Bug Description
I installed Dapper Flight 3 on an iBook G3 600 MHz with an ATI Rage 128 video card. The video displays only the left 1/3 of the screen. After some research, the resolution was set to 640x480 which is incorrect; it should be 1024x768. The xorg.conf file is setup to display on that resolution as 1024x768 is the only resolution in the screen section. The problem is that the monitor is not identified correctly. There is no HorizSync or VertRefresh specified in the monitor section, so, I assume it falls to a "safe mode" of 640x480.
By adding the following to the monitor section in my xorg.conf and restarting gdm, the display was correct:
HorizSync 30-70
VertRefresh 55-65

I had similar behaviour on a Thinkpad A22p with an ATI Rage 128 video card with the Flight-4 Live CD. The display was very messed up and unusable.
I compared the xorg.conf file from Dapper with my Breezy version and the significant differences are that the Horizontal Sync and Vertical Refresh are
missing.

< HorizSync 28-80
< VertRefresh 43-60
Breezy was also loading GLCore

< Load "GLcore"
I booted the live Dapper FLight-4 CD. Went to a virtual console. Modified
the xorg.conf file to contain the above 2 parameters and load "GLCore". Killed
X via the command line and it worked fine
