Hello all,
I have just switched monitors and X now starts in 640x480. I intend to
make it work at 1280x1024, and have changed DefaultDepth and Modes
lines in xorg.conf accordingly. The console works at 1024x768 as
usual, but I have compiled that into the framebuffer. Any suggestions?
Thanks,
Vlad

how about not using modelines at all?

I've tried commenting out the modeline, to no avail, and the
DefaultDepth, also with no result. I've checked the logs and found
nothing out of place. Attatched is my xorg.conf, should anyone find it
meaningful.

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
1920x1440@75 for a 17" monitor -- not by far a wiz with this, but...
is this right??)

I find I have to set "IgnoreEDID" "True" in my xorg.conf card options to get it to work. I am not entirely sure why - but it works. I think it ignores what the monitor says its settings are and then uses settings you specified, but I could be wrong. I'm using an nVidia Ti4200 on a 17in Relisys TL766 (model number might be off for the latter, I'm at work at the moment).
PS: Can we please try to trim the emails down a little? Quoting several paragraphs of settings makes for a long email ;) Cheers

something like that. I don't usually set it, but I think that's mostly
because the only time I have to specify settings myself is when the
EDID or whatever isn't working properly. Monitors' support for this
mode-gathering stuff seems to vary inversely with it's age. Many of
the older ones I have refuse to help X configure them at all.

++. It's so true.

I am not familiar with ddcxinfo-knoppix, but it probably lists modelines
from up to 3 different sources. The graphics card can supply a list of
available resolutions -- that's where 1920x1440@75 came from I bet.
The monitor's refresh rates can also be used to extrapolate possible
modelines -- I don't know how to do this, but aside from this program,
there are websites that can do so for you. Finally, the VESA standard
defines what would likely be called generic settings that are supported
by any VESA-compliant monitor and graphics card (just about all of them
you can still physically connect to new computers, nowadays). These
standard values are a good place to start, as your monitor should work
for them, and you should be able to find one (1280x1024@70, maybe)
that your monitor supports and that looks nice and doesn't flicker too
much, and performs well on your hardware. the Modes line is meant to
be a list of modeline names, so you may or may not need the @70 part
depending on where the modeline came from. the X logs should list many
modelines which X came up with after probing the hardware, and you
probably want to use a name from the desired one of these.
Have you tried looking up online and entering the refresh rates
manually? I highly recommend doing so.
Best of luck,
dan.

I'll add this to the list of things I learned today. Apologies for the

I am now using a VESA-compatible modeline for 1280x1024@75 (not sure
about the last one). I just pasted it from ddcxinfo-knoppix, knowing
the monitor would work with these settings.
One more question, though. If I switch back to my older, smaller
monitor and forget to change the modeline, will it get fried? I seem
to see this warning quite often.
Thanks for the help,
Vlad

How's my English? How about my Netiquette?
Do mail me if something is wrong with my behaviour. Thank you.

no inconvenience here, but others on the mailinglist have no doubt
learned as well .. so thanks for the convenience ; )

that looks good. the @75 is just part of the arbitrary modeline name,
but actually refers to the refresh rate being used - a nice, fliker
free 75Hz (or kHz, whichever it is i can't rememver)

I have seen that warning too, but I haven't yet been able to actually
break a monitor like that. I think the current technology (circa early
to mid 90s and up) no longer has this problem. However, don't take it
from me as fact, but a guess correlating with the experiences I have
had. Usually, newer monitors simply show an 'out of range' box on the
screen, and older ones show an image composed entirely of quickly
waving gray black and white horizontal lines; the monitor in this case
has always happily performed afterwords just fine at supported
resolutions.
there is one thing i would mention though. You know how as monitors
wear out they get blurrier and blurrer, and image quality decreases?
Well, setting the refresh rate too high on some older, cheaper
monitors seems to result in a much accellerated blurification process.
