Linux-swap drive not recognized.

hi sTempler..
This is a very common experience when you keep your laptop under hibernation mode..(I have also experienced the same thing....:) )

I got the fix by looking here:

https://edge.launchpad.net/ubuntu/+bug/66637

also JFYI Try these from a terminal.

sudo mkswap /dev/hda1
sudo swapon /dev/hda1
free
(where hda1 is your swap partition)

If it works (from the output of the last command), reboot and see if your swap mounted automatically.

I read through that post but I am unable to save the fstab and resume files. It says I do not have the permission. How do I replace them?
I am the only user on this PC. Also How do I login with the root account?

use sudo... try this command in a terminal: sudo nano /etc/fstab.. or gksudo gedit /etc/fstab..
And to save the file in nano use cntrl+x after you have made the changes... (Root access is disabled by default in ubuntu)
for more info on sudo ref:
https://help.ubuntu.com/community/RootSudo

secondly If you want to login as root without sudo try this:
$ su
$ password: rootpassword
in case you cant login as root (assuming you havent set your root password) follow these simple steps..
$sudo passwd root
$New Password: typeyourpassword
$Retype password: Again
This will set your root password..

Then you can log in as root by doing as mentioned above,

hope it helps,

I was able to save the files and then I tried two things and the results were as follows;

Hibernating
           The computer went through the normal hibernation process and powered off which it wasn't doing before. But when I power
     it on again it boots rather than returning from hibernation and the swap does show up in the system monitor.
      "used swap 0 bytes of 1.1 gb 0%"

Shutdown
           When I reboot the system the swap does not show up in the system monitor
      "used swap 0 bytes of 0 bytes 0%"

Should I run the diskmount script?

If it helps, this is my fstab

please paste the output of sudo fdisk -l and sudo mkswap /dev/hda1
sudo swapon /dev/hda1
free
(where hda1 is your swap partition)

If it works (from the output of the last command), reboot and see if your swap mounted automatically.
Please report any errors here....

I went through all of the steps again and did "update-initramfs -u", retsarted and still not mounting the swap.

Thanks Bhavani Shankar, that solved my question.

You are a golden god. Thank you VERY much for that.

no mention.......Glad that I can help and it worked.......:)
