I have just started to have this problem, at least i think it is this problem but mine hangs on the splash screen. It happens everytime i shut down. If i hit F1 early in the shutdown process i get a recurring message like this hub 1-0:1.0: connect-rebounce failed, port 6 disabled hub 1-0:1.0: connect-rebounce failed, port 5 disabled
There is no evidence of "stopping" in the kern.log uname: 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux lsb: Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty system: Intel® Core™2 CPU 6600 @ 2.40GHz × 2 GeForce 7950 GT/PCIe/SSE2 64-bit -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1315425 Title: Cannot shutdown or reboot system from Gnome or gnome-terminal Status in “gnome-session” package in Ubuntu: Confirmed Bug description: Hello folks. I use a ThinkPad R61 with a NVIDIA Corporation G86M [Quadro NVS 140M] (rev a1). On my laptop I have installed Ubuntu GNOME 14.04 via an Upgrade from Saucy. I cannot shutdown my laptop from within a gnome- session. When I choose Shutdown or Reboot from the Gnome Menu, the Gnome- Desktop is obviously terminated properly, but the laptop don't power off. The display gets dark but the leds and the system fan stay on. The display backlight is on, too. In this state I'm unable to get via Ctrl+Alt+F1 in a console or something like that. I could only power off the laptop by pressing the power button for some seconds. The same happens when I open a gnome-terminal and type "sudo shutdown -h now" or "sudo reboot NOW" there. This happens while using the nvidia drivers 304.117 or 331.38. I've tested all of the following packages. rc nvidia-304 304.117-0ubuntu1 amd64 NVIDIA legacy binary driver - version 304.117 ii nvidia-331 331.38-0ubuntu7 amd64 NVIDIA binary driver - version 331.38 rc nvidia-331-updates 331.38-0ubuntu7 amd64 NVIDIA binary driver - version 331.38 I use GNOME Shell 3.10.4 and kernel 3.13.0-24-generic. Does this happen to anybody else?
