Ubuntu :: Udevd Takes 2.8 Times Longer Than It Should?
Aug 20, 2011
Running 10.04.3 on my rig specs in signaturethis happened after i tried oracle virtulabox 4 trying to get unity in itbefore i installed it udevd took about 2-2.5 seconds now it takes 7 seconds (it takes less than 1 second in my virtualbox)i still could not get unity in it i reverted back to my 3.1.6 virtualbox and udevd is still slow BEFORE:AFTER:i have removed all the junk i could find left over from virtualbox 4 /etc/rc{0..6}.d/{K20vboxballoonctrl-service,K20vboxdrv,K20vboxweb-service,S20vboxdrv}/var/lib/update-rc.d/{vboxdrv,vboxweb-service,vboxballoonctrl-********* -> boards are apparently not letting the post that rightfrom what i have been able to find out about udev it it does stuff with kernel eventsis there a way i can clean up udev/few what it is doing and remove what ever junk got in it it appears to be timing out IMO i have been looking for a solution for over 24 hours at this point if i have to replace udev with a manual version so be it as long as i have a app that can generate itfor the record my virtual 10.04.3 boots faster then my main install on a ssd as a result of this and that is just sad a install can boot faster on a 80 Mbps than a 240Mbps drive i should be able to boot to the login in about 5 seconds after posti know 5 seconds is not much time but percentage wise it is about 50% of my boot time
I experience this since kde 4, but it never really was that bad because once in a while on updating kde I also deleted the .kde folder in my home-folder and everything was fast again.
But I haven't done this for a while now and kde take really long to load. Is there any folder to clean up there without deleting the whole .kde-folder and loosing all my settings again?
I have been having trouble with Ubuntu 11.04 when connecting to the Internet via Wireless Networking. It will connect, and has good speed once it connects, however it takes upward of 10 minutes and over 20 times of me clicking 'Connect'.
Is there a way to connect to a wireless network quicker? My network is unsecured and without a keyring. It is not only slow connecting to my network, but the network of other's.
Upgraded to 2.6.32-32-generic, it takes about 20 seconds after login at boot up; previous version only takes about 13 seconds. They are at the same environment and service status.(ubuntu 10.04)
I need show the number of process per user, and after the date of the oldest process per user also.
With "ps -eo user | sort -u" i get all users that are running any process. And with "ps U username | wc -l" i get the number of process that the user "username" is running.
But how can i merge both commands for do what i need? Like a FOR or something like that. There is any method of make a FOR using the list that i get with the first command?
And then for show the date of the oldest process.. with "ps U username | sort -k 4" (4 is TIME field) i can show the process of the user "username" sorting they by time. But how can i get the date of the process takes longer running?? I can get only the time, but no the date.
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 finally decided to updgrade from Hardy Heron to Lucid Lynx. for this i made a backup of my old install, then i couldnt find my Lucid CD so i used a Karmic one to partition my old ext3 to ext4. There were some errors but after trying a few times it worked. Installed Karmic, rebooted (worked fine), downloaded all updates - (did NOT reboot to let updates take effect) and upgraded to Lucid.
Everything went fine so far. Now when i try to boot into Lucid the system hangs, i've also got a windowsXP partition on there so i tried booting that, first grub tells me Error 29: Disk write error then trying again windows seems to boot but it takes much longer than it should and seems to hang.
Then i tried Karmic and Lucid LiveCD (which i found in the meantime) none of the LiveCDs make it to boot after about 20 minutes. (previously they worked fine)looking at the errors it seems to be something about the harddrive. Why the harddrive would stop the LiveCD booting is a mystery to me but the same messages appear when i select Recovery from the Grub menu so i guess the problem is related.
i was just wondering because i.m changing the login noise, and i.ve gotten everything setup...but i.m reading that ubuntu only recognizes it if it is about 10 seconds long, and the noise i.m using is about 4 seconds...
I have a Raid0 setup (see below for details) connected to the ICH10R raid chip on my Gigabyte EX58-UD4P motherboard. On every second og third boot I get the following error:
Code: udevd-work[157]: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory udevd-work[179]: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory The system halts for a seconds or two and then boots on like nothing has happend.
