Setting the screen grid size - asking, once again

[John Desmond]

Salutations, gentlefolk!

About six days ago, I asked:

<<

In Kubuntu Linux 8.04.1, kernel 2.6.24-14, KDE 3.5.10:

The standard screen grid is 5 lines horizontally, 11 lines vertically.
I would like to increase those numbers (ie, make a 'finer mesh' of the
grid) to about 8 and 14.

Might there be someone out there in cyberspace who knows:

A: Is this possible ?

B  If so, how do I do it ?

Yours, John Desmond
