Ubuntu :: Modprobe, Framevuffer, Udevadm, And Blkid Causing Slow Bootup In Lucid?
Sep 1, 2010
my brother's computer is pretty slow, but was working fine with ubuntu karmic, but I decided to finally upgrade him to lucid the other day, and recently his bootups take, at worst, 10 minutes,when in karmic it took way less. It just sits on a blank screen (not even a blinking cursor)
His pc's specs are:
1.4 Ghz processor (single core)
on-board graphics (no graphics card)
two hdd's one 80GB and one 150GB (the 150GB is split into 3 partitions)
465.7MB of ram 4.1GB of swap
I've attached his bootchart and it seems that Modprobe, Framebuffer, udevadm, and blkid are taking the most time to load, but I dont really know, i'm new to linux. Also how do i disable bootchart now that iv'e used it. p.s Heres he same bootchart just in case the one attached gets shrunk by ubuntuforums [URL]..

I'm running Ubuntu 11.04 and I'm really new to linux. My problem is that whenever I try to browse a site I notice the website loads very slowly because it takes a long time to do lookups. I installed Ubuntu with an onboard NIC and later switched to a PCI NIC (Dlink DGE-530T). Although I disabled the onboard NIC in the BIOS, it doesn't help. Could this conflict in configuration be a problem? My download rates are fine, its just lookups that take really long ( upto ~ 10 seconds). I know the PCI network card is fine because when I jump to Windows 7, lookups are normal again (~ 300ms). At first I thought about installing the sk98lin drivers for the PCI NIC but I saw a couple of places where people have mentioned that the skge driver that comes along with the kernel is better.
I have tried a system wide as well as Firefox disable of IPv6. Here is my /etc/udev/rules.d/70-persistent-net.rules
Code:
# PCI device 0x1186:0x4b01 (skge)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:01:14:eb:39", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x10de:0x0373 (forcedeth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:3e:19:ed", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
The interface I want to use according to the listing above is the one with the MAC - 00:24:01:14:eb:39.
I tried removing one of the entries in the file above and rebooting but it still didn't work. Here is a look at my /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.10
gateway 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255

Up until recently have always been a gnome or xfce user, recently decided to try kubuntu. I like it, but its very slow to boot. I get a blank blue screen (same shade as grub) right after grub has finished its countdown and starts Kubuntu.

Why would this iptables cause this mail delivery error? I think it's to do with dns lookups not being routed properly... if remove the last rule, mail works fine.
ssh is also very slow to connect when the last rule is enabled.
postfix mail error:
Code:
Jan 24 11:32:18 xxxx postfix/smtp[15065]: 9F2162C519: to=<xxxxx@hotmail.com>, relay=none, delay=1005, delays=965/0.01/40/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=hotmail.com type=MX: Host not found, try again) iptables

When it DOES boot, it runs like a champ, and has no issues. However, it tends to freeze up on the boot at the BIOS screen, this issue was around when Windows was on it.

I know this has technically been posted but I think my situation is a bit different. People have been complaining that karmic is slower to boot. But from what I gather, it's only a few seconds extra due to an extra splash screen. I'm running Ubuntu Studio and mine takes like 5 minutes and is showing me 3 splash screens! 2 for regular Ubuntu and 1 for studio, which is the most sluggish of the three.
My computer is a Toshiba Satellite A75
2.8 ghz pentium M
1.5 gb ram
Radeon graphics
60gb hdd
EDIT: Also, recovering from hibernate takes a few min. Related?

I just installed Lucid over Karmic on my netbook, unfortunately I had a little removeable USB hard drive attached during the installation. now when I boot, it keeps looking for the little HD, and I have to press "S" to make it "skip." what can I do to tell Lucid that I seldom use this drive so please shut up about it every time I turn it on?

After running Ubuntu Netbook off a USB for a while, I decided to format completely and install Ubuntu as the main OS. Except now the bootup is incredibly slow. Once I start the computer it goes to a black screen that resembles the Terminal. I have to wait 5-10 mins to get it completely booted up. Again, if I run it off the Ubuntu USB over the installed Ubuntu, the USB one is much faster.

