xfce4 & X11 problem with twinview monitors

smkh · 05-27-2013, 12:10 AM

Hello every body!
I am using Linux Mint 14 with xfce4 as a desktop manager.
I installed nvidia driver and work with two monitor as a one screen (TwinView configuration).
recently I have a strange problem with this:
When I am logging out and log in again the TwinView doesn't work as I expected and I must reconfigure the nvidia driver through nvidia-settings application.
I created another user and this new user does not have this problem so this problem is user related and I think xfce4 does not save something.

any help appreciated.

Here is my /etc/X11/xorg.conf:

Code:

Hi, make sure that the users config file "/home/glenn/.nvidia-settings-rc" is write-able (possibly group write able)

Most of your settings are saved there.

Just a guess.

The .nvidia-settings-rc is writable by my user:

Code:

meysam@meysam-pc ~ $ ls -l .nvidia-settings-rc 
-rw-r--r-- 1 meysam users 1615 May 29 08:26 .nvidia-settings-rc

I think it got more to do with xfce4 not initialising the xconfig with the user login.
That's all I got.

Your xorg.conf file looks fine. (I run 2 monitors with nvidia.)
