Ubuntu Tip :Improve your boot times with ubuntu boot in Karmic

Compare to earlier ubuntu versions karmic is much better in speed but if you still want to reduce your boot times use ubuntu boot Packages containing instrumentation to aid in boot performance work, and packages proposed to improve performance.
Note:- Install these packages with your own risk and this might break your system

At the moment this packages are available to only ubuntu 9.10 (karmic) users

Install Ubuntu Boot in Karmic

First you need to run the following command from your terminal to add sources list

sudo add-apt-repository ppa:ubuntu-boot/ppa

Now update the source list

sudo apt-get update

Install using the following command

sudo sudo apt-get dist-upgrade

or you can install linux,ureadahead packages

This will install all the required packages.

I hope after installing this your boot times would be much faster.

  1. tried using this tip
    getting this error
    $ sudo add-apt-repository ppa:ubuntu-boot/ppaExecuting: gpg –ignore-time-conflict –no-options –no-default-keyring –secret-keyring /etc/apt/secring.gpg –trustdb-name /etc/apt/trustdb.gpg –keyring /etc/apt/trusted.gpg –keyserver keyserver.ubuntu.com –recv 4537E18AF1840D5CA312AED257B0CE6D09827771

  2. Well, I dont know if this is such a good idea.. Installing a custom kernel with no info about it?

    You doesnt even mention that it is a kernel they are installing.

  3. You didn’t mention that a reboot is needed to create the pack file. The speedup should come with the second boot. 🙂

  4. My boot times went down from 40 seconds to 28 seconds on 9.10 netbook remix. Thanks for the huge improvement!

  5. Strangely, this seems to have increased my boot time from 39 to 43 seconds. This is on an Eee 1000 with 9.10.

  6. Unsurprisingly, the problem is between the keyboard and the chair. I ran an upgrade before a dist-upgrade, so the kernel didn’t build properly (or so I assume). Is there any way to fix this?

    BTW, I followed the instructions PROPERLY for my desktop and shaved off about 5 seconds. Not too shabby.

  7. Since doing this ureadahead crashes on boot and the problem cannot even be reported because the kernel is customized (by ubuntu-boot).

    I need suggestions on how to go back, please.

    Thank you

  8. this “trick” caused me to get kernel errors and now i have to reinstall ubuntu completely

  9. Andrea, Mark, You don’t have to reinstall the whole system.

    When grub comes up, hit esc to take you to the list of kernels, choose the prior one, and boot from there. Then comment out or delete this ppa, update your sources, and uninstall/downgrade the packages it installed (2, right?)

    sudo apt-get install –reinstall ureadahead linux

  10. Please help me, I foolishly followed these directions without fully understanding what was happening (i.e. kernel upgrade). Now when I start 9.10, i get no nautilus/desktop, no gnome-panel, no compiz-fusion, and all I can do is open terminal or other programs from gnome-do. If anyone knows how to reverse this install, please please let me know.

  11. I’m getting complete system freezes now when launching a game several days after doing this. I think I’ll revert too…

  12. I ended up reinstalling 9.10 from the cd, it kept most of my system settings, and everything is fine again. ******BE VERY CAREFUL ABOUT FOLLOWING THE DIRECTIONS IN THIS ARTICLE!! I HAD TO RE-INSTALL!******

  13. Works like a charm for me. Change from 49 to 25 Seconds… this is a word. Even if I think that boot-time isn’t THIS important…

  14. Thanks. My boot time went down to 33 secs. However, my login time (after gdm) is quite high:

    cold login: 51 secs
    warm login: 8 secs

    (warm login is when I logout and then login again.) My bootchart is at


    Is there anything I could try to reduce my cold login time? Thanks.

    PS. I am running Ubuntu 9.10 64 bits on a DELL D630 notebook (graphics card: intel).

  15. I think I should point out that this only works for a normal HDD and not a SSD. If you have a SSD then your boot times will increase which is probably what those people have who said they gained 5 or so seconds because some netbooks use a SSDs’. For some more tips to decrease Ubuntus’ boot time then look at my website.

  16. I boot a RAID0 array; my /home directory is on another disk.

    I tried this and my boot time went from ~26 seconds to ~34 seconds.

    I switched back: piece of cake!!.

    Here’s how: Went to Synaptic > Origin > ppa.launchpad.net/main and selected the three installed packages for uninstallation. Went just fine. Rebooted and back to ~26 second boot time.

    Query: Perhaps this is no good for SSD AND RAID0…??

  17. Just ignore the “it will” from my previvous message; it came by mistake when i copy-pasted the link.

  18. This knocked about 15 seconds off and now on a 4 yr old laptop total boot to a browser opening is 1min 15secs. I had to reboot TWICE before it settled down – after first boot I got rainbow coloured squares instead of the logon screen!
    I still don’t really understand why boot times have got worse with ustart, My 9.04 time was about 50 seconds to the 1min 15 secs mentioned above. I did an upgrade instead of clean install but I am on ext4 and grub ‘2’. I’ll wait till 10.04 and do a fresh install again I think.

  19. @Neojames – there are a few things you could do, try a normal “sudo apt-get upgrade” after a “sudo apt-get update” or you could just try using synaptic to upgrade for you or even it is already installed and you dont need to do any of these. try looking in synaptic for “ureadahead” and if it is there with a filled in box then you have already got it installed. good luck
