Can't turn off the computer after upgrade to 11.10

[Jarks]

Kubuntu 11.10 on notebook HP ProBook 4525s:

Hi,
after upgrade 11.04 -> 11.10 I can't turn the computer off. When I click on shutdown button, KDE disappears then the splash shows up and stays forever. I have to use the power off switch. What's wrong?

Thanks.

Can you shut down with the

shutdown

command? If not post the error message.

For now open a terminal and use these until this gets figured out for you.

sudo shutdown -h now

above for shutdown

sudo shutdown -r now

above for reboot

Thanks, but I can't.
I can switch from the splashscreen to the console (CTRL+ALT+F1) but I can't write anything. The keyboard doesn't work.

Well... can't you just use konsole or xterm?

Nope it's the same. But I've found the problem by hitting ESC on splashscreen. The last message there was something about umounting NFS volume. So I went to /etc/fstab, removed lines of connection to my home computer and shutting down works again. It's weird because I had no problems in 11.04.

there was this record In fstab:

# homecomp.local:/mnt/multimedia /mnt/homecomp-multimedia   nfs    rsize=8192,wsize=8192,timeo=14,intr,rw,users    0    0
