Description Klaas Vantournhout 2012-02-23 12:51:22 UTC
Description of problem:
When my computer is inactive for 50s, the screen turns blank.
I have no screensaver active at all and the system is not set 'performance', so the screen should not turn off.

I noticed that this is the result of the energy-star power management which turns off the screen after 50s. (output of xset q)

DPMS (Energy Star):
  Standby: 50    Suspend: 75    Off: 100
  DPMS is Enabled
  Monitor is On

This is weird as I placed in xorg.conf the following lines

Section "ServerFlags"
        Option "blank time" "0"
        Option "standby time" "0"
        Option "suspend time" "0"
        Option "off time" "0"
        Option "dpms" "false"
EndSection

Hence, dpms should be disabled, however it is not.

How reproducible:
always

Steps to Reproduce:
1.log into kde
2.wait
3.
  
Actual results:
The screen turns blank after 50s

Expected results:
I would expect this result under powersave mode. In performance mode, I expect that these numbers should be much higher (10min or so) or turned off.

Furthermore, xorg.conf states that dpms is turned off, however it is not. I would also expect it to be turned off.

Additional info:
A workaround I found was typing xset -dpms

Comment 1 Dave Airlie 2012-02-23 12:59:09 UTC
does it happen if you don't log in to KDE? my guess is KDE is setting this up and overriding the conf file.

Comment 2 Kevin Kofler 2012-03-23 19:29:11 UTC
The KDE (PowerDevil) settings can be customized in KDE System Settings.

Comment 3 Klaas Vantournhout 2012-03-23 21:31:28 UTC
It is true that most settings can be done with KDE System settings, however they do not affect this. There is no reference to 50 s in there.

When I do xset -dpms, dpms never turns on anymore, even after reboot. Only a certain kde update turns the dpms back on. I believe it is xsettings-kde, but I cannot confirm this 100%.

upstream bug https://bugs.kde.org/show_bug.cgi?id=295164 seem related

Comment 5 Fedora End Of Life 2013-01-16 19:45:43 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. 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bug reports from releases that are no longer maintained.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 '16'.

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 16'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 16 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, you are encouraged to click on 
"Clone This Bug" 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 6 Fedora End Of Life 2013-02-13 23:27:23 UTC
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 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.
