Ubuntu Multimedia :: Maverick Compiz Choppy/high Cpu Utilization?
Jul 7, 2011
Been using Maverick on my Dell Studio XPS for many months without issue. About a week or two ago, compiz has been acting funny and using a lot of cpu time, making everything "choppy," especially after resuming from suspend. I've googled and searched the forum, but all the related posts seem to be several years old.I tried selecting the previous kernel but it didn't help. Was there a bad update to compiz or ati graphics?
My info:
Code:
> lspci | grep VGA
21:02:00.0 VGA compatible controller: ATI Technologies Inc Madison [Mobility Radeon HD 5000 Series]
> grep -i driver /etc/X11/xorg.conf | uniq
Option "VendorName" "ATI Proprietary Driver"
Driver "fglrx"
[Code]...

I am getting a strange problem with my new machine (P4 3Ghz, 1 GB RAM DDR333). The machine is an industrial PC. Firstly I had installed Fedora Core 2 on it. It ran superbly without any problem. I tried to load Redhat Enterprise Linux WS4 (Update 2 as well as Update 5) on it. But the PC was giving high CPU utilization for each and every task. With-out any application running both the cores shows utilization around 10 %. But when i try to my application, the CPU utilization in one of the cores goes to 100 % for majority of the time. This is causing my appilcation to run slowly when compared to the same application running on the same machine under fedora core 2. (CPU Utilization around peak 17 % in either of the cores in Fedora Core2) Recently I installed Cent OS 5 on it. But the behavior of the PC remains the same as of Redhat Enterprise Linux WS4. Some-where on the forums I had read about the RAM size. So i tried to downgrade the RAM from 1 GB to 256 MB. But the problem remains the same. I think it has to do with some kernel tweaking.

I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]

mapped: 33384K writeable/private: 3352K shared: 20504K
But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si
Mem: 3895444k total, 3163192k used, 732252k free, 352344k buffers
Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached
Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.

I installed the NVIDIS driver for 64b Linux, and now I face a high cpu utilization (up to 40%) in the XORG when I swith from one application to another. I need the driver because otherwise some web pages are rendered with a something like a watermark

Running 10.10 with compiz and gnome
The whole screen goes dim for any of the below examples. running "compiz --replace" fixes it until any of the below happens again. When the screen is dim, a new window opened (ex: firefox new window or a new gnome terminal) is full brightness while the rest of the screen stays dim.
Following causes the screen to go dim: In the screen saver - hit the delete key to backspace when the password field is empty. in firefox - ^f to find on a page - start typing and as soon as the find field has text that does not exist anywhere on the page "Phrase not found" the screen dims. in gnome terminal - the profile has the terminal bell checkbox ON - hit backspace on a bash input line with no text on it.

Pentium 4, 512MB RAM, GeForce2 MX/MX 400
When my machine ran Windows XP, I was able to watch full screen videos on Hulu, etc. with no problem. Now my machine is running Ubuntu (Koala). I'm using Firefox with the most recent Adobe Plugin (and I've made sure there are no other flash players installed). Streaming video (at low to medium resolution) is pretty choppy but still watchable most of the time. It is not watchable when played full screen or with high resolution. When I download the .flv file and play it through VLC, everything is smooth. Are there any tricks I can try to get the video running more smoothly, like it did before? (Disabling desktop effects made no difference.) Should I just get some more RAM? (I realize my RAM is low, but it didn't seem to effect my video watching before.)

I'm having issues playing HD videos ( some with 720p level, much more apparent with 1080p level one) The video appears to slow then becomes choppy, becoming de synced from the audio that carries on as normal. This occurs with both VLC player and XBMC, though the latter is better. My specs: Fedora 12 3.2 Ghz P4 processor 1Gig ram Radeon 9800 xt gfx card (I couldn't get the 9.3 ati driver to work)

It's the fourth time now since Maverick that I had to cold reboot my system because it was totally unresponsive. The system monitor in my taskbar shows 100% on the background blue graph (I guess that's just one core then) and almost nothing on the other core. On the last freeze I managed to open 'sudo top' before it went totally unresponsive and saw that there was no high CPU usage at all, but a load average spiking above 24. Also the swap seemed to be full although my machine usually never uses swap. I was watching a movie with VLC this time, but I'm not sure if VLC ran the other times my OS froze. I made a snapshot with my cell phone: [URL]. How I can prevent a process from causing so much load?

I've heard that Compiz is not working in Maverick. Is this true? Has it impacted computers with decent graphics cards much, or is it no big deal? I'm kinda confused, because of the Ubiquity thing. Is that replacing compiz?

I upgrade to 10.10 via online upgrade yesterday morning. All seems to run fine, and before the yesterday afternoon upgrade, compiz appears disabled and each time I try to enable it I get the error message.I checked the direct rendering is working. Google Earth works fine also, so all seems to be OK.
My system: Eee PC 1201n, Nvidia Ion, 4 Gb Ram, 320Gb HD
Ubuntu Maverick updated.

