@Neojames: The ureadahead packages have been accepted into karmic-updates, you need to ensure that that is enabled in your apt sources list. (The PPA is empty at this time.)

@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

When I run apt-get dist-upgrade nothing happens!

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.

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

Don’t complain here, do it at:
it will:

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…??

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.

Sorry, the correct link (for the bootchart) is http://sites.google.com/site/cribari/linux .

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

http://sites.google.com/cribari/linux

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).

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…

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!******

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

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.

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

Mine seems to be slower after this tweak. I wonder if I can undo it.

By: Andrea

Andrea — Mon, 02 Nov 2009 07:48:02 +0000

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
