I don't have an issue per se, but am here looking to improve my setup.
I run an ASUS eeepc 1201N, dual booting Ubuntu and win7, and it was installed as 10.04 (made the Upgrade (not reinstalled) to 10.10)
I use it mainly for Mathematica/random web use/research(pdf/djvu/whatnot library)/ssh'ing to my box at home.
This is my second Ubuntu machine/install, but I still find things to customize/upgrade almost everyday, as I guess is common place amongst Linux users. Therefore, I reckon I might have a lot of 'trash' lying around the machine, slowing it down and taking up unecessary space.
Probably the most common solution is reinstalling it from scratch, and I will eventually do it once I have less work to do.
Care to guide me through the process of cleaning it up? Any common tips?
Here is the output of dmesg. Some warning I am not paying attention to? Some obvious process I can tweak to improve boot time?
I use gnome and am only running pidgin, chrome and terminal (two tabs (one is ssh, other where I got this output)) and am connected using wifi. Why the 450MB of used memory?
<user>@<host>:~$ free -m

Mem: 1759 1452 306 0 299 703

I followed this page to set up a swap file, seeing as I had not made a separate swap partition. However, it never gets used and I cannot hibernate (don't remember being able to, previously)

What other info can I provide? Feel free to redirect me to the proper community to find what I seek.
Thank you for your feedback.
