i recently caved and upgraded to ubuntu 11.04, despite my hate of the unity interface. anyway, i seem to be having completely random, massive lag spikes! seems to happen when i do certain things, such as spend to much time on videos, or stream hd videos. playing games, such as minecraft, and using skype seems to be giving me the same issue. i don't know what to do! i haven't found anything similar to this in my google searches,
View 6 RepliesI am having a bad slowdown issue when I enable Visual Effects with the Ati proprietary drivers that come with the installation. Everything runs very slow maximizing and minimizing take about 3-5 seconds per click and the effects get all choppy and don't look right like they did on my x1950 video card. I have tried downloading the current drivers from the ATI site but they don't seem to be initialising correctly after I perform the install.
I also know that the graphics card is not the culprit as it works perfectly fine on my Windows 7 64 bit install. There is no reason that my video card cannot handle the Visual Effects as it is a 1GB 4890 should have more than enough horsepower.
My machine is:
AMD Phenom II 965 Black Edition
8 GB G. Skill 1600 DDR3 Memory
1 TB Western Digital Caviar hard drive
1 GB 4890 Graphics Card ATI.
Anyone seeing a dramatic slowdown and "PAGE NOT FOUNDS" after the latest updates?
It even happens on LAN activity. Peak speed is excellent, the ability to resolve both local and WAN addresses is very spotty.
Machine is a newer Clone with AMD Phenom II dual core with 2gb running 10.04 32-bit with Gnome. Network is Gigabyte MoBo 1000-T ethernet hardwired to Dlink router into cablemodem.
XP and Win7 aren't affected.
It was ripping this morning, but right now, is pretty much crippled.
I have Ubuntu 10.04. I installed the KDE libraries to use Okular. Then Ubuntu took almost 30s more to boot (20s black screen between login and desktop). I uninstalled KDE, booted on another kernel, rebooted and the boot time was OK again (25s).
I reinstalled KDE, 55s to boot again. Rebooted couples of times always the same. Rebooted on another kernel then again on mine (it seems to fix the slow boot times).
Boot time was 35s (I thought it was OK). After lauching Okular, the boot time was again 55s...
Removed KDE, Okular, and the boot time is normal again since 10 reboots..
Does anyone else have problems when loading an animated gif in firefox? After upgrading to natty, firefox eats 100% of cpu each time an animated gif is displayed on the tab title, or when the favicon is an animation. I have an fglrx driver, but opengl animation doesnt slowdown pc as much as favicons does on firefox.

So found one issue: When torrent upload speed reaches peak speed (160-200 Kbytes/s) huge read slowdown happens. Server becomes almost unreachable... It allows to connect via putty but it takes a lot of time.
Tested top stats during those lags (Deluge, Transmission) - 10-15% CPU usage.
So I think the problem is in LVM and not in CPU.
How is it possible to find weak place in system to avoid those lags... Cause if torrent is seeding it's impossible to watch movies through network form that server.
I have noticed that when iptables is active on my router i get a noticeable slowdown on browsing. This is untraceable through traceroute:
Code:
traceroute -n www.a-site-here.com
finishes immediately and at the same time when loading the site on firefox I am getting timeouts.
I use firewall builder to configure iptables. I have removed all rules while trying to find the one causing the problem, but even disabling all rules does not solve the problem. So, by leaving only an "accept-all" rule on firewall builder(so i don't lock myself outside) I still get slowdowns. In this case
Code:
iptables --list-rules
gives:
Code:
-P INPUT DROP
-P FORWARD DROP
-P OUTPUT DROP

Does anyone else find that Openoffice 3.2's spreadsheet app becomes unresponsive when copying and pasting multi-cell selections? I've had this problem ever since I started using Ubuntu 10.04, which comes with OO.O 3.2. The problem becomes noticeable whenever I make a selection more than about 8-10 columns across. Once the flashing border appears around the selected cells, the spreadsheet app becomes very sluggish. The mouse still moves normally, but it takes several seconds after a click until the highlight moves to another cell, or to un-select the cells, or copy them. These slowdowns happen both in old spreadsheets and in freshly created ones. They didn't happen with Openoffice 3.1 or earlier. Haven't tried it under Windows, so I'm not sure whether this is an issue specific to Linux OpenOffice 3.2. Other apps don't seem to be affected.

