12.04 shutdown freezes

[GrouchyGaijin]

Hi Everyone,

I just upgraded from 11.10 to 12.04 (yeah I did an upgrade and not a clean install) and am having a couple of issues. The most pressing issue is that 4 times out of 5 when I try to shutdown, everything seems to go as it should except the machine won't completely shutdown. Everything seems off, but my power light stays on and I can't start the machine again until I hold the power button in for a few seconds and kill the machine.

Has anyone else had this problem?

UPDATE

I looked about and found reference to a bug with Nvidia drivers and shutdown / restart problems in 12.04. The bug wasn't exactly the same as the problem I had, but it was similar. I updated my Nvidia driver to the one with (post release updates)(version current updates) next to it in the list of additional drivers and the problem seems to be fixed. Specifically the driver I'm now using is version 295.40

I'm going to wait a couple of days before marking this thread as solved.

UPDATE 2

The problem still exists.

I have the same problem with clean 12.04 install. Shutdown and Restart work ok from log screen though. So if you logout and the shutdown/restart it doesn't freeze. I've read that gnome-network-manager was causing such problems on 11.10 but I removed it and nothing changed. I just updated my ATI Radeon HD drivers to the latest from the official site. I will test and report.

I hope someone can help us!

Cheers...

Hey, thanks for the tip! I can live with needing to logout before shutting down, for the time being anyway.
This is pretty irritating, there is a bug with the version of Conky that ships with 12.04 that messed up a lot things. The solution is to downgrade to an older version of Conky.

Now this start / restart thing. Ugg

Two restarts and one shutdown with no problems
Before the update, every restart/shutdown was freezing. So the problem must be somewhere at the graphics card's drivers.

After I changed Nvidia driver, I too can restart, but shutdown still hangs.
( I think I can restart anyway, I did 4 in a row with no problem. I had thought that the problem was solved until I tried to shutdown.)

What driver exactly are you using?

What driver exactly are you using?

First of all, I noticed that the freezes appeared only if you wait sometime (minimum 5mins) before you do a shutdown/restart.
My graphics card is ATI Mobility Radeon™ HD 4650 Graphics and I downloaded the latest drivers from here

http://support.amd.com/us/gpudownload/Pages/index.aspx

I read that you have NVIDIA so you should try to do the same, with the official drivers (if any).

I was pointed to this post http://askubuntu.com/questions/10769...tdown-from-gui
from an answer to my question on launchpad.

The answer boils down to this seems to have been a problem since 11.10, although in 11.10 I had no trouble shutting down or restarting.

One person wrote that he found a solution by adding the following line to the file /etc/default/halt:

 
INIT_HALT = POWEROFF

I added this and so far I am able to shutdown without problem. So I think this is solved, but I'll wait a bit before marking it solved just to be sure.

I am glad to here that. I have no problems too since now but I'll keep that in mind just in case.
