I use Ubuntu 11.04 64bit on a notebook with 4gb of ram. The problem is that I seem to use only 1.8 of 4 gb.

the output of ~$ free -m is

total used free shared buffers cached
Mem: 1852 1678 173 0 144 802
-/+ buffers/cache: 731 1120
Swap: 5960 0 5960


any help please?

are you sure you have 4GB of RAM? (and not 2GB)

Some RAM is probably being siphoned off for an integrated graphics chip, but that won't be anywhere near 2GB

*edit*
Just FYI,
you can query exactly what memory your machine has by using

sudo lshw -C memory
