Hi. We have an old computer at work that is only used for editing and saving documents, and sometimes surfing the net. Since it's an old machine, it's pretty low in the memory department.
The OS is Ubuntu 9.04 -the Jaunty Jackalope, GNOME version: 2.26.1. According to the System Monitor, there is only 2MB remaining disk space whereas there are only a few documents left on the computer! So my question is: Is there a similar "defrag" option in Linux? I want to free some space to get rid of the slow-response rate and the frequent crashes.
Btw, I am a heavy Windows-user since forever. I only use the word-processing programs in that computer. I've never tried installing in Ubuntu. I find the sudo codes confusing. Heck, I don't even know where to input those codes. So please, I need help. I tried running the Computer Janitor, but it says "Failed to run computer-janitor-gtk as user root. Unable to copy the user's Xauthorization file". I tried again and it says "Essential package dash is missing. There may be problems with apt sources.list or Packages files may be missing." I am starting to think it's because of a virus.
Please help! Links for beginners are highly appreciated!
