System getting stuck at log-off screen

Asked by Inkit

Hi,

While shutting down my system, it is getting freeze-d at the log-off screen (the ubuntu logo) that shows up before turning off.

I have to forcefully turn it off from there. :-(

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 11.04
Release: 11.04
Codename: natty

Please help.

Are there any bugs reported with ACPI?

Aw. This I was suspecting since beginning.

Am very naive user. Have no idea about ACPI. Have just heard about ACPI, noacpi, acpi=off, etc.
This while doing some research on a bug which has affected every tablet. The discrete GPU thing. I have ATI and intel graphics which leads to heavy battery discharge and over-heating because both of them are always "On". Power management is poor.
So to switch off the ATI one I read somewhere in a thread which says of adding " noacpi " at

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noacpi"

Is this a reason?

oh god that dual gpu stuff is a nightmare. Could be the issue. Does the boot option make things better. The noacpi will make the battery not report properly but may help the situation.

Little better but still it is getting heat up. :-( Yes. the dual gpu stuff is the worst nightmare one can ever have. Do you know any concrete solution to that?

Installing "ATI proprietary FGLRX graphics driver" makes it worse too. It never starts up after that.

But Sir, I believe the shutdown issue was there pretty much even before I changed the grub.

There is an app named bumblebee which may help.

What is the difference between noacpi and acpi=off. What is acpi anyway?

There is no difference as far as I am aware

Can you help with this problem?
