Description Ryan McGuire 2011-09-08 12:19:59 UTC

Description of problem:

I have a Lenovo T420 laptop that is connected to a port replicator. There is a LCD monitor connected to the VGA port on the replicator (this the main monitor). I have another LCD monitor connected to the DisplayPort port with a DVI adapter. The screens are set to go to sleep after five minutes. The screen go to sleep, but the monitor on the DisplayPort never wakes up. I have to go to the KDE Display and Adapter settings and disable the monitor; then re-enable the monitor to get it to work.

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

Fedora 15, KDE 4

How reproducible:

This happens every time my screen goes to sleep.
 
Steps to Reproduce:
1. In KDE, go to system settings.
2. Open Power Management.
3. Pick a profile and change "Screen Energy Saving" to whatever value.
4. Wait for monitors to go to sleep.
  
Actual results:

Once the screens go to sleep, the monitor connected to the DisplayPort using the DVI adapter will not wake up.

Expected results:

Both monitors will wake up.

Comment 1 Fedora End Of Life 2012-08-07 19:02:55 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Fedora's policy to close all bug reports from releases that are no
longer maintained.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:
