Ubuntu :: Random Stuttering Video/audio When Mouse NOT Moving?
Oct 2, 2010
Since updating to 10.10, randomly sometimes the CPU usage will just up (although it's generally only 1 of the cores), it seems that it might be the Xorg process using it.
Audio and Video will start to stutter and the screen will stop updating so things like the terminal will appear frozen unless the mouse is moved.
When moving the mouse the screen keeps updating and the cpu usage lowers (although video still skips).
After a few minutes the problem just seems to go away until it happens again later.
i've been experiencing an issue with audio playback for certain flash videos that stream from the web. most play smoothly, like the videos at videos. others have this strange background noise that is only present when there is audio (usually on news websites that host their own videos). when there is sound, there is a strange stuttering noise that disappears during the silent pauses.
here's a perfect example: epidemic of tsa criminality: more agents caught stealing cash from luggage, another arrested for assault. the videos video at the top plays just fine. if you scroll down and watch the other video in the small box, you'll hear the stuttering. i have fedora 14 kde, adobe flash player 64 bit preview release 3 and rpm fusion codecs installed. the problem is also present in fedora 14 with gnome, same setup. the problematic videos play without the stuttering in ubuntu.
I've been having a problem with intermittent stuttering in video and audio playback since upgrading to Maverick (it also happened when I briefly installed Lucid). It started out as the odd skip every 20 minutes or so but now it can happen 5 or 6 times in 10 minutes when watching a film. I've tried:
reformatting and clean installing using a half-dozen players installing every codec I could think of (only after the normal ones wouldn't help) diangosing my 3 hard drives (the problem occurs on them all and they're not in a RAID setup) changing then changing back my video drivers disabling pulseaudio and ubuntuone-sync (these were not installed in my previous, working setup) looking at every relevant log file (mplayer, smplayer, demsg...) I know of running ubuntu's testing utilities I'm out of ideas. Going back to Jaunty is the only solution I'm pretty sure will work but it's not exactly ideal. It will be a few months a least before I'm able to install a completely new distro.
I have Ubuntu 10.10 installed at work on my Dell Optiplex 755, which runs perfect. So I decided to install Ubuntu on my home desktop, which so far has been a mistake. Booting up takes almost 5 minutes, after I login it takes about 2 minutes to get to my desktop, typing in any application (even a shell) is horribly lagged, almost to the point where the PC is unusable. I also get extreme lag when executing programs, or just simply clicking a submit button. It will take 2-10 seconds to actually click or execute. The weird part is visual effects extra works perfect and smooth.
SmartD shows my Raptor healthy, here are the read test speeds.
Min Read Rate 7.6Mb/s Max Read Rate 128.2 Mb/s Avg Read Rate: 105.5 Mb/s Avg Access Time: 8.6ms
Note: The graph has quite a few drop downs (as you can see the minimum is very low). I've also ran badblocks on the drive which came back with 0 errors. Do I need a special driver for my hard drive? I'm attempting to watch a movie on [URL] and it works fine as long as I continually move my mouse, when I stop moving the mouse the video gets jumpy.
ubuntu lucid 10.04 with the latest update up to june 6, 2010, could not play mp3 files smoothly. it always stutter randomly.i'm using gigabyte amd 780g chipset with realtek high definition audio chipset.

when i play a video (normal and full screen) there are some vertical lines appearing in the video (it actually stutters), this happens in videos and other online video sites as well. i have installed the nvidia software for my graphics card also.
I've just made the move to openSUSE* and after the installer seemed to bork my xorg.conf because of my Wacom tablet things have been going quite smoothly. My only problem at the moment is that MP3 playback through Exaile, Banshee or Totem stutters and pauses several times per track or more. The only commonality I can see is GStreamer, but nothing is giving me errors to the console.
* I ditched Fedora to get better Monodevelop support after using Redhat 7.3 and 9 followed by FC 3 and 6 then Fedora 7, 8, 9 and 10. The Ubuntu forums seemed to keep giving me occasional answers to questions, but the Suse build service gave me the RPMs, when the requirements matched.
I'm seeing regular stuttering in PAL video when running at the default 1920x1080 50Hz but not apparent when I use nvidia-settings to switch output to 60Hz. It's most noticeable when the video pans and you can see the video stutter ever half second or so.
VLC says: "main input error: ES_OUT_SET_(GROUP_)PCR is called too late" when I am playing back most Bluray discs I have tried.
See this bug post for what I am talking about: [URL].... It has to do with playing back h264 video with ALSA.
Possible fixes: 1. Obtain VLC 2.2.2 - see below 2. Fix by Modax here: https://trac.videolan.org/vlc/ticket/10422 - not currently using dmix and not sure how this will relate to HDMI sound 3. Use Pulseaudio - this does not work for me to get HDMI sound and I do not use Pulseaudio as a rule
I have just tried to compile VLC 2.2.2 and the configure script finished properly but early in the build it fails.
With make the error is:
Code: Select alljason@MEDIA:~/vlc-2.2.2$ make -j4 make all-recursive make[1]: Entering directory '/home/jason/vlc-2.2.2' Making all in compat make[2]: Entering directory '/home/jason/vlc-2.2.2/compat' GEN dummy.c make all-am
[Code] ....
And with compile the error is:

I have tried installing 3 different versions of libua-dev, 5.1, 5.2 and 5.3. What could be the problem?
With the bugged audio drivers I'm going to replace the computer but it would still be nice to be able to know the solution to compiling VLC 2.2.2.
Biggest one that make game unplayable is mouse. Mouse isn't moving smooth it jumps around. I cannot shoot anything. So i asked for help, and everybody just say install windows. And where is fun in that. If people when ever run into problem with some software on linux just install windows. Linux would never go forward. I m not some great gamer, but i would like to be able to play this game. Probably somebody run into same problem. I sow that people talk about something like dis on WOW and wine but simptoms doesn't seem same to me.
I am running Ubuntu 10.04, randomly while working in gnome with no particular application I get a freeze periodically. Neither the mouse or the keyboard will respond. I am running it on a lenovo Z61m laptop. I have had previous experience with Posix systems but I am a recent migrant from XP as my primary operating system. I never had such an issue with this computer which leads me to believe that it is not a hardware issue.
Once every, say, 12 hours of use, I find that the mouse cursor spontaneously becomes unresponsive. The rest of the system is fine, and it responds to the keyboard, but the mouse does nothing. I'm pretty sure this isn't a problem with the mouse itself, because when it happens I've tried unplugging the mouse and plugging in a different one, and the problem persists. The problem doesn't seem to be correlated with any particular program or type of activity. I realize that this probably isn't much to go on. The next time it happens, is there at least anything I can do by way of diagnosis?
I just installed and are new to Ubuntu. I have a problem with the os is constantly ignoring my mouse after about 5mins of doing whatever, then I have to restart just to get it to work again. (btw I am using a Dell USB mouse if you need to know...)
My install of 10.10 went fine with the exception of Audio. If I attempt to use audio with the Rythmbox application or through Adobe Flash (in firefox), it sounds like an old fashioned 33 1/3 rpm phonograph record playing at 45 rpms. This problem has been around for a while and I had hoped that it would be cleaned up by now.
I'm running an AMD 64 processor (in 32 bit mode) and my audio card is a "Sound Blaster Live Value" (EMU10k1X). My on-board sound card is turned off in the bios. It works beautifully under Ubuntu 10.04 and FC13 with Pulse Audio.
Originally I thought that it might be a problem with Rythmbox which is now at v 0.13.1, a later version then I have been using in 10.04. However, with the Rhythmbox application off, I still get the same effect when trying to use audio in firefox. I also noticed that my cpu utilization climbs to about 80% when Rhythmbox is on.
I downloaded and burnt the Kubuntu 10.04 release to a CD. I tried to install it. First time, couldn't find the disks and eventually it froze. Ok, second try, when it's contacting the "time server" (or whatever) another freeze, but this time I notice everything is running fine and then get a nice little image with the current time (increasing seconds and all). Third attemp, clicked the "update this installer" and it went fine. "Yay!" I thought. Well, a few minutes in my beautiful 10.04 system and again, another freeze. Hit the power button and to my surprise a "Shutdown" dialog shows up with a countdown. After 30 seconds it logs out and mouse is working again. I log back in and come here to write this long post, and as I was writing the title "Random mouse/ke..." guess what? Yeah, it froze again. And the little bar that goes after the writing continued happily blinking. Hit the power button but this time mouse and keyboard were still frozen in the login screen.
Short version: mouse and keyboard randomly freeze while the rest of the system apparently work fine.
I upgraded from 9.10 to 10.04 LTS last week (32 bit, gnome desktop, no desktop effects). The system was quite stable before the upgrade (it's usually on 24/7 with uptimes in the dozens of days), but ever since updating to 10.04, the system loses all mouse and keyboard input at random times.
I can still ssh into the system fine and reboot it in an orderly fashion from a laptop, but I'd rather that it wouldn't freeze like this in the first place
I've tried service gdm start / stop from an ssh session to see if it's an xorg-related problem, but sadly that did not help in recovering mouse / keyboard input.
I also tried unplugging and re-plugging the ps/2 keyboard and the usb mouse, but sadly that also didn't help.
I don't see any weird messages in dmesg, so it's not a kernel oops either it seems.
I'm using the proprietary nvidia driver if that matters.
When I'm using Nautilus, I've found (for years) that I've had to hit Ctrl+C, Ctrl+V or Del multiple times until the commands would register. I noticed this occurs when the mouse is moving. I've looked under System > Preferences but can't find anything. Is there a key in gconf or something that I can disable?
