Comment 4 for bug 1319756

HI,
my setup:
- Lenovo T530 with NVIDIA Corporation GF108M [NVS 5400M] (rev a1)
- Ubuntu 14.04 with mainline kernel 3.14.9
- NVIDIA driver nvidia-331-updates:

My computer hanged during hibernate resume just after reading the image from the disk.
I found working solution by reading non-editable file: /usr/lib/pm-utils/defaults
This worked for me (so now hibernation works again):

1.) echo "HIBERNATE_RESUME_POST_VIDEO=\"no\"" | sudo tee /etc/pm/config.d/hibernate
2.) Just to be sure (probably unnecessary):
sudo update-initramfs -u
sudo reboot

3.) Test
sudo pm-hibernate

4.) Alternative test:
# press ctrl+alt+1 (go to virtual terminal)
sudo pm-hibernate

PS: My grub params in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="noquiet nosplash acpi_osi=Linux acpi_backlight=vendor acpi_sleep=s4_nohwsig loop.max_part=63 loop.max_loop=64"
