Description Milos Jakubicek 2008-05-13 08:28:59 EDT
Description of problem:

When connecting an external monitor to my laptop (in order to use the "clone"
mode), I'm unable to set proper resolution on it (1680x1050) -- it starts with
1024x768. This has worked in F8 (see my xorg.conf_f8). I managed to tweak the
xorg.conf a bit, so that I have at least 1200x960 (see xorg.conf_f9, Xorg.0.log)
-- am I doing something wrong?

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


How reproducible:


Steps to Reproduce:
1. connect the external monitor
2. boot up
Actual results:

It starts with 1024x768 (with xorg.conf_f8) or 1200x960 (with xorg.conf_f9) on
the external monitor.

Expected results:

It should start with 1680x1050 on the external monitor, as does F8 (with

Could you try to set up your dual head with gnome-display-properties (from the
control-center package)? If it doesn't work for you, could you to restart x
without any /etc/X11/xorg.conf and try again, please?

Thanks for filing the  bug
Comment 5 Milos Jakubicek 2008-05-15 04:16:58 EDT
1) gnome-display-properties: When checking the "mirroring" box, I can choose
only 1024x768 for both displays from the combobox. Otherwise I can choose proper
resolutions for both displays. But in both cases clicking on "Apply" doesn't
seem to take any effect (neither the dialog closes, nor anything is written into

2) Starting without xorg.conf results in having 1024x768.

Thanks in advance!
Comment 6 Milos Jakubicek 2008-05-29 13:14:41 EDT
As a workaround, after login I can set proper resolution by:

"xrandr --size 1680x1050"

However, I can't use the --output parameter to set this resolution only on the
external monitor (when trying --output LVDS/VGA --size 1680x1050 it doesn't have
any effect).

As a side-effect, when using "xrandr --size 1680x1050", the laptop monitor goes
Comment 7 Bug Zapper 2009-06-09 20:45:30 EDT
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  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bug reports from releases that are no longer maintained.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 '9'.

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 9'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 9 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 8 Bug Zapper 2009-07-14 13:40:22 EDT
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
