Saved Nvidia Xorg.conf settings lost and revert on log out or reboot

[ineuw]

When issuing these commands interactively through the terminal they work fine. But, when I log out or reboot the settings revert to the original 1280 x 720. How can I make these settings "stick" permanently?

xrandr --newmode "1408x792_60.00" 90.75 1408 1480 1624 1840 792 795 800 823 -hsync +vsync
xrandr --addmode HDMI-0 "1408x792_60.00"
xrandr --output HDMI-0 --mode "1408x792_60.00"

I have a different card (AMD), but I found that when configuring it and even inspecting xorg.conf to make sure it stuck - the file was getting renamed when I rebooted, stopping the system from using it.
I renamed it back to xorg.conf and rebooted again and all was well.

For some reason the date was getting appended to the end of the file name without saving a properly named copy as well. I think it is a broken back-up procedure?
ANyway, different card and driver so YMMV.

What does the actual xorg.conf say?

What does the actual xorg.conf say?

Thanks maxinstuff2. It did create a file named xorg.conf.backup I renamed it but it ignored it.

deadflowr; below is my current xorg.conf:
This option line in the Device section, I copied from another configuration I found on the web. Without it,it won't boot into GUI and I end up in command line mode, Have to delete the file, or edit it with vi.
Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck,

This line in the Monitor section is generated by the cvt command: cvt 1408 792 60
ModeLine "1408x792_60.00" 90.75 1408 1480 1624 1840 792 795 800 823 -hsync +vsync

Regardless of what I do, after login/reboot, it reverts to 1280x/720. in an earlier post, I was so confident that I resolved the issue that I wrote a post with instructions, and now I feel like a fool. http://ubuntuforums.org/showthread.php?t=2241643&p=13119484#post13119484

I would think the next step would be to look at the log file(s)
Look at the log file in /var/log/xorg.0.log.

You might post it, probably better to post the whole thing to pastebinit
https://help.ubuntu.com/community/Pastebinit

Since you never know how fat any log file might be, and paste is a better place to post large files, rather than here in the forums.

Don't know how much it will help, but the log should give a general clue as to what's going on...

Maybe, try changing the metamode line to 1408x792+0+0 , omitting the refresh rate 60.00.
See if that changes anything.

[ineuw]

If you look at the Xorg.conf, there is a negated line as follows
# Removed Option "metamodes" "1408x792 +0+0; 1408x792 +0+0"

I also posted on the Nvidia forum but got no response. Where would be the best place to deal with this issue?

I will try again as you recommend. In the meantime - reading the article in Wikipedia on EDID, I installed this program and this was the result

[QUOTE=deadflowr;Maybe, try changing the metamode line to 1408x792+0+0 , omitting the refresh rate 60.00./QUOTE]

Well I tried it but no change, so this is what I did since I knew all the parameters. I edited the Xorg.conf manually and cobbled together the following file:
Whenever I log out & in, it is stlil the old setting but, at least I can the list contains 148x792 and I can select it for the session. It's not a solution but I can get some work done.
