The easiest way to center your image is to use xvidtune. If that doesn't
work (e.g. in multihead setup), just increase/decrease the 2nd and 3rd
number (horizontal centering) or the 6th and 7th number (vertical
centering). Take to keep the distance between the 2 values constant (i.e.
always increment/decrement both simultaneously). Furthermore the
horizontal values need to be incremented/decremented in steps of 4 or 8

Yes. Although the manpage says that it shouldn't be necessary anymore to
write your own modelines, I have had to do so for every single X
installation I've done so far.


Ambition is a poor excuse for not having enough sense to be lazy.
