My xorg.conf is not working. It needs to be 1440x900 but is 800x600

[Farmer of Bricks]

It's rather quite simple. Neither xfix nor the nvidia autoconfig utilities create a working xorg.conf. I am using the Nvidia driver version 96, the one recommended by "Hardware Drivers," the driver manager for KDE4. Until this problem is fixed, I'm stuck with a nice, big, 17" 800x600 screen.
Thank you in advance for your help.

Here are the current relevant errors thrown up in /var/log/Xorg.0.log:

You may have already tried it but xorg server detect my monitor just fine and I only need a real basic xorg.conf:

Once again, autoconfig utilities are not working. The EDID (http://http://en.wikipedia.org/wiki/Extended_display_identification_data) data is not being passed on to the configurators for some reason, so I am having to build an xorg.conf by hand.
after a bit of Googling, I discovered a command that will list my EDID data.

What I would very much appreciate is someone looking at the xorg.conf I posted previously and telling me what I am doing wrong.
Thank you for your kelp.

[Gen2ly]

Xorg works with udev to autodetect alot of devices (if not all), Farmer. But some do need to create a xorg.conf. A couple things: are your Hsync and Vsync values in range with your monitor? Usually you will get a "display is out of range" (or something like that) error, but that can depend on your monitor; and how did you calculate your modelines? gft is probably your best bet (if you didn't use it before):


gtf horiz_res vert_res refresh_rate

[Farmer of Bricks]

I've been using cvt, but I see that they do return different values.

blk@blackbox:~$ cvt 1440 900
# 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz

-returning to computer later-

O.o
I just discovered that modelines go under Section "Monitor", not Section "Modes". That's the kind of help I'm looking for. Thank you, Xorg Wiki! (http://www.x.org/wiki/FAQVideoModes#head-d174fd476064edf62ed05d71d8a91b3dc4307324) I'll see if this works when I log in tomorrow.

Narga narga narga.

Still in 800x600. /var/log/Xorg.0.log says:

Bump.
This is getting to the point where I'm getting used to the small screen, something that I find kind of scarey.
If this isn't fixed by the time 9.10 comes out, I will definitely do a clean install, but I'd rather like to have my 1440x900 back.

The problem, now that I've started X with startx -- -logverbose 6, is that my EDID value for the Pixelclock is set to 0.0.

How do I change the EDID Pixelclock setting?

A sample:

(II) NVIDIA(0): Validating Mode "1440x900":
(II) NVIDIA(0): 1440 x 900 @ 60 Hz
(II) NVIDIA(0): Mode Source: X Server
(II) NVIDIA(0): Pixel Clock : 106.50 MHz
(II) NVIDIA(0): HRes, HSyncStart : 1440, 1520
(II) NVIDIA(0): HSyncEnd, HTotal : 1672, 1904
(II) NVIDIA(0): VRes, VSyncStart : 900, 903
(II) NVIDIA(0): VSyncEnd, VTotal : 909, 934
(II) NVIDIA(0): H/V Polarity : -/+
(WW) NVIDIA(0): Mode is rejected: PixelClock (106.5 MHz) too high for EDID
(WW) NVIDIA(0): (EDID Max: 0.0 MHz).


The entire, extremely verbose /var/log/Xorg/0/log can be found at http://pastebin.ca/1569049.

[Farmer of Bricks]

I finally fixed it about a month ago with a custom xorg.conf, putting the " Option "NoEDIDModes" "true" " in its correct spot, under Device.

See here:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce4 MX 4000"
Option "UseEDIDFreqs" "false"
Option "ModeValidation" "CRT-0: NoMaxPClkCheck, NoEdidMaxPClkCheck, AllowNon60HzDFPModes"
Option "NoEDIDModes" "true"

EndSection


So, for those of you who come across this problem in your use, try the following:


Section "Device"
Identifier "Device0"
Option "NoEDIDModes" "true"

EndSection