I boot up Ubuntu 10.04 just fine. The mouse works, but after about 2 seconds or so, it stops moving. Of course, the keyboard keeps working fine. It's like Ubuntu stops getting the signals that the mouse is moving. The mouse is in fine working condition. It works fine on my Windows partition. The mouse just had fresh batteries installed, and the laser light doesn't turn off.
I did just remove an ATI card and go back to my GeForce 8200 onboard graphics card. So I thought it might be a wierd driver problem, so I managed to remove the NVIDIA drivers. Didn't help at all. I also was able to log into a console and update the OS. No help there either. I did try to boot my 10.04 live cd, but my computer hates live cd's for some reason. It wouldn't boot, and I can't remember what I did to make it work when I installed Ubuntu.
I've had this problem in the past, but it's more frequent for me now. Running Ubuntu Karmic (9.10), and if my browser is open long enough the audio in flash dies until I restart my browser. I'm running Chromium (non-google branded). I'm fairly certain this is happening in Firefox too.
When I don't move my mouse, my screen pauses and stops doing anything. I constantly have to move my mouse to refresh what is on the screen. For example, if there is a video on the screen, the video will stop and glitch up if I am not touching the trackpad to make the cursor move around the screen. The second I start to move the cursor on the screen, however, the video plays again. Why?!
I have the strange problem that my sound and video stops sometimes when I'm not moving the mouse. As long as I keep moving the mouse there is no problem.
I am using
- Fedora 14
- 2 Sound cards (Internal Audio and Audio device on my Radeon HD 3600 video card, however this sound is not working)
I've got a problem with my Arch flashdisk. When I start xorg, my mouse cursor keeps moving left until it reaches the edge of the screen, where it stops. I checked the connector, etc., but it didn't help, so I guess it's software-related.What can be causing the problem?
I'm having problems keeping audio working. Using Sparky with 3.16.0-4 kernel on a homebuilt PC. AMD A10-7850K CPU on a Gigabyte F2A88FN-WIFI mobo.
I'm using a set of Logitech Z-5 USB speakers and I repeatedly lose all audio output. To get it back I need to do 1 or all of these steps:
1) Unplug the speakers 2) Kill all processes that may be producing audio (Chrome beta, IceWeasel, Exaile, etc.) 3) Start Alsamixer and select another source in sound card list then reselect USB card #2. 4) The weird one - Remove and then re-add the volume applet that I like to have in the panel. When I lose sound th slider gets "stuck" and will not move. It will not recover.
I may need to repeat this several times but it will come back. Not immediately after any step but after a few attempts it just begins working as long as nothing is trying to produce audio at the moment. Sometimes Alsamixer says that my USB Card has no controls when I reselect it, not every time though.
Most of the time if I have more than 1 source open at any time it is likely to die again, for instance I like to stream Google Play Music. If I pause that but leave it open, then try to watch a Youtube video or other source I will either get no audio from either source, or lose the streaming audio source when I try to restart it. Going through the above routine 1 or more times usually restores it.
I have created asoundrc.conf file to tell system to use USB audio as described here -> [URL] ..... In my case USB is # 3 in the list. So this is my file:
Code: Select allpcm.!default { type hw card 2 } ctl.!default { type hw card 2
I have a video file in which the audio runs faster than the video, so they quickly go out of sync. The way to fix it would be to separate the audio and video streams, speed up the video (the audio is FINE, it's the video that's wrong), and then recombining them. What is the easiest way for doing that?
An ubuntu-11.04 laptop is set to turn on the screensaver after 5 minutes of inactivity, and power management is set to blank the display after 15 minutes of inactivity. When the screen goes blank, you're supposed to be able to move the mouse to return to your Gnome desktop. This works sometimes, sometimes not. When it doesn't, moving the mouse doesn't eliminate the black screen, although I can see the mouse cursor. ctrl+alt+del does nothing, neither do alt+tab, alt+esc or ctrl+alt+esc. ctrl+alt+f1-12 work as they usually do, so I can "sudo /etc/init.d/gdm restart" from one of the TTYs, or via ssh.
I tested just now with setting the screensaver and power management display blanking to 1 minutes. After a minute the screen went blank (backlight on), and then after a second or two black (backlight off), and moving the mouse returned to Gnome as it should. So I don't know why sometimes it doesn't. Two questions:
1- Which program can I run, or which service can I restart, to return to Gnome without having to kill gdm and lose all open windows?
I ping my router. If I keep my mouse moving (or i'm typing) I get a 5ms ping.If I stop typing/moving my mouse, it times out.
- I disabled NetworkManager for the inteface eth0 but it doesn't solve the problem. - I'm having the same problem using a Ubuntu 15.01 bootable image - I'm having the same problem usign an Ethernet PCI Adapter - I'm having the same problem usign a Wifi PCI Adapter
