Red Hat Bugzilla – Bug 429870
Monitor signal ceases when machine left unattended
Last modified: 2009-10-22 08:44:12 EDT
Description of problem:
If I leave the machine unattended for a while (30+ minutes), when I get back the
monitor has switched off. Moving the mouse and pressing keys does nothing.
Switching the monitor back on does nothing. The machine's On light is on, but
the screen is blank.
Version-Release number of selected component (if applicable):
Every time if the break in time is long enough.
Steps to Reproduce:
1. Leave machine unattended for half an hour
Monitor is off, and when switched on it still doesn't get a signal and remains
blank. I can't close X Windows and Ctrl+Alt+Del is ignored.
I expect the monitor to switch on and get a signal once I press a key or move
I'm using a Gateway dual core desktop PC.
I've changed a line in my grub file to try to help, but to no avail:
kernel /vmlinuz-126.96.36.199-85.fc8 ro root=/dev/VolGroup00/LogVol00 rhgb quiet apm=off

This file is the one generated by Fedora---I haven't touched it
File supplied as requested. But note that I haven't changed it. Fedora 8
figured out the screen & graphics card itself. (Also, I'm now wondering if the
problem is due to the kernel's handling of powersaving---but I don't know.)

The other requested log file (I have no more)
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bug reports from releases that are no longer maintained.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.
