apport information
** Tags added: apport-collected saucy
** Description changed:
On an Acer Travelmate 8481TG using the default-config, the screen's
brightness can't be controlled (with Fn+cursor-key), altought the event
is recognized (and displayed in a popup in the upper right corner of the
screen).
With the kernel-parameter "acpi_backlight=vendor" the brightness-control
works (with Function-Key), but then another problem arises: When the
screen is switched of via DPMS (automatically after 10 minutes, or
manually with "xset dpms force off"), it can't be reactivated by moving
the mouse or pressing any key (as without acpi_backlight=vendor),
instead the screen has to be reactivated with the brightnes-control-keys
(which does not work while the screen is locked).
