[ubuntu-uk] Command line editing

[Keith Bowerman]

I wonder if someone brighter than me could help this old codger.  I
installed Dapper on a new machine but the screen resolution was no
better than 640x480 and with a 19" monitor it was like being at the
pictures.  So I edited the xorg.conf file, but with disastrous results -
no desktop! I can remember what alterations I made but I have no idea
how to edit the file from the command line.

Can someone please point me in the right direction.

Many thanks,

Keith.
