I recently fresh-installed Ubuntu 13.10 on my Toshiba Satellite L455 after several unsuccessful attempts at upgrading from a previous version. After resolving several minor glitches I find myself unable to resolve this very annoying occurrence: having to completely shut down and rebooting my computer every time it goes into hibernation, whether from inactivity, or after closing the lid and opening it back up--like I used to do.

In looking at other Forum questions, someone suggested finding out some additional information in order to better address the issue, so I went ahead and obtained it, in case this may expedite attempts to resolve the question. So I ran

sudo lshw -C network

and obtained the following result:

I'm also running Gnome Classic. But it happens in any of the desktop environments available. Any help would be appreciated.

I had the same problem. I think i found the resolution, installing Ubuntu on machines with Nvidia driver screws up the display. By default Ubuntu uses its own video drivers, thats why im having issues with hibernation.

I fixed it by going to Software & Updates > Additional Drivers > change driver to NVIDIA binary Xorg driver, im using Nvidia Xorg driver VDPAU library nvidia-319, and now it hibernates and wakes up correctly. If you have other video drivers change it to whatever you have.

I don't know what I did, but after installing and switching to a different desktop manager in Gnome it hasn't happened again (I don't remember the name, and I don't want to log off to find out just yet, but when I do, I'll post here). – user236707 Mar 17 '14 at 17:55
