Replace 4096 MB (4G) to your desired size. To create a file for swap if you don’t have it, run following commands one by one:Ī.) Pre-allocate a disk place for a file via command: sudo dd if=/dev/zero of=/swapfile count=4096 bs=1MiB This step is only for those who don’t have a swap partition, since a swap file can also be used for hibernation.
#Itab hibernate update#
Save the file and update the Grub via command: sudo update-grubįinally reboot your computer, open a few app windows, and run systemctl hibernate command to test if it works now! Enable Hibernate on Swap File: When it opens, add resume=UUID=xxxx ( replace xxxx with the id you copied in previous step) as value of “GRUB_CMDLINE_LINUX_DEFAULT”. To do so, run command in terminal to open the config file: sudo gedit /etc/default/grub It will be used in next step.īy adding a Kernel parameter into boot menu entry enables the hibernate in my case in both HP and ASUS laptops.
Now find the UUID (universally unique identifier) for the area by running command: cat /etc/fstab |grep swapĬopy the UUID for /dev/sda3 in my case. In my case the swap is a partition: “/dev/sda4”. Or if it says no swap or a file, go next step: ‘ Enable Hibernate on Swap File‘ If it outputs “ /dev/sdax partition …” continue this step. Open terminal (Ctrl+Alt+T) and run command tell the swap area: swapon -show It can also be used to save your system status via hibernate. The swap area is used when the memory is getting full. So it does not work and just log into blank desktop? Try enable this feature via following steps. Next boot the machine again, and see if it restore your system status after login. The command will turn off your computer/laptop. Save you work before running the command!! Then type user password when it asks. To verify if the functions works, open terminal (Ctrl+Alt+T) and run command: systemctl hibernate
“Failed to hibernate system via logind: Sleep verb “hibernate” not supported”. NOTE: The command below won’t work for secure boot!! You have to disable it in BIOS/EFI for using hibernate.
Hibernate does not work in my laptop since Ubuntu 20.04 (maybe, can’t remember it), though it works in Debian 11 bullseye. It may NOT work if you’ve used Grub-Customizer to edit the boot-menu!! For other desktop environments, you need to replace gedit in following commands with your favorite text editor, or use the universal nano command line editor. NOTE:This tutorial now is tested and works on my Ubuntu 22.04 Laptop with default GNOME. Next time you boot the computer, it restores the system status exactly as it was. It moves the content from RAM memory into swap area in hard disk, then shutdown your machine completely. Similar to suspend, hibernate can be used to save your system work.
