I installed Kubuntu 10.4 (which runs great) a couple days ago but when I shut down it goes to the Kubutu shutdown screen and freezes. I still need to run updates which may fix the issue if not any suggestions. Thanks

Hi -

I'd be curious if a command line "sudo shutdown -h now" worked (even if the standard GUI "shutoff" button didn't)...

Thanks it worked.

I don't know if this will help or not, but I have found these points in Ubuntu, which may be related to what you see in Kubuntu:

1. If there is something else logged in, maybe on a text console, or via ssh from somewhere, or under screen somewhere, doing shutdown from the menu will only result in a logout. Since screen will leave things logged in even if the local window/console closes, even if screen is currently connected from local to local, it can create this impact.

2. If there is no net access or at least no DNS server access at time of shutdown from the menu, it will take a while to complete the shutdown, maybe 3 to 6 minutes.

I don't think I would change point #1. One can get around it via the command "shutdown" under sudo/root privilege if they must. Point #2 might be worth investigating (something is looking up something that during shutdown should not really be done, especially if the cause is to reset a network, etc).