My setup is as follows:
Two 500gb discs in Raid0 on the ICH10R. The first partition 100 mb is a Windows 7 system partition (gaming etc.) and then a 300gb partition for the actual Windos install. Then Ubuntu 10.10 with /, /home, /swap and then five data partitions. Grub is on the Windows system partition.
Ubuntu 10.10 x64 installed via USB. No problems during install. Besides that I have 2x300gb dics on the Gigabyte built in raid controller. Installed with a Hackintos setup using Mac software raid.My fstab looks like this:
Code: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5).
We have a problem with udevd process. It keeps going increasing slowly up to 100% cpu and the only way we can sort it out is by stopping udev and starting it back up again or rebooting the server... :/ see below info on server, it is used to purely run PHP, mysql and other static content is being served from other servers:
Just completed the online update of Ubuntu 10 -> 10.04 LTS. One problem, on boot keeps trying to mount "UDEVD-WORK...." (rest of line disappears before I can write down), which fails because it does not exist.
I am seeing a udev error message on booting that I have not seen before with LInux and which I cannot interpret. My Suse 11.4-KDE installation is fairly new. My system is a System 76 PanP4 Pangolin that originally ran Ubuntu.Uname -a returns: Linux linux-zcga 2.6.37.6-0.5-desktop #1 SMP PREEMPT 2011-04-25 21:48:33 +0200 x86_64 x86_64 x86_64 GNU/Linux. My video is a Geforce 9300M with an nVidia driver.A Google search turns up the fact that similar error messages have been reported with Fedora, Ubuntu, Meego and Gentoo. These frequently have had something to do with sound and in at least one case the advised correction was to reinstall udev. I can see where bugs were filed but with no clear response. Some of these go back several years, the most recent is within the last few months. I did not see a posting that involved Suse.
1.Can someone tell me what these error messages mean? 2.Does this pose a problem?Everything seems to work normally on my system once I am through the boot process. 3.If this is a problem how does one fix it?
I haven't updated my centos box for almost about a year, my theory is if it ain't broke don't fix it.These last two weeks I've been replacing hardware, a motherboard, memory, processor, and a hard-disk. Everything worked fine with the current 2.6.18-128.1.10, but I decided that I should upgrade to the latest along with all the new packages. But in doing so I would need to recompile the driver module for the raid controllers, rr1740. So I recompiled them using the 2.6.18-164.1 build while I was in kernel 128. When I was done, I restarted the machine and when it booted to the new 164 kernel, it came back very long error messages but here's what I can remember off the top of my head.
I need some advice on how to troubleshoot a booting problem. On my F12 installation, kernel 2.6.31.12-174 (and prior) all work fine. Kernels 2.6.32.x all stop booting at "starting udevd" -- even the cursor on the console stops blinking. My system is P4 2.4 GHz with 2 GB RAM on Asus P4PE -- old, but pretty generic.
I am running Centos 5.3. I ran no updates, performed no installs, nor changed any configuration immediately prior to this issue. My problem is this: when I run the command startx (default runlevel 3), it is a long time (5-10 minutes) before Gnome startx, and once it does start applications will not run. Also, when I try to use sudo (from any environment, even ssh), it is a long time (5-10) before the command is executed.
I cannot say for sure, but it seems like this is an intermittent problem. Sometimes X takes a long time to start, but once it starts it will launch programs. Sometimes X takes a long time to launch, but once it starts it will only launch certain programs. Though presently X always takes a long time to start, and I cannot successfully launch any programs.
A while back a had a similar problem to this (x taking long time to start, sudo taking long time to execute) and it ended up being a DNS problem. Unfortunately, I cannot remember exactly what it was and I stupidly did not document it. Maybe this is also DNS related, I don't know.
I don't know what log files to look at for problems with X, Gnome, and sudo taking a long time to start.
