Apple 15" Studio Display

[Nakia L. Jackson]

I am running Yellow Dog 3.0 on a partitioned G4 466.  I have 9G 
partitioned to LINUX.
Everything seems to work wonderfully except, using my 15" Apple Studio 
Display,
I get an alignment problem and my screen has about an inch of space on 
the left hand side where if I move my mouse or anything too far to the 
right it will show up in this space on the left hand side.  Has anyone 
else come across that?  It's almost like it's a Vertical/Horizontal 
problem, but from what I know, these monitors don't have 
horizontal/vertical settings.

help...
