Description Joachim Frieben 2006-04-02 14:54:11 UTC
Description of problem:
A fresh install of FC6/rawhide is performed on an IBM ThinkPad
T23. The lid is closed, and an LG1710B 17" TFT monitor is
connected to the computer by means a docking station (VGA
output). When the installer switches from text to graphical
mode, the monitor remains blank and goes to power save mode
after a short period of time ("resolution=800x600" was added
as boot argument!).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start installer from "boot.iso" CD.
2. Enter basic information in text mode, including the
   screen mode ("resolution=800x600").
Actual results:
The monitor turns blank.

Expected results:
The Fedora graphical installer should have appeared on
the screen.

Additional info:
It is still possible to switch to a text console. It is also
possible to obtain a working graphical installer by switching
off the monitor and opening the lid before switching on the
notebook. The "XConfig.test" shows that the first screen mode
has a resolution well beyond the capabilities of the monitor
which prevents it from synching with the VGA signal. The actual
resolution is "1920x1200"!!!

This used to work for previous releases of "Fedora Core" including
"FC5" and early "FC6/rawhide".

Comment 3 Joachim Frieben 2006-05-05 08:22:21 UTC
Works again for rawhide as of 2006-05-05.
