Black screen

[Albert Farrés <albertfc@gmail.com>]

Hi list!

For a long time I've been using linux 2.6.9 in my ibook G4. Now i
compiled 2.6.12-rc4 and everething works fine, except when the screen
turns off (i.e. i don't touch nothing for 10 minutes). Before, when i
moved the mouse or press a key the screen turns on, now, whith
2.6.12-rc4, i've to press Fn+F1/F2 to turn on the screen. Any idea?

Thanks

Albert