I can hear everyone clearly but when I go to talk, my voice comes out choppy. However, when I use Sound Recorder to record myself, everything plays back clearly.

i'm having choppy sound in 10.04. i didn't have it in 9.10 and i don't know enough about how it works to try to fix it.
here are some things i have noticed, however.
1. the choppy sound is present in a 64bit and 32bit install. at first i thought it may just be a 64bit issue so i reinstalled to 32bit and it is still present.
2. it does not seem to matter what media type i am playing. i notice it most with videos from videos and music from pandora.
3. it seems to occur more often at intense moments of music. i'm not really sure how to describe it, but it is typically the climax of a song where it is a little louder and more intense.

I've been browsing through the forums and tried several things, but I haven't found a solution to my problem yet. I have an Acer Aspire 5520 laptop, with an NVIDIA GeForce 7000 M graphics card. For a year I've been using Ubuntu, and with all the versions I've had, through Gutsy to Lynx, I've always found that 3D graphics are extremely choppy. I wouldn't say they are slow...it's more like they move for a couple of seconds, then stop, then move again, then stop. I didn't really care, because I hardly play games: I had initially noticed it trying to get Warcraft 3 to work on Wine, which obviously is an old game, and it runs perfectly on windows...I thought it was just a problem of Wine. But now I've installed Celestia and Flightgear, and with both of them I have this same problem. Flightgear is the worst, it's basically unusable.
I have done several things based upon what I read in the forums. I removed all the NVIDIA drivers, and manually installed the latest propietary driver 195.36.24. I turned off all my desktop effects. I turned on Sync to Vblank to see what would happen. The desktop itself runs very quickly, even the Desktop cube effect, if I turn it on. Like I said before, the problem seems to be this jerkiness with games, with Celestia, and with flightgear. If I get this working, then I'll actually have Ubuntu working completely perfectly, for the FIRST TIME!

When I play streaming video on hulu or other sites it is choppy. However, the sound is fine. Video files play fine when I download them.I experience this problem in both Firefox and Chrome. I have a 10MB connection on other Linux desktops the streaming video is fine.I imagine it is a flash issue, but I have the latest flash v10.1.The other solution would be a video downloader for streaming video. I have not found one that works on Linux.

Im trying to play some videos with vlc but they are too choppy, I guess my comp is too slow. They are something like 1700x1000 h.264. What can I re-encode these too to maintain good quality but increase playback speed? If possible, an ffmpeg command to do this would be awesome.

I've got a Lenovo T410 with just the onboard intel graphics, with the i7 620m and 10.04 64-bit installed.I've also added the xorg-edgers ppa and installed all the packages from there. When I try to watch a 720p video full-screen in ..... it is unwatchable, just too choppy. I haven't been able to find an answer to this elsewhere. I've tried disabling the hardware acceleration in flash but that does nothing.
It seems that the driver in use is i915. Is that the driver that should be used? From lspci: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

When I am scrolling using my touchpad on my Dell E1505 regardless of which program, my sound skips. Its like it becomes scratchy or similar. I had the same problem with 10.04 and fixed it by modifying some modset file. Said it had something to do with my ATI X1400 GFX card too.

I'm running Ubuntu 11.04, have 4GB of Memory, and an AMD Phenom II X4 840 Quad Core processor.When I play Hulu Desktop the video is choppy.Now, the odd thing is that I had this problem before. It's the whole reason I upgraded my processor. When I upgraded I noticed an improvement, but it was still a little choppy. I then went to the Adobe site and got the latest version of Flash, and lo and behold, I could watch Hulu Desktop on HD quality with no problem!

I'm running an athlon II X2 on a Gigabyte GA-MA785GM-US2H motherboard Graphics are running on the Radeon HD 4200 on the motherboard. System has 2 GB of RAM. I recently did a clean install of Ubuntu 9.10. I previously had 9.04 installed and flash video ran completely smoothly, and the CPUs wouldn't even come out of 800 MHz power save mode.
Since upgrading to 9.10, flash runs choppy and the CPUs max out every time there is a lot of movement on full screen videos. On 9.04 and 9.10 I was running the ATI proprietary FGLRX hardware drivers. I've tried re-installing the ATI drivers and flash. I've also disabled compiz desktop effects.

I just upgraded from Karmic to Lucid. I've never had problems with playing video files before, but now that I've upgraded to Lucid, I am, regardless of Compiz and other visual effects being on. What I know of my hardware specs are in my sig. I have "NVIDIA accelerated graphics driver (version current) [Recommended]" activated (and in fact, one of my reasons for upgrading was the supposedly improved NVIDIA drivers in Lucid). VLC, MPlayer and Totem are all choppy playing .avi's: they play smoothly for several seconds, then start skipping (audio and visual, separately), though VLC does so less violently than the others. Similar problems, though slightly less severe, with watching flash movies in chromium.

I am having audio issues in my host operating system (Ubuntu 10.10 64bit) when running my Virtual machine (Windows Server 2008 R2) through VirtualBox. At the moment I need the virtual machine to run all the time my issue comes when trying to play a movie on the host OS, video is fine but audio is choppy to the point of not understanding what is being said.
I used gstreamer to test the audio outputs while the VM was running, ALSA is choppy but Pulseaudio is clear. I then change VLC to pulseaudio and I get no output what so ever. The VM does not need sound so I have it disabled in VirtualBox's settings (I have tried enabled, same issue).

