Resolution reset on reboot with NVidia video card

OpenSUSE 10.3

I’ve changed my screen resolution thru the NVidia utility “nvidia-settings” to 1920x1080, I’ve saved the Xorg configuration file, and it works fine. Though, when I reboot my computer, the resolution is 1280x960.

Question: how can I make my resolution fixed to 1920x1080 when I reboot my PC?

Here there is my xorg.conf file:

# nvidia-settings: X configuration file generated by nvidia-settings

Try to save it again as root same as you did last time but choose not to merge it with the existing configuration. In case you wonder what that is in the prompt before you click save it is there where you can just tick/untick it.

Thank you conram.
I’ve tried your solution but it doesn’t function (saving the xorg.conf file by the nvidia-settings utility without merging content): the problem persists.

I missed to say that, when PC reboots, at the login form the resolution is 1920x1080 but as soon as I’m logged in the resolution will change to 1280x960. More, the xorg.conf is unchanged and is the same that I’ve saved by the nvidia-settings.

It seems that the problem is in the module that reads the xorg.conf just after the logging operation tooks effect. Maybe a problem of GNome?

What was the original resolution before you changed it.
Did you check if the resolutio you are trying to use is supported?

5

Yes, the resolution 1920x1080 is supported. At the login form, the resolution IS 1920x1080, but as soon as I insert username, password and login, the resolution change to 1280x960. So I must enter in terminal, launch nvidia-settings utility, select 1920x1080 resolution then click on Apply and the resolution change to 1920x1080.

In the nvidia-settings did you use your user or as su. If using the user it will not stick you have to be su to be able to save it.
