Ubuntu Installation :: 10.04 Upgrade - Slows Network ?
Jul 8, 2010
I upgraded to 10.04 from 9.10.
Network accesses are now dramatically slower.
I upgraded a copy of my previous 9.10 installation so I can still use 9.10.
Network does work with 10.04 but is extremely slow. Website loading is initially quite fast but then slows to a crawl. Second and third tabs appear to stall completely, waiting for the first tab to finish.
All of this works just fine under 9.04.

I've just added an extra 1GB of RAM memory to my laptop (HP 530). Now I have 2 GB. Everything runs great, except Compiz and 3D games. It looks like anything that's related to the graphics card now slows down. Rotating the cube lags badly, so does the Burn effect, and UrbanTerror is lagging too.
Before the upgrade, I had a Samsung 1GB SO-DIMM, 667 MHz. Then, I bought a Kingston 1GB SO-DIMM, 667 MHz too. When the laptop boots with either of the SO-DIMMs (only ONE GB at a time), everything runs smoothly, like before. But when I put both of them (regardless of the order in the sockets), my video card seems to slow down at nearly half of it's speed.
I haven't tried with Windows yet. Also, my graphics card has a dedicated memory of 256 MB, so there's no memory sharing between video and the RAM.
I just don't get it. Also, there are other people that seem to have slowdowns after upgrading the RAM, but usually the whole system is affected. For me, it's just the video. It actually boots faster with the 2 GB. Yet I found no clear solution to this.
Running Fedora 10 i686, on a 32-bit Intel Core Duo @2200 MHz, video card Intel 945GM Express, with 256 MB of dedicated memory. The swap partition is 2.8 GB in size.

I have a Actiontec m1000 modem from Qwest that seems to offer more speed to my brothers Windows PC then my Linux PC (same make and module) I checked the ping on all systems, and they all look fine. The only thing that seems different is the number of open sessions in the modem, Linux only uses 2, and Windows uses 80. My guess is that the modem uses sessions to control the bandwidth, but I don't know how to add sessions to Linux networking to compete for bandwidth. I did test in the same browser.

I have a newly installed Dell Optiplex 755 with Ubuntu 10.04 (64-bit) and I am having serious issues with network copying. Whenever I start rsync och scp with larger amounts of data my system becomes practically unresponsive (all types of apps grey out) until those processes are completed. Cpu stays at below 10% and I have lots of free memory and such .

A few months back I performed a routine aptitude upgrade on a Squeeze installation on a DELL Vostro desktop. My eth0 upload speed is now very bad although download speed is good. I suspect that it could be related to my other problem [URL] which was caused by the OS enabling noveau driver instead of the installed NVIDIA proprietary drivers.
dmesg says:
eth0: Tigon3 [partno(BCM57788) rev 577880001] (PCI Express) MAC address 00:26:2d:23:a0:a5
eth0: attached PHY driver [Broadcom BCM57780] (mii_bus:phy_address=300:01)
eth0: RXcsums[1] LinkChgREG[0] MIrq[0] ASF[0] TSOcap[1]
eth0: dma_rwctrl[76180000] dma_mask[64-bit]
Where do I start to troubleshoot?

Recently my boot time went from barely 2 minutes to more than 10.it goes to text from the splash logo and a line shows :"running dkms auto installation service for kernel 2.6.28-18-generic".And then each 3 or 4 minutes it shows a driver (for a total of 3) : nvidia, vboxdrv and other one related to vbox.I've scanned through syslog but I can't find anything related to this issue.

Installed Karmic or upgraded to it, and the Time Date in the upper right loses time now after upgrade to Karmic. Worked fine before upgrade so it is not hardware.

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz

I was using Karmic Koala on my Asus 1005HA and everything was working ok. After upgrading to Lucid Lynx I have no network access anymore.
Pinging to my router returns "Network is unreachable".

This is my fourth on-line upgrade from Gutsy (started with Dapper ...) all the previous one went without a hitch !
So I was pretty confident this afternoon upgrading my Lenovo laptop from 9.04 to 9.10.
At one point during the install, I got error messages and was offer to do a "Partial Install". I accepted, different things happened, rebooted. Update manager came on with again the partial update pop-up. Accepted it again, it downloaded more files, rebooted, partial upgrade window again but it failed immediately.
The network connection was gone, clicking on the network icon I got a message that the network manager is not running.
I cannot check or uncheck the "network unabled" choice.
However, 9.10 is running, slow and weird, but no network connection so I cannot try to finish the "partial upgrade"
Every time I reboot the Update manager pops up.
Trying to boot any previous version in "grub" fails right away saying it is unable to mount the drives ...
Is there a way to start the Network Manager from a terminal ?

