I installed 16.04 today and I wanted to increase the color liveliness and tweak some vertical sync and texture quality settings, but every time I reboot the settings get reverted back.

Every guide and forum I looked around was way too complicated and didn't help me in solving my problem that seems quite simple for someone who has experience with the Linux and Nvidia GPUs.

I have changed settings from a lot of the sections and I want all of the saved every time I restart.

A quick step by step guide on what I should do would be highly appreciated.

Bring up your terminal, then run nvidia-settings as root:

sudo nvidia-settings

After you've configured your settings, click on X Server Display Configuration, then click on the Save to X Configuration File button, enter /etc/X11/xorg.conf in the textbox, make sure Merge with existing file is unchecked, then click the Save button.

Had same problem. Above solution did not work for me. Nvidia settings has a "Show Preview" button when saving. Use this to copy-paste the contents into the /etc/X11/xorg.conf file manually.

I tried the above solution again just now, just to double check, and every time it tells me:

Unable to open X config file '/etc/X11/xorg.conf for writing.

Even told me the same for my home directory and root's home directory.
