Did you create a swap partition when you were installing the system? If you do a "fdisk /dev/sda", change "sda" to your disk, you'll see something like this: Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 535 4192965 82 Linux swap / Solaris /dev/sda3 536 4427 31262490 83 Linux The command "free" can give you a hint about your swap space: newt (Linux)$ free total used free shared buffers cached Mem: 2074956 1926248 148708 0 27900 1252224 -/+ buffers/cache: 646124 1428832 Swap: 4192956 124 4192832 newt (Linux)$ Regards mg.
