Description of problem:
If I connect external monitor to a laptop and set active both display in clone mode (xrandr --auto), then external monitor behaves like a resolution is 1600x1200, but laptop display is damaged. Physical resolution is set properly 1680x1050, but display behaves like resolution is 1600x1200, so both panels in gnome has bad width (only 1600 instead 1680) and bottom panel is not visible, because is at position around 1200 instead 1050.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. connect external monitor
2. xrandr --auto
At external monitor is ok, but at laptop display has a problem. Physical resolution is set properly (1680x1050), but display behaves like the resolution is (1600x1200) which is resolution of external monitor.
Laptop display behaves like a resolution is 1680x1050 and external monitor behaves like a resolution is 1600x1200.
It does not matter, if I set external monitor by:
xranrd --output LVDS --mode 1680x1050 --output VGA --mode 1600x1200 --same-as LVDS
The situation is same.

Here are information that you requested.
Based on the date this bug was created, it appears to have been reported
during the development of Fedora 8. In order to refocus our efforts as
a project we are changing the version of this bug to '8'.
If this bug still exists in rawhide, please change the version back to
(If you're unable to change the bug's version, add a comment to the bug
and someone will change it for you.)
Thanks for your help and we apologize for the interruption.
The process we're following is outlined here:
We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. 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bug reports from releases that are no longer maintained.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 '8'.
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 8'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 8 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:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
