right, right agree. but i'm curios if the stty ( for non graphical console
) can be changed without rebooting the system. Now thinking, i 'm pretty
sure that stty doesn't support resolutions over certain limit (120 ? ) so
there is no way to make it 1440x900.

after some extra session of google, i came out with this
http://www.acm.uiuc.edu/workshops/cool_unix/stty.html:"
If it seems like the program you're running thinks your screen is bigger
than it is, maybe it does. You can probably fix it. Most terminal programs
display text in 24 rows of 80 characters. Using stty's rows and
columnsoptions let you reset these manually:

stty rows 24 columns 80

Or X (when configured right) will do it automatically

eval `resize`

(Remember the backquotes!!)
"
I'll try it later today to see if it works.
