Description Chuck Dubuque 2010-05-19 15:35:08 UTC
Description of problem:
This was an issue I had with earlier versions of F12 that was eventually fixed. F13 reintroduces the issue. Have a Lenovo X200 laptop with an external VGA and external Displayport monitor attached (dual head config). At login, the login screen is not visible/corrupted. You have to enter the password blind. After login, screens display correctly.

Version-Release number of selected component (if applicable):
xorg-x11-drv-intel-2.11.0-4.fc13 (x86_64)

How reproducible:

Steps to Reproduce:
1. Reboot or log off
2. Try to log on
Actual results:
During reboot, only the Displayport screen shows any picture (VGA is no-signal). When reboot is complete, Displayport goes to no signal. VGA screen shows a corrupted slice of the login screen squashed to the left 1/3 of the screen. You can't see the login dialog box, so you have to blindly hit enter and enter the password. If something goes wrong, you can't tell. 

Once the login is accepted, both monitors have picture an appear normally.

Expected results:
When this was fixed in F12, during reboot both screens (VGA and Displayport) would mirror each other, and show full picture throughout reboot process. At login, the primary screen (Displayport) would show the login screen in full so you could see the primary username and choose another if you wanted. Once login was complete, you would see both screens normally.

My colleague has similar problem with his laptop and an external monitor, so I
will answer those questions:

$ cat /etc/X11/xorg.conf
cat: /etc/X11/xorg.conf: No such file or directory

other files will follow.

Comment 7 Fedora End Of Life 2012-08-16 16:56:30 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
