My Precise Pangolin sometimes won't shut down - the screen is black with text on it. Mostly last line says something like stopping winbind deamon (sometimes also virtualbox, which is above winbind daemon;)

Edit: sometimes the last line says running unattended updates.

And it stays like this for about ten miutes. Then I usually hold the power button for more than 5 seconds to shut it down. It's very unpredictable. Sometimes the computer shuts down without problem and sometimes it hangs.

I've tried many ways to shut it down: HW button, panel applet, sudo shutdown -h now, sudo poweroff, sudo halt, etc. Even i tried sudo reboot or restart from panel applet. They also have this problem. Sometimes it works correctly. But every method named hung at least once on the same (damned) line.

My specs:

  • FUJITSU SIEMENS LIFEBOOK E8310,

  • Intel Core2 Duo T7300 @ 2.00GHz,

  • 3GB RAM,

  • GPU: Mobile Intel(R) 965 Express Chipset Family

  • Ubuntu 12.04.2 32bit, 3.5.0-41-generic kernel (but it did it on older kernels and 12.04.x systems too).

Any ideas what should I try next?

This happens to me but only for about 30 seconds (it doesn't vary as the time of yours does). I have the same version, just 64 bit; a Toshiba Satellite Pro with Intel Core i3, 4 GB of RAM, and I think the kernel version (on /proc/version signature) is 3.8.0-32.47~precise1-generic. The rest of what you mentioned is the same (it doesn't depend on shutdown method, etc.). –  JMCF125 Nov 7 '13 at 22:05

There was no variation in time - when it hung, it was forever (or until I forced it to shut down by holding the power button). And I'm saying "was" because I did a fresh install of 13.10 and the whole problem is gone (also flash plays much better, no yellow dots anymore). I went for Saucy since there is gonna be LTS on April so I could handle this as a small adventure before settling again with next LTS ;) –  jan Dec 16 '13 at 17:45
    
good, then you're fine now. I'm investigating into it, but I won't install newer Ubuntu versions. I'll use Arch Linux with XMonad, it's awesomly fast. You can try other desktop environments/window managers on Ubuntu simply installing them: try DWM (or XMonad), Xfce, KDE, and Gnome (google install <name-of-the-wm>). –  JMCF125 Dec 16 '13 at 18:29

I tried many of them (really liked XFCE and LXDE) but later I realized Unity suits me best :) I even took a look at Mint's MATE and Cinnamon but they can't compare to Unity (in my eyes). And Unity is also much faster in 13.10 than in 12.04 ;) I just hope Canonical won't screw up Unity because I see nowhere else to go (for now). –  jan Dec 29 '13 at 22:37
    
In Mint I only tried KDE (in a VM), before I came from Windows. I hadn't heard it is faster yet (it is indeed slow in 12.04), but I don't care anymore, see this. This compromises one of the reasons I came to Linux, so as I said, I'm changing to Arch. But you've got to try XMonad (I'm using it right now in Ubuntu). –  JMCF125 Dec 29 '13 at 22:42
