nvidia tool cannot write to any config file

[stuartmacg]

I used the nvidia tool to set up dual head display. It worked fine, but could not write to /etc/X11/xorg.conf. It could in face not write to any file name anywhere.

I solved my problem by displaying its output and cut and pasting to an editor, but it looks like the tool is not working properly.

Re: nvidia tool cannot write to any config file

you need to run the tool with kdesudo run the command

kdesudo nvidia-settings

check you menu entry (rt click on the k choose menu editor) and correct it so the menu entry works the same way . if you don't get a password prompt then its not running as root, if its not running as root it can not save to the /etc/X11/xorg.conf file

That fixed it, thanks.

When run from the menu it could not write its settings to any file - even in my home directory.

Previously on (non k) Ubuntu you got a password request when you started it from the menu - as with gparted. That seems to be a more friendly approach don't you think?

Re: nvidia tool cannot write to any config file

The intent of nvidia-settings is to allow individual users to have there own setups. It's supposed to save a file in your home .nvidia-settings-rc when invoked as a regular user.

You can force the behavior you're suggesting by adding kdesudo to the menu item. Personally, I think they should program a switch in the program itself allowing root access when desired, thus giving us both options.
