Ubuntu :: (Maverick) Severe Lags In Various Applications
Nov 14, 2010
Sometimes (not always, mind you), several applications, lag. A lot. For instance, Blender 3D is entirely unusable and don't get me started on Fallout 3. Other examples include Minecraft (Not the Windows .exe but the .jar) and XMoto. So I assume it has something to do with the graphics driver or the likes. For some reason, Compiz still works fine. The only way I can fix those lags is to reset X, which is not exactly a good way, especially because this happens to shut down uShare and thus cancels my movie stream. So..
For support reasons, here's my setup:
CPU: Intel Core 2 Duo E4500 (2*2,2GHz)
Graphics: Nvidia Geforge 8600GT, 512 MB
2 GB RAM
500 GB HDD (The Maverick partition is 159 GB, 2 GB Swap)
Some hama WiFi-Stick
ForteMedia something something audio card

Since I upgraded to Maverick, every now and then (maybe once an hour) my system becomes very slow for about half a minute. The mouse cursor reacts only very slowly and also applications freeze for for some time.
This happens without the CPU being on full load or the hard disk being active.
I made a clean ubuntu installation on a new hard drive a week ago, but the problem persists.
I have a Thinkpad R400 with an Intel GMA 4500 graphics card an an Intel T5670 Core 2 Duo processor. I'm running the most up to date stable version of ubuntu. Kernel 2.6.35-22.
I know the description of the problem is very vague, but it's hard to describe it more accurately. I couldn't find anything helpful on google or the forum. If you have any ideas what might cause the problem or which log files might provide useful information, please let me know. Most importantly, the problem did not occur before I upgraded to Maverick.

I would like to kindly ask you for some advice. Allmost a month I am experiencing strange behaviour of the system. I use Debian Wheezy 64bit on Intel Core i3 processor, SSD hadr drive, 4GB ram. Problem is, that sometimes the system becomes very slow when booting kernel, the kernel booting stops for 5-8 seconds on something (timimng, Processor initialization or something related, but not always the same thing) and then the system is booting noticeable slower than usual and when in the graphic environment (I use gnome) everything seems to be slower than usual, the typing in console is slow with lags and videos (movies) are not watchable due to freezes and lags.
I was trying to figure out what is causing it, the only thing I came up with is, that when I wait 10-15 sec in grub menu before selecting the kernel and after some time I manualy hit enter, it usualy boots fast and with no additional issues in the system. Sometimes it boots up normally even without this longer waiting time, but sometimes not. It is strange.

My mouse and trackpad button control is severely impaired in 11.3, KDE 4.5.1 (or .2) using Compiz. Gnome works fine. XFCE has some problems. The mouse control of window features is sometimes limited to one window with the rest of the desktop not responding to mouse actions. Popping up a second window from an app causes the mouse control to be completely lost. The issue leaves KDE effectively broken having only keyboard control. With some ESC key hits and using right mouse button to close one app (from the panel), I can move focus to another app but mouse control within the app is non-existent. Moving windows or raising or lowering doesn't work either. Sometimes, the GUI captures the mouse click but does not recognize the active App and applies it to objects sitting on the desktop screen underneath.
I've reverted partially back to the 11.3 installation DVD then reload updates and then moved to stable release of 4.5, then went back to the 4.5 factory. All failed to correct the problem. I removed .kde/.kde4 files and this did not help. What is wrong with my system? Also installed the latest kernel of the repos then reverted back to 2.6.34.7-0.3 [x64]. [very frustrating, been using Suse/KDE for >7 yrs, this one has me stumped]

I am not sure of which LibreOffice version I am using because I can't open the ****ed program. So here's what's happening: I start LibreOffice, my screen looks unusual (it tiles a section of the screen that is the same size as the LibreOffice window (I think) across both of my monitors) and my system locks up. I am unable to use Ctrl+Alt+Backspace, Ctrl+Alt+Delete, Ctrl+Alt+F1-F8, or any other keyboard combination. No mouse click registers and the cursor acts as if the mouse is in one location (if the system locked up with my cursor over a link, the cursor stays like that) BUT the mouse still moves. Also, if I am playing music when it locks up, I can continue to hear the music and the music continues to shuffle through my playlist.
I am able to access my machine normally through ssh and the only way I've been able to fix this is to hold down the power button or pull the power. I have not identified what action causes the system to lock up, the only thing I've noticed is that LibreOffice is open every time this happens (It's happened no matter if Writer or Calc is open). The system almost always locks up upon startup of LibreOffice if the recovery window pops up, otherwise it locks up at some point during my LibreOffice session no matter what. I have not touched LibreOffice on my other machine's openSUSE installation, so I don't know how reproducible the problem is. Let me know if you need any extra information or if there are any diagnostic commands I could run.

