Just got a Z930 and cannot change display brightness at all. Set acpi_backlight=vendor in /etc/default/grub which resulted in displaying a widget that shows the "current" setting for display brightness and the change when I press FN-F6 or FN-F7 but the display itself remains at full power.
Creating /etc/udev/rules.d/00-tosh-backlight.rules and resulted in a black screen at login that I could not change at all.
