I am quite late on this subject, but I found several points that that may be relevant:
- I have two different laptops that have the same symptoms as descibed here: one is a Toshiba Satellite T130-11U (more than 3 year old but still working) the other is a Dell Inspiron 15 3521 (brand new) - Both are now used with Ubuntu 13.04 32 bits (low memory => I prefer 32 bit versions). so I confirm the bug is still present in versions 13.04 ... i386 - on both I noticed that I can read and modify the backlight value, which allows the scripted modification... - I am seeking for a more comfortable way to modify it. replacing the standard, not working key association is my first idea. I found that the keycodes for lowering/increassing brightness are respectively 232 and 233. - I also found that these keycodes are intercepted by gnome-settings- daemon (google...), but how should it be modified ??? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1021437 Title: gnome settings picks the wrong file in /sys/class/backlight to change the brightness Status in “gnome-settings-daemon” package in Ubuntu: Incomplete Bug description: In my laptop i have 2 entries under /sys/class/backlight * acpi_video0 * toshiba if if echo to acpi_video0 the brightness works, if i do to toshiba it does nothing. Gnome seems to only pick toshiba and there is no way to tell it to use acpi_video0 instead. BTW i have a toshiba laptop so i assume the toshiba entry is correct.
