Really slow boot after 9.04 to 9.10 upgrade

Slow booting too (compared with the version 9.04)

Very similar issue regarding slow boot times.

Jaunty booted in 14 seconds. Since updating to Karmic, my boot time now comes in at around 1 minute 3 seconds.

Please be aware that in Jaunty, bootchart would only log until the gnome login started. In Karmic, bootchart logs until the gnome login starts, and then keeps logging for an additional 45 seconds.

This was changed to better represent the fact that the operating system has to keep loading after you login.

As a result of this change, the boot time given in the upper left hand corner is no longer the correct time it takes to boot your computer. To find the correct boot time, look at the top of the chart and see when the hard drive stops loading. That time is your total start time for the computer.

If you are unable to find a clear point for which the hard drive stops loading, then you may have to use a stopwatch.

The alternative to all of this is to subtract 45 seconds from the boot time given in the upper right hand corner. That way you can directly compare the numbers between Jaunty and Karmic.

The difference is more than can be explained by Fletch's bootchart explanation. I used to get a login prompt after 20 seconds, then launch apps and become productive after another 10 seconds. Now I wait over a minute for a login prompt, and a good 20 seconds more before I can do anything useful. Disappointing.

I am having the same problem using the Netbook Remix on my EEEPC 1005HA. I did not run any extensive measurements, but I would say that my boot times (from pressing the power button to viewing the login screen) has roughly doubled compared to 9.04.

The boot sequence as I view it on screen has also changed:

- I enter Grub (so far, so good)
- Time t=0: I press "enter" to exit Grub
- After exiting Grub, I now see the Ubuntu logo on screen for about 20 seconds. This is new behavior compared to 9.04. After these 10 seconds, I get a blank screen for another 10 seconds (with only what seems to be a text-based cursor on the top-left of my screen).
- Only after these 20+10 seconds, do I see the "normal" boot screen that looks like boot in under progress
- I head the drum sound about 3-4 seconds *before* the login screen appears.

I hope this helps!

For me it takes a very long time from gdm to the gnome-desktop... I think it is only a upgrade issue as I read in other forums that a fresh install runs smooth. But as long as UbuntuOne doesn't automatical saves my konfiguration and installation state, im to lazy to do this manually. ;)

I did a fresh install and it also boots very slowly.

On an Aspire One ZG5 with the stock 8GB SSD.

Under UNR 9.04 it took less than 1 minutes to cold boot and have Firefox Loaded.

Now with UNR 9.10, it take close to 2 minutes just to cold boot to the desktop.

I did two change to try to improve the perdormance, set the elevator=noop.
Modified in the fstab and put 0 instead of 1:

UUID=Xyz / ext4 errors=remount-ro 0 0

It didn't change much the boot time.

Attached bootchart, hope it help to find the issue.?field.comment=On an Aspire One ZG5 with the stock 8GB SSD.

Same problem here.
I just upgraded from jaunty. Now with 9.10 I first get the Ubuntu logo (guess for some reason Ubuntu now boots a bit like Vista). Then I get a text screen which waits for a very long time and after that I get the "normal" ubunto boot screen (with the kind of nightrider bar to tell you something is happening). After that screen, the logon screen takes a wile to display correctly.

Also, when I plug in an external HD, the system does not boot at all, but I had the same problem with Jaunty. I gues this is because I have installed (and run) Ubunto on an external drive.

So booting gets more and more frustrating when I upgrade (starting with Jaunty with the usb drive boot problem).

Of course, when it has booted its a great OS.