Running Ubuntu 8.04LTS at present. (hyperthreaded 3.06 with 2gb ram)
Have Logitech 9000 web cam .. brand new out of the box.
It installed and works both in Cheese and in Skype. (outstanding image!)
But, there is a severe lag in the image (audio does NOT lag .. so makes using any on line VERY hard to do!) Is there some way to get this thing to work properly, or am I going to have to wait on 10.04 to see if that works? (hate to use the old saw of "it works in Windows", but it DOES on my Windows machine .. just that I want it to work on the Linux box as that is my primary box and used for almost all on line activities.)

Anyway, my internet has been working fine until recently (last week or so). For most sites, Firefox will load the page quickly. However, every once in a while, but frequently enough to annoying, it will say "loading" for 10 seconds, then direct me to OpenDNS, which says the page cannot load. When I try it again, I get the same problem. Other sites are fine.
Then, when I quit Firefox and restart it, that site will work fine, but soon enough, another site stops loading properly.
For example, Google will work fine for awhile, then I'll get the error, but after restarting, Google will be fine again, but now Wikipedia, which loaded before, gets the error. And the cycle continues on yet another website...
I haven't changed any Internet or network settings recently. I'm on Ubuntu 10.04.

I was running Debian Etch for a while and upgraded to Debian Lenny months ago. After the upgrade I began to notice that I was losing time pretty severely on the desktop clock (On the order of more than 1 second every minute!).I recently noticed an online game lagging exactly every 5 minutes and finally pinpointed it to this timekeeping script I wrote. I would like to fix the time drift issue on this PC properly now but have not found any helpful documentation online yet.

I have Ubuntu 10.04 installed on my Dell Dimension 9100 it has a dual core 3ghz possessor. 2.5 gigs of dual channel ddr2 memory, with a nvidea gforce 9400 1gig of memory graphic card. I installed the game a couple of weeks ago, everything works really good, but in the last couple of days when I am playing the game it starts to lag really bad during game play, it goes in and out of the lag, if I wait 10-20 seconds it will get back to normal, but it is very annoying.

Today I noticed a large sound gap while playing Minecraft. There is about a second of lag between an action and the sound effect. This wasn't happening the night before, and I thought it might be a problem with Java or Minecraft until I noticed it on a flash application in Firefox. I've tried killing pulse audio, but I noticed nothing. I also looked into the sound preferences and tried the speaker test, which had no lag.
Other possibly relevant information : I dual boot my laptop with Windows 7 and Ubuntu 10. Ubuntu has some updates ready, but I don't believe its relevant because the problem just started.

I have a problem multitasking in ubuntu. all i want to do is be able to browse the web or play a game while listening to music, currently trying to do this slows or makes music lag.I have a dual core processor and 2 gb of ram, and ubuntu runs lightening fast, even while multitasking everything but the music runs great. i can do this in windows, so i dont see why i cant do it in ubuntu.
i have watched my cpu and ram monitors while doing this and there are plenty of unused resources, i believe neither processor core ever tops 20% while trying to do this, and ram, 7%. I want ubuntu to use the extra resources instead of taking away from my music playback. And what i mean by games are like quadrapassel and simple stuff, im not trying anything difficult. So my question is; Can i make ubuntu use more resources, or never sacrifice music quality?

I am running Linux Mint Isadora 9 and recently installed a wireless USB adapter. After installing RT3070 drivers for my RT2070 card I got everything working and life was good. Now, all of the sudden I am having a world of problems connecting to the internet. I can connect to my AP fine, but I cannot access the internet. If I attempt to ping my AP by IP address I get severe packet loss. I cannot ping my AP by url [URL] at all so Im guessing there are some DNS issues as well.

we bought a dual 12-core Opteron machine (Supermicro H8DGi board). Installed Slackware 13.37 and performed some few tests. We observed that performance quickly degraded as the box became loaded. For instance, a lonely task may took "t", but when running 24 of them at the same time (fully loaded box), it may took 2 to 3 times longer. From some test we did (tinkering with BIOS, moving memory modules, etc) we came to the conclusion the problem was due to a terrible memory managment. Finally we solved the problem by recompiling the kernel and taking the .config file from OpenSuse. Thus, there must be something to be tweaked in the standard Slackware .config file

I use an online screencasting java applet called screencast-o-matic to record my screen. While recording, I use Compiz's annotation tool. Normally this tool works great, but for some reason while I'm recording, it gets very laggy (drawing is way behind the mouse movements) and less smooth. For example, drawing a circle at a quicker pace not only causes lag, but also makes the circle look more like a polygon with straight lines. While this is happening, my CPU also spikes, with large strains showing up on the java process. I'm running Ubuntu 11.04 with an intel i7 processor. Any ideas as to why annotation lags badly while screencasting, and any ways to fix it,

