laptop brigtness up/down buttons issue


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?

Cheers.

No help for you, except a possible clue. Kubuntu 7.1 used to control display brightness, but updates have taken brightness control. Computer is IBM Thinkpad 9450A38 with all Intel 945 system. No idea if problem is in KDE, Ubuntu or kernel.
Perhaps install of Linux revision from last summer might help localize problem?
