desktop sluggish after resume from suspend

[Pavel Rojtberg]

after resuming from suspend unity/ compiz feels like it renders much less frames per second. Moving windows around is very jerky as are the animations of the sidebar.
While moving around a window the Xorg CPU utilization spikes to 48%, so its eating up one of my 2 cores.

logging out and logging in again solves the problem. Switching to VTs however does not.

furthermore I got this on my kernel log:

[Pavel Rojtberg (rojtberg)]

kernel message was unrelated. Just checked with linux 3.1.0 from edgers ppa and there is no kernel message, but compiz is still sluggish.

[Mario (mariodopico)]

Also affect me, with 11.10 [64 bits] and radeon 5770.

This is a bug in Unity, because it does not happen in Gnome Shell.

How to play:

Go to Unity Dash, show all applications, move icons up and down with the scroll bar, suspend and resume, perform the same operation and notice that is very slow.

[Mario (mariodopico)]

Confirmed that the bug is in Unity

Alt-F2 --> unity --reset fixes the problem.

This bug should be passed to Unity instead of xorg?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Greg Michalec (greg-primate)]

FYI - this bug still persists in 12.10 beta. I've always assumed this was an issue between compiz and the radeon open source drivers. I have a Radeon HD 5470.

[Greg Michalec (greg-primate)]

Is this bug a duplicate of https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1004475? Or vice/versa?

[Jean-Pierre Rupp (xenog)]

I have a computer with an nVidia video card, using proprietary drivers. I experience this issue.

I have to add that after a suspend/resume cycle my videos playback slowly if they are enlarged, but normally when there's a 1:1 relation between display pixels and video pixels, meaning that hardware accelerated video resizing isn't working properly. I hope this information may be useful to diagnose this issue.

Reloading compiz fixes the issue.

[Eduardox123 (ebeduardox06-deactivatedaccount)]

This affects ubuntu 12.10

[Valentin (valentin-stn)]

This affects also Ubuntu 13.04, it could be the same bug as

- https://bugs.launchpad.net/ubuntu/+source/unity/+bug/892544
- https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/887993
- https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1004475
- https://bugs.launchpad.net/compiz/+bug/1113325

and maybe there are more of them. In the other Bugreports it seems, that the Gallium radeon driver has something to do with the problems.

[Valentin (valentin-stn)]

Added "compiz" to affected projects, because after "compiz --replace" the framerate is okay again.

[dirkd (dirk-dierickx)]

Same problem started for me after upgrade from 12.10 to 13.04 on a Acer Travelmate 7740 with Intel GPU.

Pavel Rojtberg, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspend ?

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
