My first post ever, I will try to be as detailed as possible
to convey the
problem that i'm having.
The Problem: Monitor flicker in the lower right quadrant of
screen, worse in
daylight hours, which leads me to believe that refresh rate
is around 60Hz.
This occurred previously in the same computer, same monitor,
using a Diamond Stealth 4MB pci video adapter under FBSD
4.5, X 3.3.6. Setting the Hor. & Vert. frequencies to
monitor specs (H 30-96 V 48-160) in XF86Config quickly
resolved this problem. The resolution used in this instance
and previous has remained constant at my chosen preference
of 1024x768 at default 24bit color. This flicker is much
more prevalent on light colored screens than is on dark
colored screens, dark xterms, etc. . Another issue that
seems very peculiar is the fact that upon first installing
4.6-RELEASE, the console mode seems normal. However, after
configuring X with the xf86config script utility...and after
starting X and returning to console mode, a slight jiggle in
text is noticed. Again, I've seen this before but was
completely able to resolve it using the correct IBM P200
frequency settings.
Over a period of two weeks I have made numerous attempts to
resolve this issue.
Attempts To Resolve Include:
Using several different frequency rates, and all the
possible defaults frequency rates.
Tried running xvidtune, which also had no affect on flicker.
Using different Mach64 supported drivers within the
xf86config utility.
I even tried the gui xf86config at a later time.
My latest attempt was yesterday. This from a previous post
from freebsd-questions about another who has this
same/similar problem.
I also tried the possible solution of adding option:
"composite_sync" "off"
to Section "Device"
in the /etc/X11/XF86Config file. Further, tried new
frequency settings after making this change.
Still to no avail.
Running: FreeBSD 4.6 / X 4.2
Monitor: IBM P200
Monitor Frequencies: H = 30-96
V = 48-160
Video Adapter: ATI Rage Pro Turbo 3D 8MB pci (#17 driver
from xf86config utility)
Further research of the problem has pointed me to
possibility of the dot clock which is currently commented
out in my XF86Config, or is there a possible kernel hack
that would allow better acceleration of said video adapter?
Finally, how do you know what you exact refresh rate is and
how do you change that--I think this may be the resolve but
must be missing the boat somewhere.
Any help at this point is welcomed.
XF86Config File is listed below.
Thanks In Advance,
Rob
