Description Bartholomaeus Dedersen 2011-07-05 10:44:03 UTC

Description of problem:

I installed powertop to reduce power consumption and let my laptop go
into standby mode. After waking up the password input dialogue of GDM 
reacts very slowly to each keyboard input. After login the delay is still 
there(about one second per key press).

The temporary bugfix is opening a console window and running powertop. After
it starts the keyboard reacts normally as usual.

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

PowerTOP 1.98 beta 1

Steps to Reproduce:
1. Install powertop
2. Run powertop as root from console(no need to change settings)
3. Close powertop
4. Go into standby
5. Wake computer up
6. Suffer from big delay on input
  
Actual results:

Keyboard input slowed down. About 1 second delay per key press.

Expected results:

No slowdown.

Comment 1 Bartholomaeus Dedersen 2011-07-06 12:30:11 UTC

I observed additional behavior which might lead to the fix:

If I do not use powertop after the slowdown and immediately go again into
stand-by the error ceases.
After I wake it up everything works again without running powertop again.

Comment 2 Fedora End Of Life 2012-08-07 16:40:46 UTC

This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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:
