Ubuntu :: Slow USB Throughput After Natty Update?
Jul 7, 2011
I accepted the latest Natty update about which I was notified a couple of days ago (I don't remember exactly). I don't remember a new kernel being pushed out, but for the record I'm on 2.6.38-8-generic right now. I'm trying to interact with a USB compact flash reader and I'm getting ridiculously low throughput (less than 1 MB per second). Before this latest upgrade, I don't remember this being a problem.
Better yet, does anybody know what might be wrong and what I might be able to do to fix this?

Having finally got Samba shares and printer shares working on my Lucid Lynx server, I've noticed that the throughput from/to those shares is very slow to what I was used to when I had those shares on a W2K server.Having Googled this problem, I noted that there was a known issue with this in Karmic (believe Brian Wu was looking at it). However, I don't see any results in Google as to this being a problem in Lucid.
I know ipv6 can cause a problem in this regard but having issued the command:
lsmod | grep inet6
I know that ipv6 is indeed disabled on my Lucid server. Any further information on whether the error reported in Karmic still applies in Lucid, and can this be addressed in any way?

I have a Acer Revo R3610 nettop on which I installed oS11.3. It has an Atheros AR5001 wireless network adaptor.I'm getting very bad latency and throughput on with this card. In comparison my Thinkpad with Intel card achieves at least 10 times the throughput from the same location. Also when I boot my wifi will come up authenticate and then a few seconds later disconnect and reconnect. I've tried updating the kernel to 2.6.35 as one of the fixes was to improve the performance of the ath5k driver. I'm using wpa2 authentication.
Here are some details:
Code:
mediacentre:~ # /sbin/lspci -nnk
00:00.0 Host bridge [0600]: nVidia Corporation MCP79 Host Bridge [10de:0a82] (rev b1)
Subsystem: Acer Incorporated [ALI] Device [1025:0222]
[code]....
Is there anything else I paste that will help determine the cause of the bad throughput. Browsing the web or copying files across the network is bordering unusable.

Update Manager is inviting me to update from my Maverick Meerkat to Natty. Is this a good idea?

I am dual booting natty and linux mint debian edition. I have noticed in LMDE compiz is far, far, far, far smoother. In natty scrolling, resizing, and animations are all noticeably laggier. In LMDE I can use the normal resize with no problem, in natty its so laggy I need to use rectangle or stretch. Animations are also glitchy (fade animations have white flicker) In lmde there are no visual hiccups.
I am using the same driver and kernel in LMDE, the major difference is LMDE has a much older compiz (0.8.4, before the compiz++ rewrite I believe.) Does anyone know why the newer compiz in natty is so much slower? Does anyone else expereince this? my video card is an hd2600 using the cat 11.4 driver, but I experience these same issues with the oss driver.

Since my upgrade to 11.04, ubuntu has been running real slow. When I click on the firefox icon on the side bar, it literally takes over 3 seconds to start opening up. And the same thing goes for folders. Is there something I need to tweak to fix this? And my computer is pretty fast on its own, vista runs very fast on it if that says something.

I have two versions of Natty that I'm running on my EeePC 900. Both are clean installs. As they're both installed on removable flash drives, I expect a certain degree of sluggishness. One installation is the full version with Unity. It boots in about 25 seconds or so, which is slower than Lucid on the same machine, but not too bad.
The other installation was a command-line install with Openbox and GDM for logging in. You'd think this would be quicker, but it's taking a full minute to boot. When it gets to the GDM login screen, I can't see the mouse pointer. If I move the mouse into the lower right-hand corner, I can see the invisible pointer hover over the shutdown button and then I can select it. Alternatively, if I press return (to select my login) and then move the mouse vigorously, a pointer will eventually appear, but it's a large X and not the standard pointer.

I've seen this issue mentioned before, but it appears their cause was different than mine.Here is a snippet of my dmesg log:
Code:
[ 2.797917] cdrom: Uniform CD-ROM driver Revision: 3.20
[ 2.798077] sr 3:0:0:0: Attached scsi CD-ROM sr0
[ 2.798149] sr 3:0:0:0: Attached scsi generic sg1 type 5[code]....
I'm not exactly sure what that is or why that's causing it to take so long to do.

