clearing disk space in CLI?

[sylvaine]

Whilst trying to get my GUI back, I got the error message "Keyboard initialisation failed. This could be a missing or incorrect setup of xkeyboard-config.", which google tells me means I need to free up disk space.

As far as I know, I need to use the rm command to do this, but how do I figure out which files to delete without my GUI? I'm deathly afraid that I'll delete something I need.

(Please bear in mind that I'm an utter noob when it comes to Linux.)

Thanks for the input! Deleting files on home didn't have any effect, unfortunately, the problem seems to be with the root itself, which I'd rather get IRL help with.
