[Bug 118745] Re: Font sizes in Gutsy are vulnerable to bad X.org DPI detection

Fwiw, bulletproof-x is just a failsafe mode for X, and wouldn't have any
bearing on this issue.

It sort of sounds like the issue here is that Gnome is guessing the
correct dpi by looking at the refresh rates.  Unfortunately, in most
cases the refresh rates are themselves just guesses done by the xorg
postinstall script when xresprobe fails to detect the card (which
happens a lot).  If this is indeed the case, then basing a guess on top
of a guess is bound to lead to rather unpredictable failures.

In talking with seb128 about this, it sounds like the best option for
now is to go back to a hardcoded dpi setting.

Assuming my hypothesis is correct, a couple workarounds to try would be
to a) try running with no xorg.conf.  b) try fixing the HorizSync and
VertRefresh settings in the Monitor section of your xorg.conf (see your
monitor for correct settings).  No guarantees that this would fix things
in all circumstances, but if they fix it in at least some, then that is
added evidence that the core issue here is mis-detected refresh rates
(which is bug 3731).