I've been running 10.04 (lucid, Kernel Linux 2.6.32-25-generic, GNOME 2.30.2) for about 3 or 4 months and everything has been great, until yesterday.
All of the sudden, bootup has started taking longer than usual and the panel at the top of the screen with "applications", "places", etc. doesn't appear until the machine has been running for at least 2 minutes.
Also- the mouse and keyboard (and my external hard drive), all of which are usb, do not respond until about 2 minutes after startup appears to have finished.
So, basically, here's what happens when I power the machine on:
1. Everything functions quickly, and as normal, until my desktop picture shows and the icons on it appear.
2. Whereas before I would have had mouse and keyboard use (and use of the top panel with applications, places, etc.) at this point, I don't have use of any of these.
3. So I just wait, without keyboard or mouse, etc. for about 2-3 min and all of the sudden the top panel emerges, the mouse and keyboards start working, and then the external hard drive appears.
4. As if this weren't annoying enough, after everything above starts to work, opening applications (e.g. firefox) takes a lot longer than it used to. Basically, starting any application after startup takes a long time the first time it's opened.
I don't understand why this is happening. Before this, startup was super fast, and everything was working great. I dont know how to check into recently loaded updates, but perhaps something got changed there that is causing the problem.
I haven't changed anything hardware related at all, so I don't imagine the change in performance is due to anything on that front, but I could be wrong.

I made a clean install of Ubunto 10.10 on my Compaq Presarion F700, nVida graphics, AMD Turion 64x2.Installation was fine.When I boot, it takes a lot of time, 5 minutes or more.Also, after the system loads I get those applet errors I've attached. Sometimes I get all the applet errors and sometimes it get few of them.I tried several configs of "GRUB_CMDLINE_LINUX_DEFAULT" but still no luck.

After upgrading from Ubuntu 9.10 to 10.4 the console output stops during bootup at various points (during init final scripts processing and when the tty1 auto login). This is a colinux environment but has nothing do with the problem as it is the same version of colinux kernel that works correctly with 9.10 but exhibits the problem with in version 10.4 Lucid.
when tty1 using mingetty auto logs in the .profile file starts the gnome-session (command: DISPLAY=$DISPLAY dbus-launch gnome-session &) and when the panel comes up the shutdown button is disabled when it should be enabled.
However, if during the bootup when the console output stops, I immediately toggle to virtual console 2 (tty2) and immediately toggle back to virtual console 1 (tty1) it restores the output to the console and when bootup completes the gnome panel has the shutdown button enabled as it should be. Some times when the console output stops it looks like a screen clear was issued and other times the lines remains an the screen. I added --noclear to the line that calls mingetty in /etc/init/tty1.conf but is has no effect.

My ubuntu server has 4 2TB disks attached im using udev on boot to mount the disks suddenly one partition of such a hd cant be mounted it seems that udev isnt recognizing the filesystem anymore, all other partitions work as expected using blkid i get a list excluding the failed partition the mount command either doesnt recognize the filesystem but if i mount using -t ext3 i can use it without problems fsck.ext3 doesnt find any errors.
So my question: what i could try to get it up and running again? not sure if the problems began since a power outage.

I just 0 & 1'd a pen drive, and now I dont see it in 'blkid' output. Is there a way to know where the device is on the system, so that I can format it with a filesystem?

I multiboot my Lucid with Win7 and any other Linux Distro (I frequently keep changing these, presently using or trying Fedora Lovelock).I have noticed that the time between Grub Menu display and Ubuntu Splash screen has increased by a good number of seconds. I have set my Grub to select my default OS (Lucid lynx) after 3 seconds and which it does. But after that a black screen with blinking _ is displayed for sometime before Ubuntu loads with its splash screen.
I wonder what caused this? It was not the case before when ubuntu splash appeared almost immediately after Grub menu.

Upgraded from Hardy where all worked fast and the only annoying bug was a total freeze every so often. So I thought it would be good to go to the next LTS version and see if it works better. However it is very slow starting up. bootchart reports 2:44 min compared to 40 sec for Hardy and that is only the start-up. Then the real drag begins after you enter your password. It's been up to 30 min!!! before the system became responsive and did not have a solid HDD light.
So my question is where do I start troubleshooting. I'll include the bootchart and dmesg log. What else is needed to tackle this issue? I'm really in a tizzy here, since it's my wives laptop and she is not as patient as I am, to put it mildly. Do I need to downgrade back to Hardy

I just did a fresh install of Lucid on my desktop. The boot background splash screen comes up very fast, but then it is about a 1 minute wait until the login prompt appears. Then once I enter my login credentials, GNOME loads up ASAP. It wasn't this slow before I reinstalled. Anyone know why this could be? Everything works.

I seem to have a problem with my mobile broadband connection. I have a huaweii e166 usb hsdpa modem. It is veeerrryy slow. It used to work fine in karmic a few days ago, used to get 800kbps (from whatismy.com), now in Lucid the speed test does not even finish sometimes, but if I open the system monitor it shows about 1kbps. Sometimes is gets slightly faster and I can browser a bit more, but then the speed goes down again, to barely useable. I have also setup the modem in xp and whatismy.com speedtest shows 900+kbps constantly. I did a clean install of lucid on my compaq presario cq60 laptop. I have disabled ipv6 and installed the usb-modeswitch_1.1.2-2_i386.deb and usb-modeswitch-data_20100127-1_all.beb but it is still very slow.