I had a dual install of Windows and Ubuntu working for a good week, then I reinstalled Ubuntu, completely wiping the machine. My connection is greatly reduced--updates take hours to install, but internet surfs okay.
Code:
mieum@mieum-1000HE:~$ sudo ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:24:8c:29:5e:4b
inet addr:59.17.55.227 Bcast:59.17.55.255 Mask:255.255.255.224

After several upgrades (from 8.xx) I noticed Gnome terminal took about 4 seconds to open an window and another 4 seconds to give me a prompt. This is excruciating when blasting out CLI in dozens of terminals ssh'd into dozens of machines. Tabs were no different.
Fix was: Comment out anything in ~/.bashrc that references xterm. BOOM less than 1s total to prompt.
If it's faster than I can get my mouse hand back to the keyboard to start blasting CLI, it's good enough

After updating to kubuntu 11.04 natty, I have a problem with my internet-connection. The problem happens when I use VoIP-Software like Skype or Twinkle and also when using ktorrent.
When using the mentioned software, after 30-90 seconds the internet gets very slow. In f.e. skype, I can hear the one I phoned very badly.
I use kubuntu on a desktop-PC with a Linksys USB-Wlan-Stick. Detailed information is below.
Code:
uname -a

After doing a wubi install of 11.04 onto my hp g56-116a because of it having all 4 primary partitions in use, natty seems to be running abnormally slow Not throughout, but there's major slowdowns when doing something like opening a new browser window or similar task.
Sometimes it will just spontaneously log out. The slowdowns are so bad the mouse cursor will become completely unresponsive/laggy for 20-25 seconds. My laptop has 4GB RAM and an intel celeron t3500 cpu, which zips windows 7 along speedily, but its running this install a lot slower than my old laptop ran in,with 2GB RAM and a slightly slower processor.

I just upgraded to 11.04 from 10.10. I have a Radeon 6450 with 1GB of video RAM which should give me pretty good performance, but I'm only getting a measly 60 fps with the new ATI diver (11.4). I installed like this, making sure I'd removed the open source driver:sh ati-driver-installer-11-4-x86.x86_64.run --buildpkg Ubuntu/nattyThen installed the debs and ran an aticonfig --initial. The module builds and installs fine:tnugent@translocon:~$ fglrxinfo display: :0.0 screen: 0OpenGL vendor string: ATI Technologies Inc.OpenGL renderer string: AMD Radeon HD 6450OpenGL version string: 4.1.10666 Compatibility Profile ContextBut this is not good:
tnugent@translocon:~$ fgl_glxgears
Using GLX_SGIX_pbuffer
274 frames in 5.0 seconds = 54.800 FPS

After updating to natty I cannot compile any Gtk+ code, no matter what I do I get linker errors. This is not a problem with the way I'm building it, I'm familiar with the correct usage of pkg-config.
Even this code will fail to link:
Code:
#include <gtk/gtk.h>
int main(int argc, char** argv) {
gkt_init(&argc, &argv);
gtk_main(); }
(Compiled with the standard commands to compile Gtk+ stuff)
I always get the following output:
Code:
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_source_get_time'
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_get_monotonic_time'

I have an 10.10 Maverick Ubuntu, and I've tried to update it to Natty version, but when I try it says to I check my connection with Internet and then close the update app, but my connection is fine, I think this could be something related to the host, since when I try to use sudo or play Frets on Fire it says that they "couldn't resolve the host".

Since I have updated last night from maverick to the latest beta of natty narwal, I'm having a lot of trouble getting Nautilus (desktop included) to work.
It seems to crash since the very start as when I turn off the computer, the message of "force exit" appears.

I have to manage a publicly accessible computer, and people know the password and are willing to click just anything, that pops up and has a "yes"/"ok"/"i agree" button on it, just to make the message disappear. (yes, I hate their ignorance ...) As long as they can use the net, that is all they care about...
My question is, can I still get updates for Maverick without being prompted for upgrade to Natty? Also I would like to remove the button from Update Manager. Is there a simple way to do that?

Currently I am trying to update my drivers in 11.04 on a dell inspiron mini.
I do not believe it is a pure dell problem, as my regular dell xps running 10.10 has been having to problems updating.
I go into additional drivers and start having it search but it gets stuck and states:
Downloading package indexes failed, please check your network status. Most drivers will not be available.
Does this mean the servers are just really busy? Or do I have a problem somewhere on my end?

I was messing around with some stuff I probably shouldn't have when trying to get my Intel graphics card working better (that's another problem completely). Now the update manager has ceased to work. Every time I try to use it this error pops up:
Quote:
Could not initialize the package information
An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:

When I run the update manager in XUbuntu (natty/11:04) it does not show its progress while installing the upgrades.
After clicking on "install updates" and authenticating, there used to be a popup window with a progress bar and an option to show "details" but these appear to have disappeared in the last few days.
I don't recall switching these features off and there are no settings to restore them, available within the GUI. Is there another way of restoring this functionality?
If not, is a reinstall the way to go? If so what package(s) need re-installing? And in-case it is a configuration script, what files in my home directory need deleting to ensure a clean reinstall.

I keep getting a very frustrating error after reinstalling 11.04 on a 64-bit server:
Code:
W: Failed to fetch gzip:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_natty_universe_source_Sources Hash Sum mismatch
which follow
Code:
bzip2: Data integrity error when decompressing.
[Code]...
I originally installed 11.04 on this system with the same disk so I'm confused as to what is happening. I have tried using different CD's and even installed of a USB. The memory test of the installer came back okay. The box has two PCI NICs that are recognized and functioning. The only package I have installed is openssh as this is a headless box. What makes this even more odd is that I have a newly installed 32-bit 11.04 server with the same procedure on the same network and it does just fine.
I hope I have been thorough enough in my search and investigation that someone can point me in the right direction. After reinstalling 3 times I am at a loss and I know 11.04 can run on my box without problem (as it did before the reinstall).Tonight I'm going to reinstall with the built in interface unplugged and the two NICs removed, I'm hoping this will prevent apt from bricking itself during the install, which is the only think left I can think of. I suspect the issue has to do with the nic despite it appearing to function properly I am unable to uncompress the archives in question on, my workstation, when they are downloaded on the sever but can successfully uncompress the same files when downloaded on the workstation.
SOLUTION: I pulled both NIC's and enabled the integrated interface and it is all working. I wonder why they didn't work though...

I cannot get the update or software center to work now that I am running natty. When I try to update manager it says
"E:Encountered a section with no Package:
header, Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_natty_main_bina ry-i386_Packages,

I assume that the software center has something to do with this too...

I'm running Ubuntu 10.10 Maverick Meerkat and I'd like to know when does the update manager upgrade the system to Ubuntu 11.04 Natty Narwhal. I do not want it to do the upgrade too early,as this might cause problems.I heard they're going to release Natty by the end of April,when it passes the beta stage but it will take 3-4 months for the bugs to be fixed. Also,please answer my other thread,it has new posts: [URL]

When I first boot up. I get the GRUB command line. What happened to the boot menu? And I can boot up into my Windows partition just fine. But when I try the other partitions i get "Unknown file system" or when I try to boot into the other ntfs drive, I get "BOOTMBR missing", but yet it does not mean Windows, because i can boot that just fine. I can't find my Ubuntu partition. How can I get the GRUB boot menu back?

I upgraded from Meerkat to Narwhal. After all the files have been downloaded and installed it rebooted. Once it rebooted it went straight to the GRUB command line. After couple of hours of research, I ended up at
[URL]
My root was at (hd0,1). So therefore I put this in at the GRUB prompt.
set root=(hd0,1)
linux /vmlinuz root=/dev/sda1 ro
initrd /initrd.img
boot
I did what it said and it got me into Ubuntu. Nice! It asked me to: After successfully booting into the system the user should run sudo update-grub I did. Next it asked me to review (/boot/grub/grub.cfg). That's where it is hairy, my file has multiple root settings and with msdos settings. That doesn't seem normal.
