Setting the right resolution for your Ubuntu 8.04

I have just installed an Ubuntu 8.04 Hardy Heron and I noticed that I cannot modify the resolution of my screen since there is only one resolution available and its just so large that some parts of some of the application window I cannot be seen or accessed.

If you happen to be in the same problem with me right now, this is how to solve it:

1. Press Control-Alt-F1 to login into a text-mode terminal


2. Stop the GNOME Display Manager(gdm):
   

   # sudo /etc/init.d/gdm stop



3. Reconfigure your screen resolution:
   

   # sudo dpkg-reconfigure -phigh xserver-xorg



4. Start the GNOME Display Manager back again:
   

   # sudo /etc/init.d/gdm start



5. Then go back to your X-Window by pressing Control-Alt-F7

And thats it! Hope this helps.
