pretty serious bug in nvidia-settings with nvidia driver and monitors and TV

[sdowney717]

Just will not keep the display for the PC as primary.
No matter what I manipulate in nvidia-settings, on a reboot, it is all gone.
I even compared xorg.conf in etc with that generated by nvidia-settings and they are the same.

To clarify the situation
This worked in 12.04.

I have a flat screen monitor
I have an old style large crt TV

I want the TV to be at the right and the LCD monitor on the left
I make changes in nvidia-settings and save to xorg.conf.

On a reboot, the crt TV always comes up on the left and the LCD monitor on the right.

I have also manually copied the xorg.conf that nvidia-settings generates into the xorg.conf file.

Either ubuntu is not loading xorg.conf or it is not being made properly by nvidia-settings.

xorg.conf looks different, seems to be missing the DFP-0 monitor settings?

[sdowney717]

With nvidia-settings, I moved the tv over to left
and previewing shows it does generate a different xorg.conf

So I dont know enough to say what is wrong.
Ideas?
In the Monitor section, I only see the TV-0, not DFP-0

On reboot, TV always is on the left side.
So to fix, I unpluged the cable!
Aynyone have a better fix?

[sdowney717]

I think xorg.cong is ignored
I made some bigger changes and get no response.

Is this due to beta status?

Well apparently Display program in Ubuntu settings in Ubuntu overrides Nvidia-settings display orientation position.

Is that to be expected?

[23dornot23d]

The main problem is that the programmers have not identified what is creating the xorg.conf .......

A simple commented line in the xorg.conf showing what has created it would help to identify what is creating
these automatically placed configs into place. ( xorg.conf ) was always a help - but when the system keeps creating it wrong then it soon becomes a pain.

( a few days back I identified that nvidia-prime was one culprit for my own setup ......... if you have this installed - it may be worth removing it to see if the problem still exists ........... seems it is only required for optimus setups ......... which is ( intel and nvidia combined in laptops for battery/power saving which is what I have - but I think you have a desktop machine with a nvidia 8400 gs ) so that file is not needed if it is there.


Seems you have another thread on a similar subject and solved it here

Or do a test and if nvidia driver is installed with nvidia-settings, then use the xorg.conf not the monitor xml file.

[GDPR-ohya4wai4eiJ]

Am I the only wondering why nvidia-settings has created his xorg.conf while it shouldn't be responsible for doing this? Normally nvidia-xconfig is creating the xorg.conf.

He is probably using the Save to X Configuration File button.
