Description of problem:
After installing, system-config-display allows me to select screen resolutions
of 640x480 and 800x600 only. Manually editing the xorg.conf file and setting the
required resolution to 1440x900, I get a "desktop-in-desktop" effect. That is to
say that whole desktop displays at 1440x900 but I will have another 800x600
"desktop" in the upper left hand corner of the screen. Any application that is
within that 800x600 space will be maximized to that 800x600 "desktop" space,
while applications that are outside can be maximized to full screen. Attached is
a picture of yumex and the 2 gnome panels being constrained within the 800x600
"desktop" while xchat is maximized to 1440x900.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run system-config-display
2. Manually edit /etc/X11/xorg.conf file
3. Restart X
800x600 maximum resolution selectable. Manual editing of xorg.conf file results
in a "desktop-in-desktop" effect where a 800x600 "desktop" exists inside a
system-config-display should give me the option of selecting 1440x900. Desktop
should display at 1440x900 without the additional "virtual desktop" in it.

Alright! That seems to have nailed down the problem. Thanks!
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bug reports from releases that are no longer maintained.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.
