There are actually a ton of howtos for calculating modelines out
there, mostly dating from the not-so-good old days of handcrafted 
XF86Config files. For instance, the mythtv folks have one at
. Googling
"modeline howto" yields 68,600 hits which would keep you busy for a
while.

That said, I'd probably try the following:

1) Since you plan to do so anyway, go ahead and install the
proprietary nvidia driver using module-assistant. For practice, do it
from a VT console for when^W^W in case you ever screw up your X.

2) Get it set up to your panel's native resolution. Anything other
than native res or some integer sub-multiple is going to look fuzzy,
even if you use the monitor's built-in stretching.

3) Use "xvidtune -show" to get the current modeline that the nvidia
driver has so kindly figured out for you.

4) With this modeline in hand, edit your xorg.conf to set up the nv
driver as a fallback.

That is the current mode it is using. I don't know how to convert it into a

It should be on full. I thought that it may be the other way around.

At least with the nvidia driver, the nvidia-settings program can save the edid

I know nv can run 1920x1200, because I did it a year ago with a GeForce 6200
[1]. Thus, I cannot imagine it incapable of running the more common
1680x1050. Maybe you need to put a DisplaySize line in xorg.conf to get the
right size?

Re: Graphics 1920x1440, monitor 1680x1050, nv 1280x1024.

[Nuno Magalhães]

Fiddling with the monitor menu i came across this:

DIV
1280x1024
64KHz 60Hz

...that'll be useful for a modeline i guess - how can i make one?
It does have a menu for Full/4:3, i changed to 4:3., which stole
screen-area, i now have two black stripes. Even if restarting X will
give me the full res i don't think it's work it, but at least i'll be
getting somewhere.

Also, my BIOS has nothing related to the video settings, at least not
related to the resolution.

Are there any programs (for amd64) to read the EDID?

Looking at the log[0], i saw this:

#
(II) NV(0): Probing for EDID on I2C bus A...
#
(II) NV(0): I2C device "DDC:E-EDID segment register" registered at address 0x60.

#

#
(II) NV(0): NOTE: This driver cannot reconfigure the BIOS-programmed size.
#
(II) NV(0): These dimensions will be used as the panel size for mode validation.

Does the monitor have some BIOS of its own? The panel size is
obviously wrong, but it seems as though nv won't be able to change
that...

If 1280x1024 is all nv can do, i'll keep using it (in full mode, not
4:3) and i guess that wraps it up as far as having nv to fallback to.
Which list can i pester about this? I tried X's but couldn't even
subscribe.

Any chance that it's a wide screen that has an option in the menu to either
automatically or manually adjust to a standard 3:4 resolution?

I've got a samsung syncmaster and on this particular monitor at least if I set
menu->setup->image size
to auto instead of wide (so that it gives a non-stretched screen for 3:4
resolutions) the edid comes out wrong and X doesn't recognize the high
resolutions. I don't recall what is the default behavior with this monitor
though.

These look like the basic VESA resolutions. I wonder if you could
force any additional resolutions by adding custom modelines to your
xorg.conf file.

I switched to VGA to give it a try, these are the results:

DVI:
# xrandr
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024  60.0*
   1280x960   60.0
   1152x864   60.0
   1024x768   60.0
   800x60060.0 56.0
   640x48060.0

RGB:
# xrandr
Screen 0: minimum 320 x 240, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
   800x60060.0*56.0
   640x48060.0
   400x30060.0 56.0
   320x24060.0

Although, these are the drivers i have:
xserver-xorg-video-ark (don't know why i have this one anyway)
xserver-xorg-video-fbdev
xserver-xorg-video-nv
xserver-xorg-video-vmware

Would installing any other xserver-xorg-video-* make a difference?

I had it linked in the previous post's pastebin links, maybe they're
outdated by now. I've pasted Xorg.0.log [0] and xorg.conf [1] (the old
one, the new one's empty except for the mouse i tweaked).

Yeah i came across that but i'd assume DVI to be superior (i.e. more
recent, hence better) than VGA... Also, could the monitor's EDID be
reporting erroneous values?

There is a long-standing bug in the nv driver which limits it to
whatever the BIOS reports. Unfortunately it won't get fixed[1].

According to our friends over at redhat, switching to an analog VGA 
cable might help things [2].

Graphics 1920x1440, monitor 1680x1050, nv 1280x1024.

[Nuno Magalhães]

Again on X resolutions, recently dist-upgraded unstable on amd64. Are
there any X gurus out there?

- Graphics card: NVIDIA GeForce 6150 (C51PV chipset) on an Asus
M2NPV-VM, having max 1920x1440 (@75Hz) on VGA[1].
- Monitor: Asus VW222U, max 1680x1050[2].
- Driver: nv.

# xrandr
Screen 0: minimum 640x480, current 1280x1024, maximum 1280x1024

Last time i groaned about this i couldn't find documentation on nv's
supported resolutions. Also, i'm using DVI-D, not VGA (the mb has
both), and i'm not sure about what type or frequency does it
support[3]. I'd assume DVI would be better/support higher resolutions
than VGA too...

gtf is for VESA, i'd assume it's VGA-compatible? I'm not an acronym
fan... Using gtf 1680 1050 75 gave me:
  # 1680x1050 @ 75.00 Hz (GTF) hsync: 82.20 kHz; pclk: 188.07 MHz
  Modeline "1680x1050_75.00"  188.07  1680 1800 1984 2288  1050 1051
1054 1096  -HSync +Vsync

This is what i'd put somewhere in xorg.conf, right? I've tried running
dpkg-reconfigure xserver-xorg: it backs up the current xorg.conf[4] i
had edited manually and replaces it with this new minimanistic and
automagical one-section config:

(...)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
(...)
Section "Device"
Identifier  "Configured Video Device"
EndSection
(...)

Then gives me back the prompt. No questions asked. The manual one
included 1680x1050 (and a mouse tweak[5] i'll most likely need again)
but X never got there: it just refuses default modes[5] that aren't
even in xorg.conf and sticks to 1280x1024.

The Big Plan is to eventually use the nvidia driver (for compiz) but
i'd like to have a fully (i.e. to the fullest) funcional nv to
fallback to - or maybe just run different X configurations according
to my whim (or runlevel). XP does support 1680x1050 but i barely use
it (and will get rid of it soon) and it looks ugly, can't quite place
why.

Do any of you have any suggestions? Constructive criticism? Good RTFM
links? Nice coffee?

Nuno Magalhães