Streamed videos on various Web sites are slow and choppy for me. The problem seems to be a cross-browser issue, today I did an informal test of various sites I frequently use on both Mozilla Firefox and Chrome. The results of my informal test are below, and as you can see they are mostly the same for both Firefox and Chrome.
Google Chrome-
You tube-- no problems once video loads, but loading is slow
Daily show-- very slow loading, sound ok, video extremely slow, choppy, unwatchable
ESPN--slow to load, sound ok, picture is very slow, choppy
eHOW--slow to load, sound ok, picture is very slow, choppy
Mozilla Firefox
You tube-- no problems but sometimes slow loading
Daily show-- a little slow loading but sound and picture ok
ESPN--sound ok but picture very choppy
eHOW--slow to load, sound ok, picture is very slow, choppy
Other data:
Ubuntu 10.04
Toshiba Satellite A100
432.8 MiB memory;
Intel Celeron (R)M: 1.40 GHz.

I just upgraded to Ubuntu Maverick v 10.10 and loving it. However, I have encountered a problem with playing any type of video whether it be Xvid, AVI, h264, MKV or AAC. I have tried many players from smplayer, mplayer, kmplayer, vlc, etc. but I am still having the problems. I have read some posts on here and I've disabled compiz, tried the X11 tweak and updated my Nvidia drivers. I don't know if I am missing some type of codec or restricted plugin because I have ample space and resources are readily available while playing the video.

I have three different webcams. All Logitech. Two are "cheapo" ones, and one is a more expensive, HD one. I'm running the stock Maverick desktop install, with no specifical extras for the video or the like. I plug in the webcam (doesn't matter which one I use) and it is picked up and can be used. Not a problem, but when I view the feed, the its laggy and choppy. If I plug in the cam onto my Windows XP or Window 7 installs (on the same laptop), the feed is smooth and has no issues. So I figure it has to be something to do with my settings or configurations. Problem is, I can't seem to find out what I need to tweak to smoothen or improve the feed. I've tried reducing the resolution of the feed to the minimum, but that hasn't helped.
Just to give you an idea of what I'm talking about. If I film myself typing at my laptop keyboard, I can see my hands move around the keyboard when I view the footage in Windows, but when I film it in Ubuntu, it's very jumpy, and my hands seem to jump about all over the keyboard -- almost as if something can't keep up.

currently using nvidia accelerated graphics driver (version 185) and a nvidia 8800gt. cpu is an intel c2d e6600, so it's quite a fast pc. video playback is extremely choppy to the point of being unwatchable. it affects all applications that i have tried, such as vlc, movie player and flash videos in mozilla firefox. videos on videos seem slow but playable, but when i try to watch them in full screen there's a drop to about 5fps. cpu usage reaches 100%. scrolling is also slow on large webpages. disabling compiz makes no visible difference.
before i installed nvidia's driver, videos played perfectly. videos play fine in windows xp. it seems as if nvidia's driver is using the cpu to 'process' videos, instead of the graphics card. other than that, ubuntu 9.10 is lightning fast... so what's going on here? i have resolved one issue, that is flash player's performance in firefox. followed instructions [here] and videos is now smooth in full screen. other videos, however, are still stuttering and spiking cpu usage. this must be a widespread issue, but the lack of information on the web shows otherwise.

I have a ASRock ION 330 with 512 Mbyte shared graphics memory. I use the 256.44 closed source nvidia drivers and have a Xinerama display consisting of one Asus 1440x900 monitor and one video projector with displaysize of 1280x720. Display: 1440x900 + 1280x720 in Xinerama
I have tried with and without desktop effects enabled, and I have followed the http://tombuntu.com/index.php/2009/0...thout-tearing/ guide to manually set the refresh rate to 60 Hz. The sync to Vblank option is checked, both in CCSM and nvidia-settings under X Server Xvideo Settings and under OpenGL Settings, to no avail.
The files I play are MPEG-2 Transport Stream in 720p. Some are and some are not in Matroska containers. I use SMplayer with vdpau enabled. I've made a comparison of Windows Vista and Ubuntu 10.04 below:[URL].. It's not entirely clear from the video, but the end scroller is choppy on Ubuntu and relatively smooth in Windows Vista.
This setup is to be run in a public cinema, and the chopping and tearing is a complete showstopper. It would be a nice showcase to have Ubuntu in the wild like this, but it can't be used if these issues are not resolved.

I installed Ubuntu 10.10 recently and I love it. Everything works great except for video playing. When I try to play DVD's with VLC or ANY video player, I get horizontal flickering and I can't seem to fix it. I re-downloaded and installed the most recent video drivers from Nvidia and it did not change anything.
My video card:

I don't know what else to do. When I run windows, the videos play smoothly, just fine. But when I play the same DVD's under Ubuntu, it's choppy.
