10.04 freezes while shutdown

[gljones]

Hi all, I am a very big fan of ubuntu 9.10 as it works perfectly on my Acer Travelmate 220 laptop, I couldent wait to upgrade to 10.04. However I am having problems after upgrading.

Problem one. when booting its showing a message about acer-wmi.

Problem sorted thanks to above link.

Problem two - The most annoying one.

Computer freezes when shuting down, I have to manually switch my laptop off. Sometimes it will shut-down OK but the majority of times the laptop freezes.

Also firefox (3.6.2) is much slower than 9.10

Please can someone help. I am really considering reinstalling 9.10 which worked like a dream.

I also have the same problem while shutting down in both ubuntu and kubunto 10.04. It only happens to me when I install the nvidia hardware drivers.

Do either of you see the caps and scroll lock lights blinking when it's stuck?

I have a hp envy and have the same problem and my caps lock some of the times start flashing.

Same here.
10.04 quite often freezes during shutdown.
Running on AMD64 with Nvidia drivers.

I get a freeze on shutdown or restart also. No blinking lights, just Ubuntu with some periods underneath it, hanging. This is on a Dell Latitude D630 laptop using the nvidia-current drivers.

one way to solve my "freeze on shutdown" was to use reboot and press the poweroffbutton at the boot menu.
I could solve it for me with the option
acpi=oldboot
like told in this posting:

next, search for other threads about same kind of problem,
all about "poweroff fail at shutdown"
there are different settings,
some could solve it with disabling the KMS (kernel-mode-setting,
thats the option: nomodeset
on the boot-line).
-
shutdown with poweroff did work in old ubuntu-9.04 with my hardware,
the new kernel did break it, with its new acpi.
-
check your /var/log/messages like


grep ACPI /var/log/messages | grep Error

or only for the ACPI entries about detecting the acpi-bios-settings from the hardware.
