Description Simone Marchioni 2009-02-20 11:53:48 EST
Description of problem:
Installed Fedora 10 on a Compaq Presario 2100 and updated to last packages.
The video card is functioning correctly on the integrated LCD monitor, but the external VGA output doesn't work.
The integrated video is an ATI Radeon Mobility U1 (IGP320M)

Version-Release number of selected component (if applicable):
xorg-x11-drv-ati 6.0.0-2

How reproducible:

Steps to Reproduce:
1. Connect an external CRT or LCD monitor
Actual results:
The notebook "feels" the external monitor connected (the screen resolution utility shows both the integrated LCD and the external monitor), but the screens shows "no input signal"

Expected results:
The external monitor should work

Additional info:
Tried 3 different LCD monitors and a CRT monitor but obtained the same result.

Any resolution to this?

I have a similar problem on F11  
Exactly as describe in bug after the login to Gnome.
Prior to login I can see everything the laptop displays on the external monitor, once I login it goes black.

After fiddling with the different setting in Display Settings for the external monitor it suddenly starts working in Mirrored Mode. I believe what gets it working is the Left mode which I cancel then set to mirrored mode.
The lay out prior to mirrored mode is laptop on the Right external on the Left.

I have the xorg.config file
Comment 5 Bug Zapper 2009-11-18 06:10:30 EST
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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: 
Comment 6 Bug Zapper 2009-12-18 02:59:12 EST
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
