Looking back at your last comment, this sounds like the core of the issue is that there are two interfaces present that are trying to control brightness. Could you try booting with the kernel boot parameter of "acpi_backlight=vendor" which should disable acpi_video0 leaving intel_backlight. Does this improve the issue, or cause additional problems? Also, now that I've set a package please run "apport-collect bug#" so that any logs that may be relevant get attached here. If "acpi_backlight=vendor" either doesn't help, or causes weird flickery issues, there are a few other ways to try to cut the number of interfaces down to one.
