I don't think the kernel is related, because I tested with kernel 3.5(it worked well with Ubuntu 12.10, with "acpi_backlight=vendor") and had the same problem. I'm using 13.04 and Acer Aspire 4332. If I do "sudo su" and "echo (brightness value) > /sys/class/backlight/intel_backlight/brightness" in the command line it works. The Fn ← & → keys worked only if add "acpi_osi=Linux" to GRUB_CMDLINE_LINUX_DEFAULT. However I couldn't set bright from System Configuration.
