Input Signal Out of Range

Jongi · #1 4th May 2008, 01:23 AM

When I try to run games, I get an error: Input signal out of range. I am running an nVidia 7800GS AGP card and this happens with both my F8 and Sidux 64-bit installs. No issues with my Debian 32-bit install. What could be the issue?

If you are using the same drivers on both distros you might try copying your xorg.conf file from the working machine to the other fedora partition. Another trick is to play with the refresh rate, ususally choosing a lower refresh rate for the monitor will allow almost all res's to show in range.

If you do a search on refresh rates and out of range you'll probably find multiple ways of doing it.

nvidia-settings gives me 60Hz as the minimum which is what the settings are running at.

Does your LCD or Monitor have an info button? Mine has one that will appear even if the monitor is out of range and I tab down using the monitor controls to a "information" setting and it tells me resolution, H. frequency, V. Frequency, Pixel Clock, etc.

It might help you figure out what refresh rate etc it's getting set to on those lower resolutions to help trouble shoot it. Also look for an online manual that specs out your monitor specs in regards to h & v frequencies and try tinkering with your xorg.conf. Also makeing sure you are running the right driver for your hardware might make a difference.

Mine did the same thing until I forced all resolutions to just use 75hz and solved for me.

Here are its specs

Should i be worried that it is labelled as CRT-0?

No. As seems usual, there is a difference in the definition of what these identifiers mean:

Quote:

Valid values for this option are "CRT" (cathode ray tube), "DFP" (digital flat panel), or "TV" (television); if using TwinView, this option may be a comma-separated list of display devices; e.g.: "CRT, CRT" or "CRT, DFP".
[...]
NOTE: anything attached to a 15 pin VGA connector is regarded by the driver as a CRT. "DFP" should only be used to refer to digital flat panels connected via a DVI port.
Default: string is NULL (the NVIDIA driver will detect the connected display devices).

In this case, 'CRT-0' is the correct identifier, from the driver's point of view....

Ah thanks. Attached is my debian 32-bit xorg.conf (xorg-debian.txt). It has no issues playing the games. I tried to replicate it as much as I could (xorg-modified.txt). But that too didn't work.

Will try the edid trick now.

EDIT: the edid trick didn't work. Anyone who can play games on their x86_64 install can you post/attach your xorg.conf?

Installed Debian 64-bit. Same issue.

***Hlingler*** · #9 10th May 2008, 05:23 AM

Jongi, do you have the 32-bit compatability package installed for that driver?

Also, your xorg.conf: according to the nvidia driver documentation:

Code:

You should also remove the following lines:

        Load  "dri"
        Load  "GLcore"

And I see what seem to be missing entries from 'Section "Files" ':

Code:

Section "Files"
        ModulePath   "/usr/lib/xorg/modules/extensions/nvidia"
        ModulePath   "/usr/lib/xorg/modules/extensions"
        ModulePath   "/usr/lib/xorg/modules"
EndSection

And:

Code:

Section "Extensions"
                Option   "Composite" "Enable"
EndSection

Is direct rendering enabled/working?

Code:

glxinfo|grep render

You want to see:

Code:

[vince@localhost ~]$ glxinfo|grep render
direct rendering: Yes
OpenGL renderer string: RIVA TNT2/PCI/SSE
[vince@localhost ~]$

If you know and have done all these things, OK, but I don't know if you have....

How do I install the 32-bit compatibility?

Yep direct rendering is enabled.

Are you using the Livna driver packages? If so, from FireWing1's tutorial:

Quote:

Additionally, if you are running a x86_64 (a 64-bit) operating system the 32bit libraries can be installed for compatibility reasons:
yum install -y xorg-x11-drv-nvidia-libs.i386

Jongi · #12 10th May 2008, 05:21 PM

It's already installed

Code:

Please attach (or post to a pastebin) a full copy of your latest Xorg.0.log file. It may show that other refresh rates are in fact available, and need to be specified in xorg.conf (or not...).

Jongi · #14 10th May 2008, 06:00 PM

Attached the log file. I've also reattached the xorg. The last one I posted was to show how I was having the same issue on debian 64-bit.

***Hlingler*** · #15 10th May 2008, 06:40 PM

I see nothing helpful in the Xorg.0.log.

It looks like you have some artefacts left over in xorg.conf from a twin-view setup, especially the "metamodes" line. Try commenting out these two lines, re-startx, see if you get more refresh rates:

# Option "TwinViewXineramaInfoOrder" "CRT-0"
# Option "metamodes" "1280x1024_75 +0+0; 1280x1024 +0+0; 1280x960 +0+0; 1152x864 +0+0; 1024x768 +0+0; 832x624 +0+0; 800x600 +0+0; 640x480 +0+0"

And comment out these two lines as well - let the probing determine:
# HorizSync 24.0 - 80.0
# VertRefresh 49.0 - 75.0

If those changes fail to help/give you more refresh rates, then I'm out of ideas.

Regards,
