Hi,

I've been using the same PC with a Matrox G450 on AGP with a trusty old 
iiyama CRT monitor (Vision Master pro 410) for years.  System is running 
FreeBSD 6.4-RELEASE-p1

Having just upgraded to Xorg 7.4 from 7.3 and following the instructions 
in UPDATING I cannot get a stable picture.

Using my stock xorg.conf (see below), or a brand new config version 
created by "Xorg -configure" I get an extremely noisy (but stable) image 
if I lower resultion from my normal 1280x1024 to 1027x768.  At the 
standard resolution the monitor is unable to sync.

I've tried with and without DDC and with and without 
HorizSync/VertRefresh and with and without SyncOnGreen (my monitor has 
always product a slightly sharper picture with the latter).

Any ideas?

Cheers,
--