I have a dual boot system using ubuntu, 7, and vista. I want to get rid of vista. I already tried to use my recovery discs but they never give me an option as per what to partition and what not to, and it comes with vista and seven. I really need the space and can't currently afford a portable hard drive.
after downloading all the upgrade packages my install has taken about 8 hrs to complete, Im using a 3.0 ghz P4 with 1.5 gb of RAM on a 74 GB Raptor hard disk,
I'm running 9.1 and Firefox 3.5.7 with a few addons (better privacy, ghostery, cookieculler, adblock, personas) on a HP 8710p laptop with 4gb of ram.I use it to browse the internet at work, and I have it up for about 8-9 hours every day, during the course of the day I will open and close tons of tabs. At the end of the day when I'm getting ready to leave, I close out of firefox, and it takes one of my duo core processors all the way to 100% and sit at the top of my processes in my Conky for 5-10 minutes before it finally closes. I've been googling for a couple days and have yet to come up with anything,
I am having a problem with a slow wake up from the hibernate in karmic with gnome.My desktop has 2GB of ram and 4GB of swap.m doing standard hibernate from the menu.Hibernation takes 44s, which I can live with for now. But wake up measured from grub boot menu to unlock dialog takes 2m 47s. I think it's reasonable to expect it to take less than a minute.
I've been using lucid since the pre alpha and I don't know why but I think it kept getting slower and slower to me until I've noticed "Windows" for god's sakes starts up faster than lucid! I've looked for some suggestions but nothing paid off. I've made a boot chart for my boot. I've noticed mount.ntfs-3g is taking too much time but how to stop it. My fstab is
When printing web pages or PDF files in Ubuntu 10.04 to a network printer using CUPS, files are blown out to huge sizes - over 200Mb for a 30Mb PDF document and over 70Mb for a simple web page with 6 images and some text. Its holding up everyone else in our office who, through Windows XP are printing the same files in about a 20th of the time it takes Ubuntu+CUPS. I have tried printing directly to the printer, printing through the Win2003 PDC share, printing with LPR (which coincidentally generates a bit smaller ps file) and printing with Adobe Reader instead of evince
I have installed Ubuntu 9.10 on my PC ie AMD Athlon x64 with 15 GB for (root) partition and 2 gb for Swap Space,with 1.2 GB of RAM,but after the successful installation its not displaying the GRUB immediately, taking 90-270 seconds to display? What might be the reason.? I have windows XP on my pc,even for booting into Win XP, one needs the GRUB display, its taking almost 90-180 Seconds to display the GRUB(sometimes more than that). But this thing never used to happen in previous versions of Ubuntu? Why only for this specific Ubuntu 9.10?
I am running Ubuntu 10.04 Lucid, and it works perfectly.However, since last week (probably after some update), the gnome menu bar takes much longer to appear when I login. After it appears, it works just fine.To clarify, I turn on the system, login, the desktop background image and icons appear, and only after about 30 seconds the upper and lower gnome menu bars appear (a week ago all of it loaded almost instantly).
Title describes the problem rather well. After selecting Linux 2.6.23-22-generic 64-bit in the GRUB bootloader, I am staring at a black screen with a white flashing underscore for almost 2 minutes (usually between 1min40sec and 2min). The Linux kernel is loading here, and it's taking forever!
Once Plymouth starts it barely even manages to flash into view before it's done and I get to login, so bravo @ Canonical.
But seriously, I need that boot time cut down A LOT.
Since I'm assuming it has quite some relevance, here's all my installed programs: (So if you know any offenders you can point them out)
EDIT: I can see it also lists packages I've removed after installing them. Removed packages are listed as "deinstall" and are, obviously, NOT installed or functioning, but their config files remain I assume.
After I installed a new hard drive, when I booted up into Ubuntu, it would give me this error: "failed command: WRITE DMA". So I tried the workarounds and I guess it just covered the log with the Boot Splash, now it's taking a long time just to boot up.
I recently changed my computer so it would auto boot into Ubuntu, but if I hold down the shift key, I can bring up the GRUB menu so I can choose Windows in the rare times I use it[URL]Anyway, I noticed that when I did that, it actually took longer to boot. I timed it today and it took 45 seconds from the time I pressed the power button to get to the login screen! My friend uses Linux a lot and says even with Ubuntu (which he thinks is "too slow") it shouldn't take that long.