I have a Dell D420 that I successfully upgraded to Ubuntu 10.10. Everything looks fine except there is no LAN or wireless working. I upgraded the BIOS to the latest version (A06) and there are no proprietary drivers listed under System/Administration/Additional drivers.
when I plug the LAN cable into the 420, the indicator cycles for a long time but eventually displays the red exclamation mark.

I was running Ubuntu 9.10 on my HP G70 laptop and did an upgrade using upgrade manager to Ubuntu 10.04.
Since I haven't been able to get wifi connection or wired working. The Network Manager applet is missing from the notification area and if I try to run nm-applet manually it says it is already running. I tried killing the process and then running it manually in the terminal and although the process appears to be running it is missing from the panel.
Booting into the live cd has the applet working fine so something in the upgrade process must have failed.
I tried changing the theme to see if it displays in other themes but had no luck.
I also tried to log into kde but kde seems to be broken. When I log into it after the splash screen all I get is a black screen with only my mouse pointer.

I keep getting the following msg as I try to upgrade from 10.04 -> 10.10 ... "Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report." I don't think any of the issues above apply - can anyone offer advice on how to get around or "force " the upgrade

I'm having a problem since my last upgrade from 11.2 to 11.3 (Gnome).
Before the upgrade NetworkManager would run just fine at start up, now I have to explicitly run the command from a console using the root user to start it.
(My problem is the same as this one, only in gnome instead of kde)

I hope somebody has a solution to this annoying situation: right after restart my system is very fast (at least for me), but after few days it slows down to the point when using it becomes a waste of time. As soon as I restart everything is OK. Usually I keep open 1-2 Open Office files, couple large PDFs, and some Firefox tabs at the same time, nothing special. No gaming/video on this rig, just basic internet and text processing. Here are my specs:
9.10 Karmic
Kernel Linux 2.6.31-22-generic
GNOME 2.28.1
Memory: 433.1 MiB
Processor: AMD Athlon 64 3200+
Am I wrong thinking that I have enough juice to keep these windows open? Maybe there is a way to tweak something?

Using ubuntu 10.10 64 bit, last few days my desktop is not stable. Everytime my system becomes very slowwwwwwwww after login (after 5 mins, after 2 mins very random), sometimes it takes a while even to get to login screen. I checked System Monitor when this happens, i don't see high cpu usage/memory usage. Only thing i see is, when i shutdown my machine, it giving few errors about Virtualbox.

About a week after installing 11.04, I started noticing that my computer basically locks up after leaving it for many hours. When I come back, I cant get any programs to respond. I click on Firefox and it takes about one minute for it to finally respond. If I try to launch Konsole, it locks up too. But suddenly all programs start responding at the same time, after about one minute.
This is very frustrating and I just feel the problem is zeitgeist. Of course I am not sure because I cant even run System Monitor to check the problem since I cant run any apps for about a minute. By the time I run System Monitor everything is working again.

I'm running Ubuntu in a virtualbox on a Windows 7 host. It works great - except after I start up the machine, the response to keystrokes and updating of the screen slows way down. It gets slower and slower until it is unbearable after about an hour. If I save the machine state and reload it, things work great again - so it sounds like a virtualbox problem, not an ubuntu problem. Do other people who run Ubuntu in a virtualbox see this behavior? Do other people who run virtualbox in Windows 7 see this?

After an online upgrade from f11 to f13, on rebooting the setup attempts to configure the wireless connection and fails with a not very illuminating "error configuring your network interface" notice, offering no option but to go back and try again, which of course fails again with the same error.
Wireless card is a D-link that works fine with the ath5k driver in f11.
how I can get out of this vicious cycle and proceed with booting the upgrade?

When ever I choose suspend to shutdown the hard drive slows and the picture on the screen freezes. The mouse and kb are disabled and the cpu fan keeps running. My hardware in in my sig below I have turned off automaitic updates straight after installing from disc as the last time I had it switched on after a few updates I got repeated ata drive read errors and the pc would freeze for a while being unable to read from the hdd. I have run wd diagnostics on the drive and it works fine. To fix this problem I did a clean install after messing round for 3 days and achieving nothing. I have an arch partition that works fine as well although I have not attempted to get suspend working with it. ( hal error) I have read a few thread on the net and tried entering the swap disks uuid into grub.

I have a Dell XPS M1530 which has 4GB of RAM and Nvidia graphics card. I have problem with Ubuntu 9.10 (had the same problem with previous version). If I change the desktop wallpaper from System > Preference > Appearance it seems to freeze everything momentarily (15-30 seconds). Then you see the jagged transition happen when wallpaper changes from current to new.
I tried with wallpaper-tray applet and it has the same affect. I have NVIDIA-Linux-x86-100.14.09-pkg1 installed for Nvidia and all the effects enabled. They don't run slow at all...Like when I move the window, the window frame is fluid and flows beautifully. Is there a way I can make the wallpaper issue go away? Or disable the transition effect on wallpaper change?

I ran Karmic until last week, and noticed that it seemed to be getting slower. I was hoping a clean install of Lucid would fix that. it's worse. If I leave my machine running for a few hours, something begins dragging down the performance to a crawl.
System Monitor sometimes won't come up - launches an empty grey window. Other times, System Monitor reports that gnome-system-monitor is consuming 86-96% CPU. This is a dual-core Dell e6500 laptop with 4 Gigs of RAM, it should fly. Any ideas on troubleshooting this?

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 have Ubuntu 10.10 running on a Dell Latitude E6500 notebook and am using the Broadcom STA wireless driver (just in passing, same happens on Mint 10).
My problem is this:
- when the computer is plugged into a power outlet, wireless works fine, but
- when the computer is running on battery, it hardly works at all: The network strength indicator item still shows the same connection strength but data are not transmitted anymore or only extremely slowly (google.com might 2 minutes to load).
The drop in performance literally happens 1 sec after unplugging it, and once the notebook is plugged into external power again, it resumes after a few seconds. (I have tested this with big downloads where you can see Firefox's or the Update Manager's download speeds.) The BIOS doesn't seem to have power saving settings that make that happen, and I haven't found any in Ubuntu.

I started unarchiving a RAR file that this several gigabytes big. The computer is now going really slow, it's almost frozen. Sometimes I can move the mouse a little, but that's it. The unarchiving process seems to have halted, so now all I can do is restart the system. I don't think I can unarchive this file in Linux.

I'd noticed the RAM-usage issue, in that at boot and without browsers running, it sits right around 50% memory usage in both desktop and laptop. Again, no problem there. What kills me is when I run Firefox and Chrome at the same time (which I often due for development reasons, and because I have various accounts set up in each). When that happens, RAM usage will push 85-90% or higher. If this were just caching I wouldn't care, but this actually causes the whole system to slow down. Tabbing between pages slows down, sometimes the whole desktop will freeze for a second or two, it can take up to 10 seconds to get the screen back from the screensaver, applications & menus are slow to respond, etc etc. Killing one of the browsers will knock RAM usage back down to 70% or so and the sluggishness stops. I could have an identical number of windows open (two browsers w/ several tabs, big GIMP image, multiple small apps in parallel).

While upgrading to a newer version of Ubuntu I noticed a warning saying that the installation/upgrade should not be interupted. Unfortunately though, during this process my computer froze up and I had to shut it down. Ubuntu no longer starts on my computer. I still have Windows though, which is what I'm using now.

I've got a Lenny system on a quad core system with 4GB of ram. Currently Linux www 2.6.26-2-amd64 #1 SMP Thu Nov 25 02:05:44 UTC 2010 x86_64
I've had it for a couple of years, and its been fine, very fast and reliable.
Lately, its got a problem: after its been running for a day or two, access using SSH, or TLS/HTTPS gets really slow. Painfully slow. A reboot returns the system to normal fast operation.
I can't think of anything that has changed, other than I got a new SSL cert and installed it.
The system is mostly a vanity domain server, with Apache HTTPD running a half dozen very low volume services. Its running bind9, mysql, and a few other things, nothing big, nothing that would load down a quad core with lots of ram. The disk is only 14% used.
