screen looking strange
Description of problem:
When you don't use your computer the display will turn black in order to save some power. On the XO laptop after 20(or so) minutes of being pure black the display color changes to grey (sort of) and a square spot appears on the screen. The screen appearance (excluding the spot) is similar to when one starts X without any desktop environment or window manager.
Version-Release number of selected component (if applicable):
Fedora 10 Preview release
Always on my XO
Steps to Reproduce:
1. Boot and login to the desktop
2. Leave the computer idle for 20-30 minutes
See screen shots
I'm not sure what's causing this and it might be related to the video driver or the missing power management capabilities for the XO.

pure black screen
this is when you either lock the screen from the desktop menu or when it turns black after the system is booted. The spots on this one are just reflections from the light in the room.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

Xorg.0.log when running with the attached xorg.conf

Xorg.0.log when no xorg.conf
Steps to reproduce:
1) init 3
2) rm /etc/X11/xorg.conf && rm /var/log/Xorg.0.log
3) init 5
The screen goes ugly right after X starts. It goes through several phases which are clearly wisible and finally (in a minute or so) the strange rectangular shape appears (see screenshots). GDM menu never shows.
I'm thinking that this may be an artifact of how the display is designed. At that point it would probably be trying to power down the display, and it may be that it's doing it incorrectly. We should bring in a OLPC engineer on this.
In my case it's definitely a power down issue; it can be replicated by running "gnome-screensaver-command -a ; xset dpms force standby".
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
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:
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.
