Thomas Christensen, bugzilla is legacy, and largely ignored by upstream developers. As well, it holds none of the information requested by upstream, as previously and fully documented to you in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1181927/comments/21 . Instead, you would want to utilize the kernel.org format and repost to the linux-acpi mailing list with the latest mainline kernel results.

The brightness up down buttons shows the overlay brightness icon going up and down but it does not change the brightness (backlight). I have tried adjusting the kernel options acpi_osi=<x> and acpi_backlight=<y> (that did work with 12.10) to make it work but to no avail.
