Description of problem: After I suspend my laptop and resume I find that gnome-shell is using 30-60% of my CPU. I have to <F2>r restart the shell to get the CPU usage back down to the usual 1%. Version-Release number of selected component (if applicable): gnome-shell-3.2.1-1.fc16.x86_64 How reproducible: everytime Steps to Reproduce: 1. suspend the computer 2. resume the computer 3. use htop to see the gnome-shell usage Actual results: Expected results: Additional info:
I have exactly the same issue on my IBM T61 laptop. But it seems to be the same thing after a yum update/installation of packages.
Similar result on a T520, but it doesn't seem to need a suspend/resume. Not sure yet whether screen blanking or just waiting long enough does it. gnome-shell 3.2.1-2 kernel 3.1.0-5
I agree with the observation that it doesn't require suspend/resume. It seems to be a screen blank or idle to long problem.
Last night I rebooted shortly before bed, did a quick check and then left it. gnome-shell was consuming 85% CPU in the morning, memory about a half gig. I think this may be related to the memory bug.
I'm thinking this is probably a blocker, and also suspect it is the same as 726978. The system gets pretty miserable after a while with a bunch of cores, with only one I suspect it would be unusable. The Alt+F2-r thing works well, but not the sort of thing you want to ship. I'm marking as a blocker so it at least gets discussed.
Discussed at the 2011-11-02 go/no-go meeting, agreed this is rejected as a blocker: it's hardware specific (i.e. does not affect other hardware, as attested at the meeting), doesn't infringe any criteria, and can be reasonably addressed with an update. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Are you sure that's hardware specific ? Because we seem to have 3 different hardware and the same issue. I'll try on another computer, to see if this issue still exists..
Yes. I have two systems running F16 full time and have not seen this once on either of them; two other people in the review meeting said the same thing about their hardware. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Last night some folks seemed confident that it had to do with the graphics. Not sure what evidence there is of that, but for reference, mine is a i7-2760QM with Nvidia NVS 4200M.
I use an Intel graphics card i915 (sandybridge). I'm curious, what hardware is this bug specific to? Not the graphics card apparently.
could be configuration specific too - point is, it doesn't affect all systems. are you all using any Shell extensions? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Yes, I am using shell extensions. After some experimentation, my CPU problem goes away if I disable SystemMonitor. And that makes me remember, that I always wondered why my CPU under htop was 60% while SystemMonitor never showed a problem. Of course, many gnome-shell-extension-* packages are broken.
I believe there was an ML thread where someone mentioned System Monitor was causing issues, too. Are you rest of you using that extension as well? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
You're totally right, I'm also using this extension.
Same here
Updating summary and re-assigning. Upstream has one recent commit to system-monitor: http://git.gnome.org/browse/gnome-shell-extensions/commit/?id=2bba98d6214cffae2eb5cecb9d7c1f6b6d244052 I dunno if that'd help this. There doesn't seem to be an upstream report of this specific issue. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
That just fixes it so that disabling/enabling the extension works correctly. The way it works is that we retrieve values from GTop and re-draw the entire monitor every half second, even if the actor is not being displayed. That is quite resource intensive. Please file a new bug.

I have the same problem as the original reporter on a HP 8540p laptop since I have installed and turned on SystemMonitor. x86_64, all updates installed, + latest binary nvidia drivers from rpmfusion.
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
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.
