Problems with 1.0-9631 on Geforce4 420 Go

[cut]

Hi,

I recently installed the Nvidia Legacy Driver 1.0-9631 for Linux x86 on my Notebook (Toshiba Satellite 2410-404, running Ubuntu 6.10 Edgy Eft. The graphics card is a Geforce4 420 Go 32MB, and I am using no external monitor.

After adding Option "ConnectedMonitor" "DFP" to my xorg.conf I had no more black screen, and with Option "ModeValidation" "DFP-0: NoDFPNativeResolutionCheck" I got rid of the surrounding black areas (it's nearly fullscreen now).

Still I've got some problems I couldn't solve on my own:

1. The black bar on the right won't go away
2. I can't get a resolution higher than 800x600

Option "ExactModeTimingsDVI" "TRUE" and Option "UseEDID" "FALSE" which I found as a solution in resembling threads are producing a black screen (sometimes with backlight on).
Also I couldn't find/produce any modelines which would allow me to use this options or increase the resolution.

I hope someone can help me with this problem(s).
Thanks in advance.

I have the same problem along with many others it seems. I'm using a Toshiba 1415-s173 with the geforce 4 go chipset. I wish someone would fix this blackbar problem............. Maybe we should start a list with fixes for each laptop model and os version?

Hello,

look what resolution your EDID reports.

I run a Toshiba Satellite Pro 6100 with Debian Sarge and XOrg 6.9 from bpo.
The EDID tells that the native resolution of the display would be 969x768 instead of 1024x768.
Older NVIDIA drivers had "IgnoreEDID" to solve this but the new ones not :-(
So I tried and tried for hours (nearly every option I could change in xorg.conf) always ending up in black screens or black borders.
Finally found that solution:

I saved the EDID by nvidia-settings to a file and edited this.
The horizontal resolution is safed in the bytes with the offset 56(Hex:38) and 58 (the upper four bits) (Hex:3A)
In the original EDIT these bytes were C9 and 31 (0x3C9 = 969)
I changed them to 00 and 41 (0x400 = 1024).
Then I used the Option "CustomEDID" "/path/to/patched/EDID.file" like described in Appendix D of the documentation.

This works for me.

Further information about the structure of the EDID you will find at
http://en.wikipedia.org/wiki/EDID#EDID_1.1_data_format

HTH!
Best Regards,
Thomas.

Same laptop, same problem. Please post if any of the solutions mentioned work. I've been trying, but had to go back to NV since that black bar and 800*640 sucks.

Thomas,

Could you post your EDID file so I can try it? I can't figure out how to edit the saved file (garbled characters are all that appear).

I am also having the same problem but with a Geforce4 440 Go in a Dell Inspiron 8200. I'm not quite sure how or where I can get the EDID information from nvidia-settings since it won't run without the display working. Any help would be appreciated.

------------
It seems adding the line: Option "UseDisplayDevice" "DFP"
has fixed the problem.
Found the answer here: http://www.nvnews.net/vbulletin/showthread.php?t=77433

Hallo,

just run nvidia-settings from the running X (the lower resolution or the black stripe do not effect the result, because the EDID is burned into the Hardware).

You find information about the structure of the EDID in the English Wikipedia (just look for EDID). It's a binary with a size of 256 bytes.

Viele Grüße,
Thomas.

Thanks orlo11 it worked great!

as a recap of what I had to do to get this to work:

System:

Toshiba Satellite 1415-s173
Debian Etch RC2 / Xfce4
Vanilla Kernel 2.6.20.4 + minor patches
Nvidia 1.0-9631

After installing everything, including the nvidia driver, I edited xorg.conf and added/changed the following under "section device:"

Driver "nvidia" #This is changed from Driver "nv"
Option "UseDisplayDevice" "DFP"

I started X and used nvidia-settings to get the edid info as stated above in orlo11's post.
Personally I used ghex to edit the file and saved it as edid.bin in the xorg.conf directory.
With ghex I was able to open the file and use goto to locate offset 56 &58, this made it snap to do.

Then I edited xorg.conf again and added, under section device, this:

Option "CustomEDID" "DFP-0:/etc/X11/edid.bin"

restartx and it works great!!!!!!!!!
Thank you again orlo11, I had been working on this off and on for some months and tried all the other hints and tricks with no luck, this worked great. I did have to add DFP-0 in the customedid line for my laptop.

Hi all,

Perhaps not all of us are well-acquainted with all this edid-saving and hex-editing, so I am including herein a patched edid.bin that works for the Toshiba Satellite 1415-S173, and probably for the whole 14XX series.

none of these solutions work for me. i have this:

(EE) NVIDIA(0): Failed to load the NVIDIA kernel module!
(EE) NVIDIA(0):  *** Aborting ***
(II) UnloadModule: "nvidia"
(II) UnloadModule: "ramdac"
(II) UnloadModule: "fb"
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

any suggestion? tnx

[marioquark]

have i to trash my toshiba?!

solved: thanx to hyperair from ubuntuforums.

Which instructions did you follow? If you by chance installed nvidia-glx-new and then replaced it with nvidia-glx it may have left a file (/lib/linux-restricted-modules/.nvidia_new_installed). Delete that file (sudo rm /lib/linux-restricted-modules/.nvidia_new_installed). Then restart your system. It should work I think.
