You received this bug notification because you are a direct subscriber
of the bug.

Status in “linux” package in Ubuntu: New

Bug description:
Cannot change bringhtness at all.
The Fn keys seem to work properly because they make appear the
brightness indicator on the upper right corner of the screen, but
nothing changes actually.
The panel brightness applet has the same behaviour: it seems to work but
nothing changes.
When booting with "acpi_backlight=vendor" grub option no change is
noticed on the screen, but the brightness applet says "cannot get laptop
panel brightness" instead of the (supposed) brightness level, when the
mouse pointer stands over it.
