Hi!

Problem solved. It has nothing to do with XFree86 version.
It was due to installed fonts. Installing xfonts-greek-ph-scalable
and xfonts-scalable-nonfree and restarting xfs then the X server seems to
have solved the problem. However, I made other changes so I'm not 100%
sure (downgrading xfree86 from 4.3.0-pre1v1 to 4.2.1-11, removing some
fonts, ...).

Sorry for the noise,

Lucien.
