My computer (N550JK) has 12 GB of RAM and 1.5 TB HDD storage. My HDD contains 16 GB swap partition, which should be enough to hibernate, I think.
I have made a fresh install of Ubuntu. Since my graphics card (NVIDIA GeForce GTX 850M) is very messy with nouveau; I have started the live CD with nomodeset kernel argument, it I don't do this I get a lot of errors and my system hangs. After I have successfully installed my Ubuntu with latest updates and 3rd party software such as flash, decoders, etc. When I started Ubuntu, as a result of nouveau-incompatibility; I had a login loop etc. I followed these links and solved my graphics card issues (actually I hope):
- 15.04 and Nvidia: login loop
- http://rajat-osgyan.blogspot.com.au/2015/03/how-to-install-bumblebee-on-ubuntu.html
I have installed nvidia-352 drivers from PPA, and bumblebee from Ubuntu repositories.
Since my keyboard has non-functional screen brightness FN keys, I have added acpi_osi= kernel arguments to GRUB_CMDLINE_LINUX_DEFAULT= part of the /etc/default/grub file. And it worked! My FN keys issue is solved!!!
For informative purposes, I also removed quiet splash kernel options.
I have mentioned all of those above because they are the only things that I have done after installing linux.
Well, here is the main point. At first after being sure that my graphics card configuration is fine, I have run the pm-hibernate as root, and then it worked! :D Then, I decided to enable it on power menu, so followed instructions at this link:
How to enable hibernation in 15.04?
Then, I used my power menu to hibernate, it seems it hibernates well. But when I try to resume, I got,
- Messages related to loading image from swap.
Suspending console(s) (use no_console_suspend to debug)(this is the last message)
Then, my system hanged.
After that I was curious, did I get the same problem with pm-hibernate? So I used pm-hibernate to hibernate again, and the problem occured again.
So what should I do to make hibernation work? If you need further information I can take snapshots of my system, record a video or send log files you want.