After I upgraded from kernel 2.6.32-31 to 2.6.32-32 and then 2.6.32-33, my sound started to lag(the lag occurred on 2.6.32-32 and stayed to 2.6.32-33, but it worked perfectly ever before). Sound does work in itself, but frequently lags and pieces that were already played before will be played again, pretty much like an old vinyl that occasionally jumps or hangs. When I start to replay something, it does not put out anything for a second or two and then starts, when I stop it will keep playing for the exact same amount of time. So, sound is synced to videos(video replay works perfectly well and without the lag). Problem is definitely related to the sound drivers, not to replay software or any buggy file. It occurs with DVDs, Flash Videos in Firefox, music in gmusicbrowser, movie files with VLC, whatever you want. I never experienced such problems with any kernel before. Although I've seen many others posting similar problems, I cannot see any valid solution for myself.
I'm running Ubuntu 10.04 and I sure don't want to go to 10.10 for the second.
I reinstalled Alsa and Pulse, no joy. My sound card is recognized correctly by alsa and can be found in aplay -l. It's a generic onboard surround sound device, although I only use stereo channels.

Why system lags so much while working with a lot of files or with big files (copying them, erasing)? How it can be solved? I am running Fedora 12 x86_64 with ext4 filesystem

The program mplayer lags when playing high quality media over the network. This is not an issue when playing locally, but it becomes an issue when playing large (>= 1 GiB) Matroska video files over the network.
By "lag" I mean that the animation freezes at a fixed frequency, every five second or so the animation will halt for a fraction of a second, which is very annoying.
The network is a 100 Mbit switched ethernet network, I typically get around 10 MiB per second in actual flow rate and there is no noteworthy traffic on the network that degrades the performance. The lag is there regardless of traffic.
If I have a file at 1.4 GiB which is 60 minutes long, shouldn't that equal < 0.4 MiB/sec in required flow rate? I.e. I should be able to play this file over a 10 Mbit network. Yet, even on a 100 Mbit network this doesn't work.
The computer I use to play this media is a 4.12 GHz Core i7 with 6 GiB RAM and a GTX480 graphics card.
I have the latest graphics drivers. I use Slackware 13.1.0. I use a custom, small and highly optimized kernel (although the same issue is there with the standard kernel). My version of mplayer is MPlayer SVN-r31498-snapshot-4.4.4.
The network protocol used is SMB, i.e. I play from a mounted SMB resource.
I have tried to host the file on different computers, both are dedicated file servers, one is a Pentium 4 3.0 GHz with 2 GiB RAM with no load other than hosting files, the other being almost equivalent except with a 2.8 GHz CPU. Watching the system load on the machines yield nothing of interest, sending a mere ~0.5 MiB per second is nothing for a computer like that, even though a P4 is not exactly new anymore.
What is interesting though is that if I use the "-vo gl" argument to mplayer, the performance is greatly improved, there is very rarely any lag.
Now correct me if I'm wrong, but why on earth would the video output driver chosen affect the performance on a machine that has a 4.12 GHz Core i7 CPU, plenty of RAM, a very fast graphics card, and nothing else to do? I.e. no load at all? When I use the standard output driver, there is almost no load at all on the system. So what the heck is this?

It seems every 30 seconds the internet lags, after that it is fine for 30 seconds. And this happens continuously. Also it seems when I am on Firefox if I am connected to a website, I can navigate the website with not further trouble. But if I navigate away and try to go back, it takes a while. I didn't update, or upgrade or anything. I am running 13.1 and have been since it came out. This just started with the internet 2 days ago. Also I have a dual boot with Win7 and the internet is fine on Win7.

Alright, on my last Linux installation I know I did not get graphics lag this bad.
So I go to move a window around, Nautilus, Firefox, a Terminal, and when I move it it takes a second to reach the location and refresh on my screen, and if I move my mouse within that time period then it will move the window somewhere I did not want it.
I disabled Smooth Scrolling in Preferences => Advanced => General for Firefox but I do not think it helped. It takes ages to scroll to where I want it and by the time it gets there it keeps going because I scrolled too many times. I receive scrolling lag on seemly any document of text, this includes gedit as well.
I'm working on finding out what graphics card I have so I can see if it has Linux drivers. I know it is an ATI, but I have no idea how to get its name using Linux commands.

ever since i started using opensuse at the end of december, this has been bugging me. when i try to watch a full-screen videos video in either chromium or firefox, it lags to the point where maybe i'm getting 0.5 frames per second. ironically, when i launch chrome in virtualized windows 7 (virtualbox) to watch a full-screen flash video it looks smooth as butter. yes, even with the virtualization overhead and everything.
i'm using adobe flash 10,3,181,22 from the opensuse repositories, chromium 15 and firefox 5. i'm on a 64-bit system.

I am running gnome 3 on ubuntu 11.04, a clean installation from the gNatty version, 32 bit. The machine is a Lenovo t420, with 6GB RAM and a integrated video card.
Everything is running smoothly but not for games. I tried urban terror, Tremulous, Nexuiz, all of the lags from the very beginning as if I was using a machine 5 years ago to run today's video games (ie, takes 10 seconds for a mouse move a show, audio lags, .etc). From my experience it should come from video card driver not installed, but the update manager shows all device works fine (indeed, the screen resolution is 1600X900).
