[Upstream] LibreOffice repeatedly freezes after resuming laptop from sleep

[Louis-Dominique Dubeau]

Binary package hint: openoffice.org

I've used Feisty and Gutsy but this problem has started happening only recently. Here are the steps to reproduce:

1. Open a document in oowriter.

2. Put the laptop to sleep.

3. Resume the laptop.

Here are the symptoms:

1. Scrolling in the openoffice document is jerky. Basically, if I hit page up or page down, oowriter freezes for a few seconds and compiz grays the oowriter window (to show that the app is not responding), eventually oowriter unfreezes, refreshes its screen and is responsive again. If I try to scroll again, the same freeze repeats.

2. Sometimes oowriter seems to also cause other applications to temporarily be unresponsive. The symptom here is that compiz grays *all* the windows on the screen for a few seconds until oowriter becomes reponsive again.

3. No other application freezes like that after resume. Note that symptom 2 above happens *only* when oowriter is running.

WORKAROUND: Restart OOo/LO.

WORKAROUND: Turn off compiz.

+ Possibly related to bug 745836.

Why has this bug been marked invalid?

[Chris Cheney (ccheney)]

Louis-Dominique,

I'm sorry I am not sure why I marked the bug as invalid, I think I must have clicked the wrong thing by accident.

To respond to the bug:

Can you reproduce this bug if you have compiz disabled?

I can't reproduce this bug myself but that is primarily due to the fact I can't easily suspend/resume my laptop to begin with.

Thanks,

Chris

[Louis-Dominique Dubeau (ldd)]

Thanks for the reply. I've tried quickly to reproduce it after turning off compiz but the bug did not come back.

I will keep compiz turned off on my machine for a few days and see whether during my normal day to day use the bug comes back again because it might be a combination of various factors that make it manifest itself. I've set myself a TODO item for Friday the 22nd. If I get the bug again before then, I'll report right away. If not, I'll report on Friday that the bug is irreproducible with compiz turned off.

[Louis-Dominique Dubeau (ldd)]

At this point, I'm going to say that turning off compiz makes the bug disappear. I've used Open Office intensively yesterday and today and put my laptop to sleep several times without the bug recurring.

I'm still perplexed by the fact that when compiz is running the bug appears *only* when Open Office is also running. No other software shows this behavior. I run evolution and Firefox for long stretches of time and they go through all the same sleep/resume cycles as Open Office and yet no problem with them.

What now? Make this a compiz bug?

[Chris Cheney (ccheney)]

I have reassigned this bug to compiz. I am not sure why it only happens to openoffice but compiz has made lots of weird bugs pop up in the past so I am not surprised in seeing it be attributed to compiz. It may end up actually being a bug in openoffice of some sort that only is triggered when compiz is enabled.

I can report this same problem on wake up with open office and compiz. Problem happens consistently and is replicable.
Openoffice 1.2.4

NVIDIA driver 169.12

Basically, after wake up from suspend, when I hit scroll page up or page down, I can watch my CPU usage kick up to 100% and freeze everything up. I have a 2.0 GHZ Dual Core Pentium with 4 GB RAM, Dell XPS 1330.

I've attached my /etc/default/acpi-support file, if that is helpful.

Also, I've installed Open Office 3.0 from the Open Office web site to try it out. I know this is not an official Ubuntu package but for what it's worth: the problem happens with it too.

[Harm van Bakel (hvbakel)]

I can confirm that this problem still occurs in Ubuntu 9.04 (Jaunty)

[Caleb (caleb-marcus)]

Considering this is a bug that occurs extensively, during very typical laptop usage patterns, with 100% default preinstalled applications, it would be nice to see it getting more attention... having to restart OpenOffice each time I resume the system is inconvenient.

Anyone who uses suspend and resume on a laptop (quite common) capable of 3D acceleration so Compiz is enabled automatically (almost ubiquitous now) who uses word processing (who doesn't?) is affected by this rather crippling bug... I can't see editing documents while on the go as a very specialist or rare use case.

I should mention that I have not tested this with OpenOffice.org 3, on Jaunty.

[Robert Ancell (robert-ancell)]

Thanks for your bug report. The symptoms provided indicate this is a problem with your video drivers and is being reassigned to the xorg package. For more information on problems with visual effects and video drivers see http://wiki.ubuntu.com/VisualEffects.

[Bryce Harrington (bryce)]

I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get nvidia-graphics-drivers-180 - 185.18.14 here:

  https://edge.launchpad.net/~xorg-edgers/+archive/ppa

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

[Louis-Dominique Dubeau (ldd)]

I've installed 185.18.14 from the PPA as requested.

The bug is still present.

Here's the version on nvidia-180-kernel-source:

$ dpkg-query -W nvidia-180-kernel-source
nvidia-180-kernel-source 185.18.14-0ubuntu1~xup~1~jaunty

[Austin Dempewolff (adempewolff)]

This bug also affects me.

Ubuntu 9.04
2.6.28-15-generic
nvidia-180-kernel-source 180.44-0ubuntu1
openoffice.org-core 1:3.0.1-9ubuntu3

When I hibernate with openoffice.org writer and then resume, scrolling in writer will send xorg's cpu usage up to 100%

Restarting openoffice.org fixes the problem.

[geoffrey (gkgeko)]

Hi, just realised that I had filed a report for the same bug, #397880, I marked mine as duplicate.

Just a couple of details that have not been mentioned here: it is actually not necessary to restart OOo to solve the problem: it is enough to close individual files and open them again to get them to work. Also, any file opened after resume will work fine, even if other files that had been opened before suspend are still presenting the problem.

I am on Jaunty 64bit, nvidia Quadro NVS 135M driver version 180.44.

[geoffrey (gkgeko)]

I just realised that *unmodified* OOo documents work perfectly after resume. So if I open a document and don't touch it until suspend, it will not cause the problem described. If I open a document, modify it, then suspend, I get the problem - it makes no difference if I save the document first or not.
(btw, I am now on Karmic)

Hope this helps in identifying the problem.

[geoffrey (gkgeko)]

edit: if I have two documents - one unmodified, and one modified - opened at the same time, then only the second will present the bug.

[Austin Dempewolff (adempewolff)]

I don't know if this is related at all--but I haven't noticed this bug ever
since I fixed this related bug:
http://ubuntuforums.org/showthread.php?t=1237608. I haven't spent
significant amounts of time testing it, and can't say that wasn't something
else that fixed it--but if you use compiz and have an nvidia card it would
definitely be worth trying. Good luck.

[geoffrey (gkgeko)]

Thanks adempewolff - however in my case the 'Force synchronization between X and GLX' option in Compiz was already checked, I tried unchecking it but nothing has changed.

[Mark Baas (mark-baas123)]

I have nvidia driver 195 and still have this bug. However restarting compiz is also a solution. Therefore, i developed a pm-utils hook that restarts compiz (and gnome-panel) after resuming from suspend or hibernate only in case openoffice is running.

Copy the attached file to /etc/pm/sleep.d and make it executable (chmod 755 /etc/pm/sleep.d/0000restart-compiz).

[geoffrey (gkgeko)]

@Mark Baas: This is great, thank you so much! I installed the script yesterday, and so far has been working perfectly.

[Louis-Dominique Dubeau (ldd)]

This problem is present on Ubuntu 10.04 (Lucid).

"Force synchronization between X and GLX" has no effect here.

[Gorka Navarrete (emrys)]

As said in a duplicate of this bug, the problem persists in 10.10 (64-bits), using Openoffice or Libreoffice, with the last 260.19.06 Nvidia drivers.

[eva dany (unsichtbarkeit)]

i can confirm this bug on my machine.
i have macbook pro, and running a fresh installed ubuntu 10.10
after resume from suspend/hibernate openoffice is very slow with typing and scrolling.
killing openoffice will help.

[Louis-Dominique Dubeau (ldd)]

Ok, so this is happening again in 10.10. I've noticed a few more things though:

1. This bug sometimes causes X to crash. I've experienced it a few minutes ago. I had resumed from suspend maybe 4 hours ago and worked on a bunch of things in Emacs, Firefox and Evolution and a few other X clients (like xpdf). Then I turned to Open Office writer to check something in a document. The document was very slow to scroll. Writer was in effect exhibiting the symptoms described earlier in this bug report.

After paging up maybe 4 or 5 times, X crashed.

The only X client started before the suspend-resume cycle and which showed any trouble was Open Office. (Emacs, FF, Evolution were also all started before the suspend-resume cycle: no problem with them.)

2. The soffice.bin process remained running from the previous X session. Note that everything else which was X related died when the X session died. Only, soffice.bin remained. Running oowriter from the command line does nothing. The old soffice.bin must be killed before OO can be used again.

3. I checked to see whether the HD was being accessed abnormally (e.g. thrashing) but did not see anything abnormal there.

Why did I not experience X crashes before? I think the answer is just that in the past, I would very quickly close OO as soon as I experienced the bug so I was removing the opportunity for a crash. This time, I insisted on scrolling to a bit of text I needed to cut and paste to emacs. I thought I was really close to the passage I wanted to cut and paste but I was wrong and X crashed before I could get there.

It may also have to do with the document I was scrolling. This is the largest OO document I have. It also happens to contain about as much Chinese as English. So of all the documents I work with this is the one which is most taxing on oowriter.

Here are the results of apt-cache policy on the usual suspects:

[Berezin Kirill (pechenie-k)]

I can also confirm this bug under Ubuntu 10.10 and absolutely-all-fresh-updates-installed.
I also have nvidia card and proprietary drivers installed. Sounds like it is vendor-specific (nvidia) compiz problem.

I expirience this bug from 9.10, as I can remember. Reopening OO.org Writer hepls, but it is very uncomfortable to answer "Yes or no" to the response of saving changes when I can't remember what are they in such situation.

This bug is 2 years old, so sad there is still no solution.

[Austin Dempewolff (adempewolff)]

I switched over to Fedora for awhile then went back to Ubuntu ~6 months ago and this problem has popped back up again (currently still using 10.04). Very frustrating, because as my post from 2 years ago suggests, I somehow fixed the problem on that old install. Now however, I cannot figure out how I fixed it. Force sync between X and glx isn't doing it, so it must have been something else I did back then inadvertantly.

It looks like it is just a bug for people who have Nvidia cards. If other subscribers want to try and get this bug off the ground I am game to participate in some more troubleshooting and group brainstorming.

I have noticed that not all windows lock up, and the suggestion above that only modified documents lock up sounds like a very likely explanation. I remember seeing a bug somewhere about openoffice locking up after a resume when it tries an autosave, maybe this is a related bug. Doesn't make sense why whether the document is modified or unmodified would matter if the problem is with compiz... very strange.

Well for now I am going to try the restart compiz on resume script as a workaround. I agree that this is a really silly bug to be unsolved after 2 years, especially when I could have sworn I fixed the problem once upon a time!

[Austin Dempewolff (adempewolff)]

Another thing that might be worth noting after reading Louis-Dominique Dubeau's comment is that I have also noticed that the bug is more serious in documents with Chinese text. I've been translating texts recently, so I will have documents in both languages open simultaneously, and after a resume I sometimes won't notice the bug at first when I start using the English document, but the second I try scrolling on the Chinese document the bug is very apparent!

[Gorka Navarrete (emrys)]

The problem persists with a clean Natty installation. This is a serious and very frustrating bug. Particularly the fact that there seems not to be any progress here. Any idea about where this should be reported to make it more visible?

[Gorka Navarrete (emrys)]

After waking up from suspend having a LibreOffice document opened, Libreoffice becomes unusable, freezing, etc. There is a long and old, but still prevalent, description of the problem in Launchpad. The problems it's been with us more than 2 years now.

https://bugs.launchpad.net/compiz/+bug/185600

This happens at least in Ubuntu 64-bits and seems somehow related to compiz.

[aldebx (aldebx)]

- NVIDIA propietary 270.41.06-0ubuntu1
- Compiz 1:0.9.4+bzr20110415-0ubuntu2

after resume from suspend or switching user libreoffice is so slow that is unusable and almost makes the computer freeze.

[aldebx (aldebx)]

I just want to add that I'm not using Unity, instead I'm using the standard GNOME interface, still I experience this bug.

[Gautham Pai (buzypi)]

Same here. I am on Ubuntu 10.04 and experience this issue.

$ uname -a
Linux ananya 2.6.32-32-generic-pae #62-Ubuntu SMP Wed Apr 20 22:10:33 UTC 2011 i686 GNU/Linux
$ cat /etc/issue
Ubuntu 10.04.2 LTS \n \l
$

[Gorka Navarrete (emrys)]

Gautham, do you have an NVIDIA graphic card?

The problem seems arise from an interaction between NVIDIA, Compiz and Libreoffice...

[Gautham Pai (buzypi)]

Yes I do.

I just wanted to mention that this is not just in Unity based environments but it is present in Ubuntu 10.04.

[Mahendra Tallur (mahen)]

Indeed, it's happened for several Ubuntu releases already : only when Compiz is enabled (and thus, Unity as well as it's a Compiz plugin), and apparently only with Nvidia cards (proprietary driver).

[Philippe (philippepiatkiewitz)]

Can confirm this bug on Ubuntu 11.04
NVidia driver 270.41.19
Compiz 1:0.9.4+bzr20110606-0ubuntu1~natty2
Libreoffice: 1:3.3.2-1ubuntu5

I did not have this behavior prior to upgrading from 10.10 to 11.04. I am not sure when exactly it started to occur. Maybe it has to do with the NVidia drivers that I installed from NVIDIA directly?

[Sebastian Rühl (sebastian-ruehl)]

Upgraded a Samsung R510 from 10.10 to 11.04. Now Open Office shows the described behavior (corrupted screen and really bad responsiveness). To note that this Laptop uses a Nvidia 9200M GS. However this Problem is independent of the system state (sleep and resume) and occurs all the time. So as I understand the only workaround is to switch to ubuntu classic (without effects) because of the dist-upgrade?

[Phil Colbourn (philcolbourn)]

Similar prob. MacBook Pro 4,1
With binary nvidia driver

Linux max 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Happens when LibreOffice is running and laptop sleeps/resumes.

Typically Writer is very slow and causes whole laptop to pause for several seconds.

Get this error in Xorg.0.log:
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

To 'fix' I rmmod bcm5974 and modprobe bcm5974 and quickly kill LibreOffice and reopen it.

The trackpad (BCM5974) clicks still function but there is no mouse cursor.

I have bcm5974 removed/reinstalled before/after a sleep/resume - does not seem to help.

No other application seems to cause this.

Need anything else?

PS: A friend with a virtually identical setup has same problem.

[Phil Colbourn (philcolbourn)]

Also, 1 CPU is fully utilized as I attempt to scroll.

[Phil Colbourn (philcolbourn)]

An odd thing that we have noticed: if you run draw, and go through a sleep/resume cycle, this problem goes away. Then you can close draw and your calc and writer will be stable through multiple sleep/resume cycles.

It may be too early to post this observation, but in my hope that it offers a valuable key I thought it worth mentioning.

Another possibility is that it is July 7 - but I doubt it somehow ;)

[Björn Michaelsen (bjoern-michaelsen)]

Possibly related to bug 745836.

[Phil Colbourn (philcolbourn)]

This lasted one day. I don't understand this fault. It is not perfectly repeatable and, as I found, it can disappear for a whole day and then reappear which makes it hard to nail-down and confirm what causes it.

[JKL (jkl102001)]

I am also running the nvidia drivers, and due to this problem, I switched to metacity. Initially I thought the problem had gone away, but on the most recent resume it reappeared. Not only that, I discovered several additional issues I hadn't noticed before.

* if writer is on a different workspace and not minimzed, it takes several seconds for the writer window to repaint when switching to its workspace. During that time, the mouse cursor is moveable, but the desktop does not respond to mouse clicks, and the system monitor graphs freeze. Other windows are not repainted either (e.g. a terminal running 'top' isn't updated).

* If the writer window is minimzed, there is no problem switching workspaces.

* restoring the writer window after minimizing it takes several seconds, and during that time the desktop is freezes as when switching workspaces.

* When the system is frozen during the writer repaint, the Xorg process fully loads one CPU core. But that is the only process that uses excessive CPU time. In particular, neither the writer process nor metacity create additional load.

[JKL (jkl102001)]

Here are some interesting entries from my X log. According to the below page, a likely root cause is GPU lockup.

Just thought I'd post that I cannot find a good workaround. I did find a *bad* workaround, which is to let the power management daemon just kill off soffice.

The reason this is better than the current bug is that the current bug has the potential to completely hang the system if you fail to kill soffice quickly. It's horrible, but I haven't found anything else that works. (One poster in the original launchpad bug suggested using compiz -replace in a pm.d script, but that did not work for me.)

Bad workaround
--------------
Create a file:
    sudo touch /etc/pm.d/sleep.d/20_kill_soffice
    sudo chmod +x /etc/pm.d/sleep.d/20_kill_soffice

Add these contents:

#!/bin/bash

PATH=/sbin:/usr/sbin:/bin:/usr/bin

SELF=kill-soffice
COMMAND=

# pm-action(8) - <action> <suspend method>
#
# On suspend|hibernate, kill soffice due to compiz-related hang:

This happens to me on libreoffice 3.4.4. with Gnome Shell and mutter as well, when compiz is not runnig. I use the nvidia drivers.
I still wonder who is the culprit: libreoffice, the compositor (mutter/compiz), or the driver (nvidia)?

Still having the problem in LibreOffice 3.5.1.2 Build ID: 350m1(Build:102) with Ubuntu 11.10.

If the system is powerful enough (8 cores, 16Gb RAM, SSD disk, etc.) it is annoying but not critical. With an inferior system, the computer becomes unusable and the only way forward is closing all LO instances.

There is anything I can o to help triage this?

[Gorka Navarrete (emrys)]

I think I might have made a mistake and attributed an improvement in the situation to LO instead of to a faster computer. It is true that libreoffice does not render the system unusable after waking up from suspend but the problem somehow persists.

With a modern computer what you would notice now is a CLEAR slowing in LO (e.g. when scrolling down the page LO is very slow and unresponsive).

You still have to completely close LO and reopen it again for it to work properly.

There has been 33 people confirming the bug since 2008 (in the Ubuntu bug report). The problem persists with LibO 4.3.2.2 (430m0(Build:2)) in Ubuntu 14.10 64bit.

To replicate, open a writer document with a few pages, suspend, wake up, scroll down.

Scrolling down is painfully slow, the LO screen grayes out and becomes completely unresponsive, along with the whole computer.

[penalvch (penalvch)]

napel, this report is closed as the original reporter hasn't responded in 6+ years, it is likely a hardware dependent issue, this report is bogged down with a tremendous amount of unhelpful "Me too!" comments, and so little debugging information was provided it is largely impossible to root cause.

If you would like your issue addressed, it will help immensely if you use the computer the problem is reproducible with, file a new report with Ubuntu by first ensuring the package xdiagnose is installed, click the Yes button for attaching additional debugging information after running the following from a terminal:
ubuntu-bug xorg
