Disk thrashing in Ubuntu Gutsy


Disk thrashing (excessive disk i/o) causes decrease/loss of responsiveness in Ubuntu Gutsy.


The thrashing was caused by the swap not being turned on properly.

The swap was not turned on because fstab had the wrong UUID.Fixed based on instructions here:

- type



- note the UUID of the partition that should be the swap

- edit /etc/fstab so that the UUID matches

System Details:
Compaq Presario R3000, nVidia video card, Ubuntu Gutsy 7.1
