Getting the best from my Powerbook's screen

[glabelle at optimized.org]

Hello all,

I have a 17" Powerbook G4 that runs Ubuntu Breezy with a 1440x900 resolution
without any problem.

MOL runs fine in the wanted console but I am unable to set the 1440x900
resolution properly. When I try a lower resolution everything works fine but I
would like to get the best from my screen even in MOL.

Any idea?
Many thanks for your time and help.
