Description Jan "Yenya" Kasprzak 2010-11-20 22:51:53 UTC
Description of problem:
I have installed a fresh F14 installation from DVD+network to a HP 6730b laptop. Then I have tried to log in. The performance was very sluggish, and the display was redrawn very often, resulting in blinks every second or two. I have compared the running processes to my other system (F14 upgraded from F12), and found that the laptop has several instances of /usr/bin/gcm-apply process running. After removing gnome-color-manager package via rpm -e, the display stopped blinking and the performance became normal.

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


How reproducible:
100 % (I have tried to install F14 twice - once from DVD and later yum update, the second time using DVD+network to get an up-to-date system)

Steps to Reproduce:
1. Install fresh F14 on HP 6730b
2. Log in as user
  
Actual results:
blinking display (even during gdm prompt), sloooow response to keyboard input.

Expected results:
steady display, acceptable response time.

Comment 1 Richard Hughes 2010-11-22 08:43:19 UTC
If you run "/usr/bin/gcm-apply --verbose" what is printed out? Thanks.

Comment 2 Andy Lawrence 2011-01-09 17:50:13 UTC
Had the same problem on a Dell E5500, F14 all updates as of yesterday.  F13 did not have this issue.  Removing gnome-color-manager fixed the issue.

Comment 3 Richard Hughes 2011-11-15 12:28:50 UTC
Does this still happen in F15 or F16?

Comment 4 Jan "Yenya" Kasprzak 2011-11-16 12:24:11 UTC
I cannot reproduce it under F15, so you can probably close this bug after F14 EOL.

Comment 5 Fedora End Of Life 2012-08-16 22:15:33 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. 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Fedora's policy to close all bug reports from releases that are no 
longer maintained.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 '14' 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 14 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:
