Was happening to me too.

For me it's not %10-20 of the time, it's more like after about an hour of normal use then for a period of 5 minutes then it goes away until it comes back in another hour. I was thinking it might have been the differences in processor power, but I'm on a i7 920.

The CPU usage is 'weird' when it happens. According to htop the different processors get random highish (%50-80) cpu usage but it doesn't max any of them out and no process in the list is listed as using much (other than Xorg which is around %20).

Also after it happens, when I try to playback using totem is throws up 5 error boxes about being 'disconnected' but then works fine if I quit and reopen it. I'll try and grab the actual error if it happens again. I'm thinking it might be pulse-audio or gstreamer related although maybe some media backend crashing is just a symptom of the problem.

I have since reinstalled, not sure if this fixed it or not. Seems it might have improved it somewhat though.

Something really should be done on this problem. It is a SERIOUS issue because it affects Ubuntu's credibility. Imagine what happens when someone finally tries the switch to Ubuntu and isn't able to play an audio file... plus a lot of people are affected

Affects me too. Dell Inspiron. Audio will often stutter but shaking the mouse will stop the stutter.

Have also noticed that the keypress repeat is affected. An example of this can be replicated when scrolling through text in a text editor; hold down a key to scroll ('j' in my case with VIM) and if the music is stuttering in the background so is my ability to hold a key down to scroll. Shaking the mouse re-enables smooth scrolling.

It might be helpful if we could track down what hardware is common to those of us that have the issue. I am running:

Foxconn Renaissance MB w/integrated audio (Intel Corporation 82801JI), Intel i7 940, NVIDIA 9500GT

I think this is probably a bug with the Intel Audio. The original poster had that too. There have also been other problems with it in the past.

00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller (listed as Realtek ALC888 in alsamixer)

Gigabyte EX58-UD3R, i7 920

This would probably make it a pulse-audio bug.

This bug is also affecting me. I am experiencing it on my Toshiba NB305 netbook. VERY annoying, to say the least. As others have mentioned, I was not experiencing this on 10.04. Interestingly enough, this happens during startup also.

I tried installing Fedora 13, and the same problem appears, only less often. I suppose it can help to know this is not due to Ubuntu or even Debian...

Changing /etc/pulse/default.pa:
load-module module-udev-detect
to
load-module module-udev-detect tsched=0
as per http://ubuntuforums.org/showpost.php?p=9958050&postcount=4 seems to have fixed it for me.

Obviously we are dealing with (at least two) different bugs here that cause similiar effects.

The bug that can be expelled with "module-udev-detect tsched=0" probably belongs to pulseaudio rather than to xorg
(BTW: Any hints what's going on here, why does that workaround fix the problem?)

While this was the most annoying bug for me, I sometimes still notice that the display freezes for some seconds when I try to move the pointer.

Actually the tsched=0 option didn't fix it %100 for me, but it doesn't happen around every hour anymore.

It's more like after 6 or so hours so it's not really a major issue.

I'm guessing how problematic it is, might be different depending on the power of the system.

According to: http://www.pulseaudio.org/wiki/Modules
"tsched: Use system-timer based model (aka glitch-free). Defaults to 1 (enabled). If your hardware does not return accurate timing information (e.g. Creative sound cards) you can try to set tsched=0 to enable the interupt based timing which was used in 0.9.10 and before."

Not sure why Xorg would be effected. Possibly they are using the same hardware timer since it's onboard and whatever pulse is doing breaks it occasionally? Otherwise maybe the CPU is being raped by Pulse Audio dealing with an out of control timer or a bug in the scheduling code, and Xorg is slowing down as a result. It doesn't report %100 of my CPU being used but it does seem to cause some kind of processor storm with heaps of ~%70 processor bursts across all cores (maybe they are %100 bursts but for a time period shorter than whatever the CPU usage sample time is).

I've not experienced this issue for the last week or so. No idea what might have fixed it as I've not tried any of the possible solutions listed here. Perhaps something came through in an update? Dunno.

I am currently experiencing this issue which goes beyond sound on my system. I can reliably re-create the issue by playing about 3 or 4 minutes of music, however once started the whole system stops without input. This includes screen updates (to the system monitor pannel applet), music and network traffic.

I have noticed in addition to moving the mouse or pressing any key (including modifiers like Shift), downloading items off the internet temporarily solves the problem. I noticed this as the problem didn't happen while the latest updates were downloading in the background. As soon as the download stopped and the installation began, the music began to skip and the installation would stall until input was given.

I have done the following tests with the following results.

Test 1: Recreate base issue. Restart computer normally, and play music. After 3-4 minutes the music and system begin to skip. Open a terminal and try to ping. As long as input is present on the keyboard or the mouse, the music and ping work correctly. As soon as input is stopped, music and ping stops. Even without music playing, ping does not continue unless input is given.

Test 2: Test in single mode without graphical user interface. Restart the computer and boot into recovery mode. Choose root shell with network, and play music using mplayer off the command prompt. Again, after 3-4 minutes the music begins to skip. Quitting mplayer and attempting ping also results in ping hanging until input is given. While in terminal mode, moving the mouse does not alleviate the issue.

dmesg and strace don't show anything obvious to me.  I am recreating the issue using music as it is the fastest way I can cause the issue, but I suspect it could be recreated with other things that don't involve input.

Another thing I have noticed is that even with the tsched hack, I will still get problems with video playback even though the audio is working. It's kind of laggy at times and I have to restart xorg.

Also if I 'Log Out' while the problem is occurring, it freezes up after closing everything and I am stuck with just my wallpaper. 'sudo restart gdm' from a terminal works (although I might need to run it twice).

I'm thinking that the Pulse-Audio stuttering is a side effect of some other problem.

I am also experiencing this bug on an HP z800. I have tried many different combinations of Nvidia (proprietary) and Xorg versions, all with no effect. I suspect that Xorg is the victim of a bug in another process rather that causing the behavior itself.

Upgrading to the 2.6.36 kernel seems to have eliminated this problem for me. http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/

Upgrading to the 2.6.36 kernel (see #19) seems to fix the flaw for me, too. Thanks!

Yeah, 2.6.36 in the mainline ppa (comment #19) fixed it for me, too. As it was a kernel issue, I marked it invalid here. I'm not sure if that is the correct label, but it wasn't the xorg people's problem in any case---sorry!

I don't think you mark it as invalid, just change the package it belongs too.

I've noticed this bug on two different machines, on a laptop with ATI x2300 and on my desktop computer with Intel 945g.

The whole user interface hangs for a few milliseconds approximately in every ten seconds. It's unnoticable during web browsing, but you can clearly notice it when you play a video or just moving the mouse around.

Upgrading to 2.6.36 didn't help me at all. Downgrading to 2.6.34 fixed the problem:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34.7-maverick/

I think this is a regression in 2.6.35 and 2.6.36, and seriously affects desktop users.

Hi <email address hidden>,

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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 661327

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