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 am trying to install ubuntu 11.04 to my laptop, currently I have 10.10 installed and working. When I try to boot the computer from USB for installation, I get (after waiting a few minutes):
[Code]...
I am currently using windows 7 and ubuntu as dual boot. I didnt have this problem when I was installing 10.10. I am not sure but I think I upgraded my BIOS after my 10.10 installation, so that might be related. I didnt change anything else related to hardware since.
I am not sure what other information I should provide, Also note that given error message might not be 100% correct as I have typed it from a photo.

I have installed Kubuntu Lucid on my Samsung NB30 netbook. Got everything working, but the disk access seems extremely slow and noisy. Whenever larger files are being processed (software installation), the disk makes a kind of rattling sound - looks like the head is moving back and forth between two or more locations. The disk seems o.k. so far - no io errors under Linux and Windows XP boots without problems.

A lot of people have the problem to find themselves with Lucid Lynx 10.04 and experience massive issues when connecting to wireless - me too. As a service, here some relevant links which promise relief:
[code]...
I tried all of them, and none reliably worked. Every solution which required re-association wtih the AP helped for some time, but nothing helped for long. First, don't let yourself fool by the disable IPv6 trap - while it is "enabled" it is acutally not used by Lucid! I have a clean install of Kubuntu 10.04 on an AMD64 Laptop with Broadcom STA driver: 03:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03) However I can reliably stabilize my connection for some time either by manually disabling WiFi with the hardware switch or disabling WiFi by software means and re-activating. This brings speed at par with Kubuntu 9.10 until some time. Can anybody confirm this behaviour?

When Lucid released, I upgrade the Karmic in my Thinkpad R61 using
Code:
One things that remains until today is that when I'm using latest kernel (right now 2.6.32-24), the compiz run very slow, make the whole desktop unusable. When compiz is killed and using metacity, the desktop is running in normal speed.
Fortunately I still had the Karmic kernel (2.6.31-20) and booting using this kernel, everything run normally.
I just wonder what cause the latest kernel make compiz become slow. Is there any leftover application that I had to uninstall (maybe it's like pulseaudio's problem above), or any missing library/application that I need to install?

Samba doesn't seem to disconnect on shutdown except by timing out, causing a loooong Lucid shutdown. (I can disconnect manually before shutdown by unmounting the Samba shares, and shutdown is then very fast.) Apparently Network Manager is somehow involved. I've installed a NM shutdown Samba script which works for the first user account, but not for the second user account (which was created and then put into the admin group).

Laptop: HP 6910p Wireless Card: BCM4312 NO issues with wireless in 8.10 (intrepid) - fwcutter driver. Performed clean install of 10.04 (lucid) onto a brand new hard drive (July 2010) - fwcutter driver. NO issues with wireless in 10.04 (lucid) until a few days ago, when. my laptop shutdown because the battery died and I safe-upgraded to 2.6.32-24-generic. Currently I have chronic wireless connectivity issues - slow to non-existent. Ping tests (ping -c6 google.com or ping -c6 4.2.2.1) sometimes reveal 0% loss, sometimes 100% loss, sometimes "unknown host" - within 5 minutes of each other. Regardless of ping results, web pages are consistently slow to load. Skype will also cut out from time to time as the wireless connection vacillates. I have a MacBook Pro which I am using as my (wireless and consistently well-connected) control - and from which I am currently forced to draft this note.

Since "upgrading" (ha!) to lucid I have had a number of problems that I am working my way through. The latest is accessing samba shares from a Win7 PC. It takes minutes to open the requested share from the Windows 7 PC. File transfers, once the directory is accessed, can be measured in bytes. It is an absolute trickle.
AFAIK the smb.conf is unchanged and, in any case, there is no problem accessing the shares from another linux PC.

Problem occured yesterday and has added 3 mins to my boot time. all i can say about it is that it occured after a yum update and then a crash while using wine. i navigated to the file but really cant say much about it. however the pci call there makes me wonder if it is related to the post below.
Starting udev:

I installed Ubuntu Netbook Edition 10.10 on my Eee PC 901 (the one that has 2 SSD's). It all went fine, and I ran the update manager straight after install and config. It installed the updates (all 198 of them!) without error. I was prompted to restart, so I did. I got the error "udevadm trigger is not permitted while udev is unconfigured". I found out that this error is well documented, and I followed the guide at [url](apparently it affects all variants, not just UNE).
It went O.K., until I tried the command "sudo chroot /media/newroot". I got the error that "cannot run command '/bind/bash': no such file or directory". What should I do?
I cannot boot into and earlier kernel (problem/current one is 2.6.35-23-generic) I can only fix it via live USB stick.