If I initiate a file copy of more than a couple of GiB, the PC goes into a dramatic slowdown. Even selecting a different subdirectory through Nautilus can take 30+ seconds.Now, whilst I appreciate that file copying puts a load on the bus, DMA and, to a certain extent, the CPU, it seems unconscionable that it makes the PC effectively unusable until the copy has completed.Is there any way to (practically) lower the priority, or similar, of the copy process so that one can continue to use the platform during large file copies? Right now, I end up using a laptop adjacent to the PC whenever I have to copy a large file. This, for a mainstream operating system is, frankly, ludicrous.I'm aware that I could run Nautilus 'nicely' but I don't want to make changes which would compromise other aspects of the system. It would also be pleasant, for a change, not to have to read a couple of telephone directories of technical documentation in order to resolve the problem myself. This must be a general problem and, in my view, something which seriously compromises the usefulness of Ubuntu given the sizes of contemporary drives and files.
The i7 I'm using at the moment has 8 cores non of which go over 15% usage while the copy is progressing despite the OS being effectively frozen for long periods.Environment:Intel Core i7-2600 @ 3.40GHz; 16GB RAM; Natty (11.04) fully updated as at 29th July 2011; Kernel 2.6.38-10-generic, GNOME 2.32.1.; Primary drive has 563.9GiB free space, Running in Ubuntu 'Classic' (no effects) mode

This is not the common problem that's on the stickied thread. I'm able to connect to my wireless network perfectly. I switch between Windows to game and Linux for desktop, coding, and hosting, so I can tell it has something to do with ubuntu 10.10. When I'm connected to my wireless network, at random times, my internet begins to slowdown, then I get disconnected from the internet, but the taskbar says I'm connected. This problem only happens in ubuntu and not Windows for some strange reason.
The applications that are usually open do not cause it, because it still does it even though I have little applications open (Google Chrome, gedit). When I'm on Teamspeak 3, I notice my ping rises to the 1000s randomly, and I get disconnected. Once again that only happens on Ubuntu.
I'm running 32-bit Debian Squeeze (2.6.32-5-686) on an old IBM TinkCentre piece-meal system that runs great otherwise. I have a LITEON iHAS424 Burner attached. As soon as I insert any disk (CD, DVD, Blank, Commercial, etc.) the system either locks up entirely or crawls to a near stop. The drive is about 3-4 months old and I've experienced the problem a couple of times in the past but just about every time I try to use it lately. The CD/DVD drive seems to work fine on other systems, but I haven't had the luxury of leaving in for any length of time to be 100% sure.
I have been able to pull out of the problem in the past by opening up the case and disconnecting/reconnecting both ends of the drive cable, but this doesn't always work and never "feels right" as a fix.Here is what I think are the significant portions of my messages log file:Quote:

I recently added an external hard drive through a IEEE 1394 interface. I'm finding that during large file transfers the system slows to a crawl. It's still running: routing for example seems fine. But running applications are pretty much unusable: Apache is unusably slow, SSH login is very slow, etc. Currently I'm using the IEEE 1394 drivers from Axel's ATRpms but I'm pretty sure I saw this with the default kernel IEEE 1394 drivers too.
View 4 Replies View RelatedI'm running a Geforce FX 5900 Ultra with nvidias 173.14.27 driver. I'm running slackware 13.1 with kernel 2.6.35.5.
I get a horrible slowdown which is noticeable in emulators such as bsnes and kega fusion. I also think it's responsible for other issues that involve zsnes flickering like mad and hanging. Zsnes will actually crash if I select any filter plugins with opengl output modes.
Kega Fusion slows down to a crawl (we're talking 10 fps) immediately before loading a rom. Playing a rom makes it even slower.
Bsnes has the same kinda slowdown as kega fusion (even worse since it's so cpu intensive) when I activate scanlines or any type of output filter with opengl. Otherwise with no filters and just plain opengl it seems to run fast like it should...
Gens-GS doesn't seem to enable any filters in fullscreen mode... They work however in windowed mode with no slowdown issues...
I've compiled and installed SDL 1.3 from hg repository, then recompiled bsnes just to test it with newer SDL. Unfortunately the problem persists even with a newer SDL version which thankfully for me means I can revert to the older stock SDL without having to recompile everything else haha!
It's funny because I thought these issues were related to the emulators and not the video card drivers. I had these issues for a couple years running ubuntu and trying other distros. When I installed Slackware 13.1 I decided to try my Radeon 9700 pro and kega fusion no longer had this slowdown issue! I switched back to my Geforce and installed nvidia's drivers and immediately had slowdown issues... I'm gonna switch back to the radeon card and test the other emulators but otherwise it'd be nice to know if there's a solution to this issue...
Ok I installed my radeon card: nvidia-installer --uninstall, then updated xf86-video-ati from 6.13.0 to 6.13.2. Even though kega fusion runs fine I get even worse problems with everything else! LOL so I'm going back to my geforce card.
I'm new to Linux, so I decided to try using Wubi to get started. THe problem is, when it finished installing 10.04, I got this message: OSError: [Errno 13] Permission denied: u'C:\ubuntu\install\ubuntu-10.04-desktop-amd64.iso' Is there any way around this? It might just be that overly restrictive thing called Vista (which I have the bad luck to be using). I was considering getting a USB drive for Ubuntu anyway..

