<ask> My Ubuntu 10.10 don't have hibernate mode

[Matadewa]

hi all. . .
i wonder why my ubuntu 10.10 don't have hibernate mode, as i remember in my previous install ubuntu 10.10 (in sama notebook) it's available
i already don't have hibernate mode since, i format my last install ubuntu because driver vga. . . so i think it's not because not compatible software
if it's hidden by somethings or bug how to show it again?

Most likely you have not mounted the swap partition.Open a terminal and post output of
free -m will tell us if the swap partition is mounted.

If not post output of
sudo blkid
sudo fdisk -l
cat /etc/fstab
cat /etc/initramfs-tools/conf.d/resume


Good luck

Your Swap partition should be greater than or at least equal to the amount of RAM ;-)

Please post the output of this command.

Applications > Accessories > Terminal:


free -m

i already set my swap 2x ram
my ram is 3gb so my partition for swap is 6gb

this is code for "free -m"
total used free shared buffers cached
Mem: 2688 979 1709 0 82 482
-/+ buffers/cache: 413 2275

It would be helpful if you posted the information requested in post #2 as it seems your swap partition is mounted
Swap: 5999 0 5999

i already try check if my OS support hibernate mode or not
with code

pm-is-supported --hibernate
echo $?
pm-is-supported --suspend
echo $?

and both of them give return value 0 which mean supported right?

but when i try this code

pm-is-supported --suspend-hybrid
its' give return value 1, which mean not supported

then i try to enter hibernate mode with terminal by

pm-hibernate
and it's works
but in top right toolbar it's still don't have list for hibernate
what is mean?

sory if this post too long
and sory again for my bad atitude

/dev/sda2: LABEL="Swap" UUID="8cc28e62-eccc-43e5-8a0d-0f8d3f98927a" TYPE="swap"



RESUME=UUID=47ed0764-0019-4d04-816b-9226db0af5cb

You need to change the value of /etc/initramfs-tools/conf.d/resume
to the value specified by the sudo blkid command, as that is what specifies where it should look to resume from hibernate.

Then reboot to use the new values.

Good Luck

sory i still don't too understand

this is default value of /etc/initramfs-tools/conf.d/resume

RESUME=UUID=47ed0764-0019-4d04-816b-9226db0af5cb

i just change it to this

RESUME=UUID="8cc28e62-eccc-43e5-8a0d-0f8d3f98927a

or copy all, like this

/dev/sda2: LABEL="Swap" UUID="8cc28e62-eccc-43e5-8a0d-0f8d3f98927a" TYPE="swap"

thanks for reply

[plucky]

Change it to
RESUME=UUID=8cc28e62-eccc-43e5-8a0d-0f8d3f98927a
so that it knows where to go to reload the hibernate information.

Then reboot

Good luck
