I have updated ubuntu to 8.10 it is working fine, but it takes long time to start, I mean when I launch ubuntu it takes long time from the first creen where ubunu is shown to the starting

I've noticed that after installing video drivers, in my case the proprietary nvidia driver, that it does take a little bit longer. I think that's to be expected. Not entirely sure though. But when you say "very slow", what are you using as a metric? In other words, what are you comparing it against?

I have the same problem. Im talking 3-4 minutes of black screen before the Login prompt, then like 2 minutes of Brown screen untill desktop... Any suggestions?

It was working fine before the update to 8.10. Started up in under 1.5 minutes before.

The situation is that I have been running 8.10 for while there was no problem to start ubuntu, but I think it is 2 or 3 days ago I run update manager ever since it takes about 3-4 minutes for ubuntu to start.
help is needed

I have the same problem. It looks like my machine has hung on the loading screen. Stays like that for about a minute before continuing.

I've just upgraded from 8.04 to 8.10

My brother mentioned that he just upgraded his linux kernal on Suse and it failed to boot up. I wonder if theres a connection somewhere.

There is a similar thread here

This reported bug is the issue I am experiencing
