NVIDIA Configuratioin does not persist; low resolution comes back after reboot.

Asked by Francis Mosse

Recently we played with the NVDIA setup and since then I've had problems with the resolution. When I login the screen shows a resolution lower than ususal. I need 1920x1200. I've made many attempts to adjust and save the configuration. When I adjust the resolution it works fine and apparently I can save it.

The only problem is that after I reboot it will always start off with the lower resolution.

Yes, I did adjust the configuration as root: gksudo nvidia-settings and saved it to /etc/X11/xorg.conf

I've also checked the driver (System/Administration/Hardware Drivers) and I'm up to date: NVIDIA accelerated graphics driver (version 180).

Here is my /etc/X11/xorg.conf file below. Let me know what you think. Thanks!

Hello, Francis. :-)

Run "gksudo gedit /etc/X11/xorg.conf"

and in your "Screen" section, under 'Option "TwinView" "0"', where it says 'Option "metamodes..."

make it read

Option "metamodes" "1920x1200 +0+0; nvidia-auto-select +0+0"

and save.

See if that helps. :-)

Change the resolution in the display manager then it should be fine.
system>preferences>display
Say no to the dialogue that appears. Then simply select the resolution that it should be.

Hope that helps
Shane

And I'd like to add: thanks for being smart. We often times overlook the simplest way; we forget that simple also means powerful. Well done!
