As I wrote I have on my computer dual boot Lubuntu and Win (I have recently installed Lubuntu because I don’t like direction of Windows development) and I found that there are few things which doesn’t work as I’m used. One of them is hibernation. I don’t know if it’s because my specific configuration (dual boot) or it’s a default setting, but you need to configure hibernation in Lubuntu 14.04 manually.
How to manually configure hibernation in Ubuntu, Lubuntu, Xubuntu, Kubuntu 14.04
Run swapon -s to find out if you have swap enabled. You should see something like this:
Filename Type Size Used Priority /dev/sda7 partition 2096124 0 -1
Originally I saw only first line so I realized that I need to set up the swap space.
How to set up the swap space?
Gparted (it’s installed under
System tools) and take 2048MB (2GB) from some disk partition with free space. I took 2GB of “free space” from Windows Disk C. Warning: Every time when you deal with a disk create a back-up!
Right click on “free space” partition > “Format to” > linux-swap. Apply all changes. It will take a while so go to kitchen and clean some dishes.
When is everything done right click on newly created linux-swap partition > Informations > Get UUID (my is a6d4c93d-85f2-4c08-9a80-a1e18264846e) and reboot.
Swap space is created and not we need to activate it on startup
gksu gedit /etc/fstab a add into new line
UUID=a6d4c93d-85f2-4c08-9a80-a1e18264846e none swap sw 0 0 (don’t forget to use your own UUID) and save the file.
2. Enable new partition with command
sudo swapon --all and check if it’s really works with
swapon -s. Reboot to make sure it starts when you turn on computer (
3. And now 2 last steps and Lubuntu hibernation will start to work. Run
gksu gedit /etc/default/grub and find
GRUB_CMDLINE_LINUX="". Change it to
GRUB_CMDLINE_LINUX="resume=UUID=a6d4c93d-85f2-4c08-9a80-a1e18264846e" and save it.
gksu gedit /etc/initramfs-tools/conf.d/resum and make sure that it contains
resume=UUID=a6d4c93d-85f2-4c08-9a80-a1e18264846e (your own UUID, remember) and save the file.
sudo update-initramfs -u and reboot.
You just set up hibernation for Lubuntu 14.04 (and also for Ubuntu 14.04, Xubuntu 14.04 and Kubuntu 14.04).
Update: Whereas you made changes to Disk C and things went wrong you see some strange error message when you try to access disk C. You didn’t make a backup and therefore you are starting to be really nervous. Don’t worry just run a command sudo ntfsfix /dev/sda5 which will fix your broken NTFS partition (sda5 is nick name of Disk C in my Lubuntu, your nick can be found in gparted > disk C > right click > information).
