I have Xubuntu running on an hp elitebook i5 with 8gb or ram.

$ uname -a 
Linux HP-EliteBook-8470p 3.5.0-37-generic #58~precise1-Ubuntu SMP Wed Jul 10
17:48:11 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Normally I have to run Vagrant (virtual box), Firefox (15 to 20 tabs) and netbeans. Vagrant normally takes 1GB, Firefox almost takes on 1GB and it's the same for netbeans.

This still doesn't explain why my free memory is so low. I open htop and I see multiple instances of X.

Anyone know what the problem might be?

  • Sometimes, it might be the terminal. I use Xuxubntu as well, and when i leave my terminal (xfce4-terminal) open, it uses about 1-4GB of RAM. Close and open it again, or search about the xfce4-taskmanager to see who has taken the whole RAM. – Mohammad Kholghi Sep 5 at 10:28

Quite possibly one of the apps (perhaps Firefox or Flash) gradually leak memory. I have a very similar issue with long Opera sessions. I found that the best way to deal with this is to reboot often enough (basically, whenever the system starts swapping).
