Alors mon PC est un Asus N53SM en dual boot avec Fedora 20 (Installé via FedUp depuis F19) et Windows 7

Et voila ce que donne dmesg | grep acpi

Aucune réaction quand je fait FN+F5 ou FN+F6, mais parfois j'ai une erreur de unit:

Mais bon de loin ça c'est normal non ?

Petit UP pour dire que j'ai reformaté, et installé un F20 tout frais. mais le problème est toujours la, phénomène étrange, quand une application est lancée en plein écran, ca marche !

EDIT: Je peux peut etre préciser que j'ai installé Bumblebee pour mon chipset optimus, je sais pas si ça pourrait potentiellement influer sur quelque chose

Alors j'ai acpi_video0, acpi_video1 et intel_backlight

Et ta commande fonctionne.

Non on dirait meme que la touche est reconnue, mais que la luminosité descend puis se remet directement, comme si F5 était mappé 2x

Je te donne de mes nouvelles, mais a mon avis on est sur la bon piste, je viens de me rendre compte que F5 tout seul écris ca "~"

Alors j'ai exécuté

xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'

qui me donne quand j'appuye sur F5:

keycode 71 = (keysym 0xffc2, F5), state = 0x10
keycode 71 = (keysym 0xffc2, F5), state = 0x10

ce qui est donc correct, la dessus je dois installer gconf-editor (fait) et aller sous /apps/gnome_settings_daemon/keybindings

Or sous apps dans gconf-editor je n'ai que "aisleriot" et "gconf-editor" :/
