Display Problem

[Terrence Oblak]

I recently installed Mandrake on my Powerbook G4.  As far as I can tell
everything is working well.  The only "problem" I have is the display.  The
PowerBook has a screen resolution of 1152 x 768, however, Mandrake is only
using 1024 x 768, so I have an inch of black space on the right hand side of
the scren.

Does anybody know of a fix?  I have tried altering the XF86Config file, but
to no avail.

I'm a Linux newbie so the more detailed you can be the better.

Thanks,
