Description of problem:
When a digital output of a Flat Panel attached to a video card the graphic
installer neither the standard nor the low res version display an image. It
apparently goes out of sync. This was tested on a Dell 1503F 15" Flat Panel
attached to a GeForce 4 4200.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug the panel digital cable to the corresponding digital output of the
video card (Tested on GeForce 4 4200)
2. Turn on the computer
3. Select any of the graphical installers.
Actual Results: The screen goes blank with a message from the monitor that
tells it cannot display the image.
Expected Results: The installation screen should be visible
When using the analog conector only, or swithing to analog output if both
cables are conected result in the graphical setup been there all the time.
Just is not visible when using digital out. Had no other digital out monitor
or Digital output video card to test against it.
Could you try adding
to the boot command line, where <mode> is the native resolution of the LCD?
would be how this option would be used for a LCD with a 1280x1024 native resolution.
Unfortunately we cannot currently probe the LCD type.
