Ubuntu :: Suddenly Boot Time Got Longer - With BootChart Results
Jun 30, 2010
The thing I love most about 10.04 has been the boot times. Now, sadly that is gone for me... Suddenly it takes longer to boot. With almost no new apps installed and I have a separate disk for music/videos and such. Also, removed most of startup-applications!
Before, when the ubuntu logo showed the dots didn't even complete a whole lap, and...I was in the desktop... Now it does a couple rounds before eventually getting to the desktop.
Nothing extremely slow, but still noticable!..
Created a bootchart, but i couldn't see anything extraordinary.. maybe you guys can?

My ubuntu(10.10) installation takes a relatively longer time (90 seconds) to boot. I think part of the problem might be related to an error message during boot related to usb drivers.
Code:
[2.717076] usb 4-1: new low speed USB device using ohci_hcd and address 2
[3.244051] usb 4-2: new full speed USB device using ohci_hcd and address 3
[12.029046] /build/buildd/linux-2.6.35/drivers/hid/usbhid/hid-core.c: usb_submit_urb(ctrl) failed
I have attached the relevant part of dmesg output also.

I have OpenSUSE 11.2. I removed bootchart and forgot to run mkinitrd. Now, right at the start of the boot process, I get boot/93-bootchart.sh: line 17: 462 Terminated stopinitrd 5
I Can't find any 93-bootchart.sh anywhere. Earlier I got an error message about non existing /sbin/bootchartd, but I just copied /bin/cat to /sbin/bootchartd using a GParted boot disk. I tried to use chroot with an OpenSUSE boot disk, but mkinitrd can't find the root device, which is there actually (/dev/sda5). How can I make my system boot again? now I managed to re-install the bootchart rpm, using OpenSUSE boot disk and chmod. The system starts again. But that annoying bootchart is still there. I will not try again to remove it. First I will try to figure out, how to disable it during the boot process.

I'm timing how long it takes to run a command foo. I'm looking to append the results from the time command to a file, and discard the results from the foo command. I tried the following, but it didn't do what I want:
$ time ./foo > /dev/null >> output_from_time_command.txt

I have no idea what happened, but as of around a week ago, I can no longer print in Ubuntu 10.04.
The printer is a Brother MFC-7440N connected to my LAN. I have never had a problem before printing to it from any of my computers, regardless of whether they were running Windows XP, Windows 7, or Ubuntu 9.10 or 10.04. I am still able to print from Windows 7, so I'm reasonably sure there's nothing wrong with the printer or network configuration.
But I can't get it to print at all from Ubuntu. I already tried reinstalling the drivers and re-setting it up in CUPS - no change. Every time I try to print a test page, the printer does nothing, and "Document Print Status" shows the job as eternally "Pending."
If I go to the CUPS printer page [url], the job status shows as "Paused - "Unable to locate printer 'MFC-7440N'!"
I don't know why CUPS thinks it can't locate the printer. When I was setting up the printer in CUPS, CUPS properly detected it on the network, no problem.
I can see the printer in the CUPS administration page, and even change settings. The one thing I cannot do is get it to actually print!
Like I said, the printer works fine through Windows, so I think this is an Ubuntu problem, not a printer problem.
When I open "System->Administration->Printing," there's an icon of the printer with a green-circle check mark, as if everything is OK. But if I right-click, the "Enabled" box is not checked. Checking it myself has no apparent effect.

My wired internet was working fine and dandy under Maverick until today. For no apparent reason, it stopped. The router works fine. All other computers are able to connect. I've tried using different cables with no luck. I have a Biostar A785G3 motherboard with an integrated Realtek RTL8111DL ethernet controller.
My problem sounds very similar to this guy's: [url]. But his strange solution didn't seem to work in my case.

I am having trouble with encryption/ decryption program. The program goes out and finds the file I want it to, encrypts it into a continuing series of a single repeated negative number, then generally decrypts(or should i say re-encrypts)it into a widely repeated character, different but same results every time.

I get the bootchart.tgz file to be created, but I am unable to convert it to a png file. I have tried several instructions on how to make this conversion, but none of them have worked. Here is the one listed on this forum:
after login to GUI open your browser and go to: Bootchart scroll down to Renderer Web Form and upload bootchart log tarball located in /var/log/bootchart.tgz leave PNG format nex press Render chart button. I do not see the location on the website listed, to upload a file.
The other methods I have tried entail using the terminal to convert the file, but I continue to get errors on a failed conversion, or the wrong commands.Is there by chance I do not have a certain software yet installed to make this conversion on my laptop. I have installed the minimal OpenSUSE 11.3.

I've installed Squeeze on my two machines and now I discover that the Gnome Time GUI no longer has the ability to control NTP. Did they move the NTP GUI somewhere else or did we go backwards on this one?

I am reading about jiffies in linux kernel. In one of the related example in the book Linux Device Driver, the author use
head -8 /proc/currentime
to print out some time information.
However this file is not present in my linux installation (kernel: 2.6.32-131.6.1.el6.x86_64). Why is it the case? Is it because the file path is no longer valid, or it is a distribution feature thing? It is not present in OSX too. What would be an equivalent in OSX?

I did a kernel upgrade in openSUSE 11.2 which caused bootchart to fill the root partition or so it would appear as when I rebooted I started getting messages on the console saying bootchartd could not write because the device was full.
Let me begin by describing my system:
Partition table:
fdisk -l /dev/sda
Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00083a53
Device Boot Start End Blocks Id System
/dev/sda1 1 2612 20980858+ 7 HPFS/NTFS
/dev/sda2 2613 15666 104856255 7 HPFS/NTFS
/dev/sda3 * 15667 15927 2096482+ 83 Linux
code....
As you can see from the partition table I have 2GB allocated for the / partition and according to the df command there is 0 free space but du -hx shows / is only using 405MB. What's happened to the almost 1.6GB that should be available?

One requirement of a project I am currently working on (for Maemo) is that the Qt application displays a QSplashScreen when it loads.
My issue is that the application is fairly small and I have written it to load components etc as they are required rather than at start-up. This has lead to quick start up times (which, in a perfect world is what we all strive for!)
How would I intentionally delay the start-up time so that the splash shows for longer?
I have investigated
Quote:
QTimer:: oneShot() (Space added to prevent smiley)
however, its prototype dictates that it be connected to a slot. I am running this QSplashScreen from inside main so this is neither needed nor feasible.
What is the best way to essentially do this:
Code:
Display Splash
Timer for 3 seconds
Close Splash
Display mainWindow
I do not want to use native system calls such as sleep() and would instead rather a Qt based solution.

Got a boot problem on a sony vaio with ubuntu 10.04. All was working fine, and now, suddenly, it can't boot anymore....
Sometime, I get
Error : hd0,2 Out of disk
Most of the time, I get

It looks like there is no disk in the machine. Yesterday, there was one... So I boot with a liveCD. and have a look with fdisk:
ubuntu@ubuntu:~$ sudo fdisk -lu
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors

With disk utility, I can find my swap partition 4Gb, my system partition (Ext4, 20Gb), and 476Gb of freespace.

I installed Ubuntu 10.10 a while back using Wubi. I have it installed alongside Windows XP. Just yesterday the power went out in my house while I was booted into Ubuntu. When I turned my computer back on I still have the option to select Ubuntu or Windows, but now when I select Ubuntu I get right into a grub prompt. Grub used to give me a list of kernals but now it just sits waiting for commands.

I own an HP Envy 14 [url]. Letting Ubuntu (or any Linux) attempt to boot into a Live CD without changing any parameters results in a black screen, but with everything else working (for Ubuntu, that means the login sound is played). I've discovered that putting nomodeset in the kernel line will allow me to get so far as a command line, but I can't startx from here (I get "Screen(s) found, but none have a usable configuration."). I think my issues have something to do with the dual/switchable graphics in my laptop.

I have (had) a dual boot computer;Win XP and Ubuntu 10.10 64 bit.I decided it was necessary to enlarge my Root and Home Partitions. Using the instructions http://ubuntuforums.org/showthread.p...ome+Partitions I successfully enlarged the partitions and restored 10.10 (I used the copy command suggested by Irony). However when I boot the computer it boots to Ubuntu but no longer gives me the option of going into XP(it is not listed in Grub menu). Is there a fairly straightforward way of getting XP back on the Grub menu so I can boot to XP again?

Somehow, the wife got her laptop into this situation yesterday. The Windows partition booted normally when selected from GRUB but os 11.3 would boot to a command line login and pretty much everything besides CTRL-D was useless as the root partition was ro.
I booted a live CD and found two a couple of strange things. First, the system clock was reset to the default date/time (2007-xx-xx). I reset that. Second, after correcting the time I ran fsck on the root and home partitions. Both went through with no errors reported but the 20GB root partition took a long,long time to complete while the 80GB home partition went pretty quickly. After doing the above, the system booted normally but both partitions reported running the transaction log as well as forcing fsck where I had just done that. My question is for future reference: how does the system react to a grossly incorrect date/time, especially where all the drive data reports being much later than the reported system time? Would this be the reason for what I saw? I have no idea how the wife managed to reset the system clock, even if the

My pc went kaput a while ago and I've been using my friends laptop for the mean time. The HDD is having issues so I've been running ubuntu 10.04 on a live 8gb flash with persistence. I got real comfortable with this and saved important data on the live usb.Earlier today the pc did not shutdown correctly. When I restarted, ubuntu started booting and even showed the 5 moving dot loading screen, then it suddenly stopped and displayed the following:Quote:

My mum has a computer that has a dual boot with Windows XP and Ubuntu 10.10. Well Ubuntu will not boot anymore, i just get a bunch of CLI output mentioning missing stuff. But she has really important data that she needs which is on the ubuntu partition. I have tried using Ubuntu & Knoppix live CD's the mount the partition and copy the data to her external HDD. On Ubuntu it couldn't mount, it just kept trying and trying forever. On Knoppix it just gave me a heap of CLI output that I have no clue what it means. How can I save all her data? Is there a program that can sav the data, or what is the best way?

I recently switched from fedora 14 to 15. Today my computer suddenly shut down during an update, as I thought it overheated I decided to clean the cooling system and reapply thermal paste. However, now the system won't boot anymore ("kernel panic - not syncing : VFS: unable to mount root FS on unknown-block").
I would like to either solve this booting problem, or mount the fedora 15 filesystem and recover some files. Whichever is easier.
I have another drive with fedora 14 (antec below) which boots fine:
