I have an ATI Technologies Inc 3D Rage I/II 215GT [Mach64 GT] (rev 48)
(Class 0300: 1002:4754 (rev 48)) graphics adapter and a non DDC-Monitor.
When following the suggestions of the installer, startx fails because of
"No valid modes found."
After using Xconfigurator all things are fine.
Which installer did you run (TUI or GUI)?
This defect is considered MUST-FIX for Florence Gold release
Because I have changed the graphics adapter I am unable to perform checks if the
bug is fixed or not. Sorry...
