[BrianFitzgerald]

** Summary changed:

- Display Starts in 640x480 at 60Hz
+ KDE Desktop Starts in 640x480 at 60Hz

** Description changed:

  Binary package hint: kubuntu-live
  
  When the Kubuntu 6.06 Live CD is booted onto a system with an nVidia
- GeForce4 graphics chip and an Iiyama LS902U plug & play monitor, the
- display defaults to 640x480 at 60Hz and will not allow any other
- resolutions.
+ GeForce4 graphics chipset and an Iiyama LS902U plug & play monitor, the
+ KDE desktop display defaults to 640x480 at 60Hz and will not allow any
+ other resolutions.
  
- It is necessary to reduce the height of the bottom ribbon channel to
- even access the 'administator' button on the display settings menu.
+ The KDE desktop is practically unusable at this resolution.  It is
+ necessary to reduce the height of the bottom ribbon panel to even access
+ the 'administator' button on the display settings menu.
  
  It is necessary to select a different monitor and restart X before the
- correct Iiyama monitor can be re-selected to use its resolutions.
+ correct Iiyama monitor can be re-selected to use all of its display
+ resolutions and higher refresh rates.
  
  The problem is caused by no 'modeline' values in the "Monitor" section
- of xorg.conf when the Live system starts the KDE desktop.
+ of xorg.conf when the Live system starts the KDE desktop.  The
+ 'modeline' parameters are only added to xorg.conf when a different
+ monitor is selected.  This problem recurs when the Kubuntu 6.06 is
+ installed onto the hard disk of the computer with the nVidia GeForce4
+ graphics chipset and a Plug & Play monitor.
  
- Note that the Live CD works fine on another computer with a different
- graphics chipset (Intel 810) and the Iiyama LS902U monitor.  It also
- works on the computer with the nVidia chipset, but with a non-PnP
- monitor.
+ Note that the Live CD works better on another computer with a different
+ graphics chipset (Intel 810) and the Iiyama LS902U monitor.  In this
+ case (without specific 'modeline' values in xorg.conf), the i810 display
+ driver defaults to the highest of three basic resolutions (1024x768,
+ 800x600, 640x480), but only at 60Hz maximum refresh rate.
+ 
+ The Live CD also works on the computer with the nVidia graphics chipset,
+ but with a non-PnP monitor connected at start-up.  In this case, the
+ 'Default' monitor allows the same three basic resolutions and the single
+ refresh rate as above.