What is the difference between the Ubuntu Installer for windows and the Ubuntu CD image? If I use the ubuntu installer for windows, does it have the capability to partition my drive, will it enable to share files with windows etc or is it just a way not to have to burn a CD. Just curious, the exact details of the installation files were not made clear on the website. Note: Windows Version: XP, 32bit, SP3. I have not partitioned anything yet.

I'm currently running off of my live-cd, and after spending 4 hours of my life trying to fix this myself, i figured someone out here has to know how to help me. Basically, i wanted to try linux, then liked it enough to decide to put on one of my usb-drives (320g adata nobility NH92), and i couldn't get it to boot anything but windows w/o the live-cd, which would then boot the live-cd, lol, in other words, i couldn't get it to boot at all from the external, even though i had changed the setting in my bios to boot from usb first, and tried manually selecting boot from usb and all that fun stuff.
Sooo... eventually i decided it might be a problem with the bootloader, and while i'm not exactly sure at this point what i have done to my computer, all i can successfully boot is the live cd. When I try to boot w/o the live cd, whether i try to boot from my internal (windows) drive, or external, all i get is a device not found error.I think i could fix it if i had windows recovery cd's (i'm running xp, btw), or installation cds, but... unfortunately, they died in a terrible accident. So i have no cd's at all for windows. :/
I have been running Ubuntu 10.04 under Windows 7 (Is this call WUBI?) without any problems for a while. My other machines only run Ubuntu (9.04 & 10.04).

After going through the successful installation and then rebooting, I am getting the following error message once I select 'Ubuntu' in the boot up menu right after the BIOS screen: Booting ' Ubuntu 10.10, kernel 2.6.35-25-generic'

I'm wondering if this is even possible. I've searched high and low and have yet to find and answer to this particular setup.
The setup:
Router is in another building.
Desktop connected by WiFi
Laptop connected by WiFi
Both the Desktop and the Laptop are in the same building together. About 5' apart.
SSH server is setup on Desktop
FreeNX client is setup on Laptop
So they can connect just fine via WiFi for remote desktop control of the Desktop from the Laptop (so SSH and FreeNX are working).Is it possible to connect the 2 pc's directly to each other by Ethernet cable AND transfer files between them by Ethernet while still being connected to the Internet by WiFi on them both?Or would the WiFi have to be disabled while using the Ethernet connection?Neither has a Gigabit Ethernet NIC so I know it would at least require a crossover cable or another router to connect the 2 by Ethernet cable.The idea behind all this is to be able to transfer files between computers quickly by Ethernet while the computers are still busy doing other things on the Internet by WiFi.
I've been trying to find what would be the lightest ubuntu or ubuntu based distribution, I have an older PC I'd like to get up and running again, and would prefer something that works pretty quickly on it (for basic web browsing and other things) the specs are:
AMD Duron 900Mhz, 384MB RAM, 40GB HDD, Geforce FX 5200 128MB agp.

View 7 Replies View RelatedThe scenario is as follows - I will be moving across the country and my desktop will stay here powered and online, while I move with a laptop. I need a way to connect to the desktop for file streaming(music and movies) as well as using the virtual machines. I have thought about SSH and VNC.I need something failsafe. That's priority one. I won't be around to fix it if it breaks. I can set the computer to come on in the BIOS at a certain time if the power went out. But if I can get in remotely the whole setup is useless.SSH only provides terminal use, correct? So if I chose that route I would be able to access the computer via command line and play music and movies with mplayer and such, correct? But I would not be able to run the virtual machines? Because there will be no GUI, right?
I have been playing with Vinagre and Vino through the host and guest of a virtual machine and I cannot get it to connect. Is there a better application? x11vnc? I have forwarded port 5900 on the router and have upnp enabled. Got a better remote desktop suggestion?I would like to run this setup headless.(no monitor) I also would like to run it without a gpu if that is possible to make it more energy efficient.Both computers are 64 bits and will be running Ubuntu 10.10 and soon 11.04.Are these crappy ideas to begin with? Should I go another route to get my files and access the virtual machines?
After a reinstall of 10.10, I am able to turn on file sharing and so I set up a shared folder.
Windows Vista can see this folder but in my network place, there is only one icon, and it's a "Windows Network" icon. Upon clicking on that, I can see the local network, "Rompus Room".
When I click on Rompus Room, nothing happens for a while, then I get a message saying, "Opening "ROMPUS ROOM". Then I get the final message, "Unable to mount location", followed by, "Failed to retieve share list from server"
