[SOLVED]change size of swap partition

I have got the problem as it will not active swap partition as i need swapon it each time after my restart linux.

Dear JanC

Thank you for the replying

the GParted's information do not provide the UUID # of partition.

SOmeone replied me on another linux forum which solved my problem, below I just copied the replied to my question

You probably lost your quiet Usplash also.

Go to terminal and run:
Code:
sudo blkid -c /dev/null
That will display something like this:
Quote:
/dev/sda1: UUID="5A3CAE183CADEEE7" TYPE="ntfs"
/dev/sda5: UUID="3f6a93da-cbc0-4203-92ce-42ff70394f0a" TYPE="ext3"
/dev/sda6: TYPE="swap" UUID="5b397135-2a82-4933-aefd-00d7ff23b413"
/dev/sda7: UUID="cb8d8925-8059-46bc-8312-9ce5f42afa91" SEC_TYPE="ext2" TYPE="ext3"
Note: The UUID #'s are in parenthesis. DO NOT include the parenthesis when you replace the UUID's in the following files! BTW the "-c /dev/null" is necessary because if you run blkid without options it reads from its cache file. If you've run it before and any partition has changed you'll get erroneous results.

Now run:
Code:
cat /etc/fstab
You'll undoubtedly see that the UUID's for SWAP are different. Here I like to create a simple backup of the original /etc/fstab using copy-n-paste and either Abiword or Open Office so if I hose things I can put things back in their original state! Do NOT be concerned at this point if the partition #'s are different! DO NOT change a partition #! Change nothing but UUID's!

To edit that file run:
Code:
gksudo gedit /etc/fstab
It's much, much easier to cut- copy-n-paste! Just be careful! And when you're done editing remember to click on Save, then go to File > Quit!

Now on to /etc/initramfs! Run:
Code:
cat  /etc/initramfs-tools/conf.d/resume
That UUID should (but won't) match the UUID for SWAP in blkid so to edit:
Code:
gksudo gedit /etc/initramfs-tools/conf.d/resume
Again be sure to save > file > quit after editing! Now one last important thing:

In terminal:
Code:
sudo update-initramfs -u
Be patient! It takes a minute or two to run! Wait until the command prompt (like lance@lance-desktop) shows up again!

Clear as mud?

BTW my problem solved but I can not edit the title of this message post .

Thank you again
