I have just installed SolydX (Debian based) onto a laptop with the following specs:

-Toshiba Tecra A4 -800MHz Centrino CPU -nVidia 6600 GPU -512MB RAM

After installing Conky to monitor my system, I noticed that there is no Swap space showing. I made a 2GB Swap partition on install. I have checked the fstab file and all looks good (it was populated by the installer).

Most answers I've found so far use the swapon command, however when I try these commands, I get a 'command not found' error.

How can I get my system to use the Swap space?

Below is my fstab file

proc /proc proc defaults 0 0 UUID=49f4751f-4ad9-4f3e-baa8-853d3d43153c / ext4 rw,errors=remount-ro 0 1 UUID=b4e77f64-86d7-4a72-888d-fbbcc5d1045c /home ext4 rw,errors=remount-ro 0 0 UUID=3b3aec73-825f-4ec0-96c5-f9c79d599f9e swap swap sw 0 0

    Are you root when you call swapon? swapon is in /sbin, a path normally only added to root's environment. Commented May 11, 2014 at 18:36

    use blkid as root (sudo blkid) to check that the UUID of your swap partition is the same as the one in fstab. Commented May 11, 2014 at 19:56
  • I do prefix with sudo every time. I have also checked the UUID and they match Commented May 12, 2014 at 20:41

You ought to have the swapon command.

You would need to be logged in as root to use it; if you are not, then you probably don't have /sbin in your path, so you're not finding it.

Did you try

sudo /sbin/swapon -a

For the swap not to be used automatically, there's probably a real problem, but that should show you the error.

If you still get 'command not found', something's really wrong with your system—you could maybe try reinstalling the mount package.

  • Told APT to reinstall mount to see if that fixed it and got an error suggesting I run 'sudo dpkg --configure -a '. After running that, the 'swapon -a' command now gives an error "swapon: /dev/sda3: swapon failed: Invalid argument". 'swapon -s' shows no swap partition mounted. Using GParted, I selected to make a new UUID, then ran 'sudo /sbin/swapon -U 767cd69b-dc33-4d5d-8d7e-b278d78ba9c8' with the same "Invalid argument" error. Commented May 13, 2014 at 6:23
  • Just tried GParted's option to turn swap on and got the following "swapon: /dev/sda3: found swap signature: version 1, page-size 4, same byte order swapon: /dev/sda3: pagesize=4096, swapsize=2147573760, devsize=2147565568 swapon: /dev/sda3: last_page 0x80016000 is larger than actual size of swapspace swapon: /dev/sda3: swapon failed: Invalid argument" Commented May 13, 2014 at 6:29

Using GParted, I deleted the swap partition and made a new one. After selecting swapon, swap activated and Conky mirrors this in it's display.
