memory-usage

I have just installed the standard default desktop configuration of Ubuntu 12.10 (Quantal Quetzal). My PC only has 1GB of RAM and is struggling a little. What steps can I take to reduce the memory overhead of the standard install? If it makes a difference, I use Firefox, and a terminal most of the time.

Simply running those two applications I see:

free -m
            total       used       free     shared    buffers     cached

Mem:           938        873         64          0          5      167
-/+ buffers/cache:        701        237
Swap:          959        158        801

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
