[Bug 1102318] Re: Slow system after resume from suspend
Roman Dinga, 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 in the development release
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>
Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc4
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
If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER
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:
Slow system after resume from suspend
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Hello,
For quite some time I've been experiencing problems with Ubuntu after
resume from suspend. I have an Asus M70SR notebook with ATI Radeon
Mobility HD3470 and using the open-source driver for it (from Quantal
official repository). Currently I have Ubuntu 12.10 installed, but the
same was happening before with 12.04. It doesn't matter if I use
Unity, Gnome-Shell or Gnome Classic - the slow down is always there.
My /etc/X11/xorg-conf looks like this:
Section "Device"
Identifier "ATI Radeon 3470HD"
Driver "ati"
Option "AccelMethod" "EXA"
Option "AccelDFS" "true"
Option "EnablePageFlip" "true"
Option "SwapbuffersWait" "off"
Option "ColorTiling" "on"
Option "ColorTiling2D" "on"
EndSection
To give you some picture about it:
Glxgears BEFORE suspend:
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: option value of option vblank_mode ignored.
4007 frames in 5.0 seconds = 801.315 FPS
3867 frames in 5.0 seconds = 773.359 FPS
3918 frames in 5.0 seconds = 782.475 FPS
3879 frames in 5.0 seconds = 774.902 FPS
3859 frames in 5.0 seconds = 771.025 FPS
Glxgears AFTER resume from suspend:
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: option value of option vblank_mode ignored.
519 frames in 5.0 seconds = 103.466 FPS
455 frames in 5.0 seconds = 90.993 FPS
449 frames in 5.0 seconds = 89.738 FPS
553 frames in 5.0 seconds = 110.366 FPS
530 frames in 5.0 seconds = 105.835 FPS
As you can see the performance after resume from suspend is about
1/8th of the normal. The workaround is to kill the X server (Ctrl-Alt-
Backspace) and login again, the problem is gone then. However, it's
quite annoying to have to close all open apps and then reopen them
again.
As you can see, I use vblank_mode=0 option and in Compiz the Vsync is
turned off. The measuring was done from Gnome Classic session, but I
can experience the same slowdown in Unity and in Gnome Shell as well.
Best regards,
Roman Dinga
