Description of problem: /etc/X11/xorg.conf is fixed during installation; start-up hangs if new video card is installed.


Version-Release number of selected component (if applicable):
Linux version 2.6.25.11-97.fc9.x86_64 (mockbuild@) (gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC) ) #1 SMP Mon Jul 21 01:09:10 EDT 2008

How reproducible:
Install FC9 on PC with mainboard (MSI) video chips, then install a new video card such as MSI-R3450 PCI Express card (ATI-Radeon chips.

Steps to Reproduce:
1. Install FC9 on PC
2. Boot and configure FC9
3. Shutdown PC, and install new video card
4. Boot PC
  
Actual results: Video start-up fails, PC monitor shows text only login.


Expected results: Expected on video failure, that autodetection of video card would be done and xorg.conf corrected.


Additional info:

The Release Notes contained a clue with its statement to delete the /etc/X11/xorg.conf file to initiate autodetection; however, there was no reference to the fact that the xorg.conf file is frozen and no explanation of what would happen if video cards were exchanged. It would be best to NOT freeze the xorg.conf file, and always permit autodetection, even at the cost of some startup time. Off and on it cost me several days to diagnose and fix this problem by deleting the xorg.conf file!! (My test PC has 4 other Linux distributions under test, and all do autodetection, and in one case, ubuntu, the system gave the option to find and install a compatible vendor supplied proprietary driver.)
