Greetings all, Recently I installed debian on a HP Compaq Presario V3646 laptop, everything went ok, except that the brightness adjustment buttons (Fn+F6/F7) behave strangely: if you made some brightness adjustment in X, you have to switch to a tty and then switch back to X to make the adjustment effective (same situation in tty, in BIOS and Windows it is OK). Anyone experienced similar problem? problem related to keycodes? thanks! Cheers, Deephay
