[ubuntu-za] 14.04 update problem

[Jan Greeff]

After I ran updates (which did not complete due to errors) on Ubuntu 
14.04 with Gnome desktop on my wife's desktop machine, the screen 
resolution is now so big that I can only see about half of the windows. 
Consequently I cannot change any settings because the "save" button does 
not show.

In addition, the machine has lost its Internet connection.

Any suggestions on how to resolve this issue will be appreciated.
