you to modify the boot parameters and are used to pass options to KNOPPIX which help get it working on difficult hardware. It just disables the ACPI backlight control on these machines whenever the kernel has indicated Windows 8 compatibility via _OSI. 2 Advanced Configuration and Power Interface (ACPI). Although this option sounds really nifty, barely any of the device drivers have been converted to the new driver model and hence few have proper power management support. In any Linux distribution, some services are enabled to start at boot up by default. conf: options thinkpad_acpi experimental=1 hotkey_report_mode=1 From then on, you can add new acpi events in /etc/acpi/events/, like /etc/acpi/events/fn-f5.
