Dual-monitor nvidia xorg settings are reset after login

Question

I have a dual-monitor setup using the proprietary Nvidia drivers. It appears that the correct settings are used when the OS boots (it appears to be fine at the login prompt), but when I login, the settings for my dual montior are reset and the position of the second monitor is incorrect (it should be set to the right of my main monitor).

I removed xorg.conf from the /etc/X11 directory and AFAIK the only one on the system is in /usr/share/X11/xorg.conf.d/12-xorg.conf (I checked /var/log/Xorg.0.log and it says that it is using /usr/share/X11/xorg.conf.d/)

Here are the settings:

System info:

• Xubuntu 12.04
• Nvidia proprietary driver version 310.14
• X.Org X Server 1.11.3

Solution

The following fixed the issue:

• I manually upgraded the NVIDIA drivers to 319.32 (may not have been necessary)

• I modified the xorg config file MetaModeOrientation options to the following:

  Option "MetaModeOrientation" "CRT RightOf DFP"

You could try to copy that file, if it's correct, to your home directory: cp /etc/xorg.conf /home/yourusername/.xorg.conf With a dot to make it hidden.
