sometimes, Ubuntu is not running
in laptop mode, 

check if your running laptop mode by,

# cat /proc/sys/vm/laptop_mode

If it's 0, Ubuntu did not detect laptop mode. You can set it to 1 by,

# sudo /sbin/sysctl -w vm.laptop_mode=1

For memory tweaking constraints, 
You can set RAW parameters in the running kernel,
using sysctl by,

# sudo /sbin/sysctl -w vm.min_free_kbytes=<reserve memory for system>

the current default is 2039, but if you like to use the swap more than 
your memory, change it to higher values, I usually set it to 16384 for
256MB.

tweaking kernel settings is dangerous, make sure you save your work
before doing anything, it _will_ close the applications you are working
on.

and to make things permanent, edit /etc/sysctl.conf and add the words
after the -w.
