Brightness not working on Lenovo Yoga 11s

http://www.linuxquestions.org – I just installed Linux Mint 16 on my Yoga 11s, but for some reason, the brightness doesn't work right at all. On boot, the brightness is set to 00, which makes the display completely blank. The only way I can use my system is to put the command "acpi_backlight=vendor" into grub. This will allow me to see everything, but I am still unable to control the brightness using the control keys or the applet. Strangely, I can change the brightness via the terminal by using command "intel_backlight XX," where XX is a number. I would like to be able to control the brightness as norma (HowTos)
