Mario, 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.

Title:
  Unity slow after resume from suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After resuming from suspend unity feels like it is very slow.

  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.

  This already happens with the (cd or usb) of installation.

  This bug only happens with free radeon driver with driver fglrx does
  not happen.

  This only happens in unity, this does not happen in either Gnome Shell
  or Unity 2D.

  I do not know if it's a bug in Unity or compiz, but "unity --reset"
  solves the problem until the next suspend / resume.

  I do not know if this bug may be related to #782810 or #803943, but I
  did not notice any increase in CPU consumption.

  This bug occurs on a clean install of 11.10 [64 bits]   with a ATI
  Radeon 5770 graphics card,  Asus P6T Deluxe V2 Motherboard, Micro
  Intel Core™ i7-950 y SSD OCZ Vertex2.
