I find myself in this situation often, and usually, looking up
Horizontal Sync and Vertical Refresh frequencies for the make and model
of the monitor (rarely tricky) and then setting them in xorg.conf
solves the problem. For example:
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 31.5-64.3
VertRefresh 50-90
Modeline "1024x768" 85.00 1024 1032 1152 1360 768 784 787 823
EndSection
In this case I also used a modeline because the HorizSync and
VertRefresh settings didn't work at 1024x768 without it.
I emerged ddcxinfo-knoppix and when I run it with -monitor, I get a
lot of modelines, along with some HorizSync and VertRefresh values.
These are what concern me:
Section "Monitor"
Identifier "Monitor0"
# HorizSync 28.0 - 78.0 # Warning: This may fry very old Monitors
HorizSync 28.0 - 96.0 # Warning: This may fry old Monitors
VertRefresh 50.0 - 75.0 # Very conservative. May flicker.
# VertRefresh 50.0 - 62.0 # Extreme conservative. Will flicker.
TFT default.
# Default modes distilled from
# "VESA and Industry Standards and Guide for Computer
Display Monitor
# Timing", version 1.0, revision 0.8, adopted September 17, 1998.
# $XFree86: xc/programs/Xserver/hw/xfree86/etc/vesamodes,v
1.4 1999/11/18 16:52:17 tsi Exp $
# 640x350 @ 85Hz (VESA) hsync: 37.9kHz
ModeLine "640x350" 31.5 640 672 736 832 350 382
385 445 +hsync -vsync
<snip modelines here>
Does this program guarantee that the settings really do work for my
monitor or are they just generic? I need to know, especially
considering the remarks about frying. Also, just checking to see I got
it correctly: I would comment out all but one modeline and use that
one, right? Again, are all modelines listed supported? (This lists
[EMAIL PROTECTED] for a 17" monitor -- not by far a wiz with this, but...
is this right??)
