Okay, just for your information , I am a complete newbie when it comes to Ubuntu. Installed it today!
Everything, so far seems great however I have stumbled upon an issue which is that the Nvidia X server is unable to keep its altered settings after a fresh boot. Why is that?!
All what was required , was to change the Digital Vibrancy setting to the max but it keeps going back to 0 after each boot.
The Ubuntu version that is used is 15.10 and the Nvidia Driver, installed is the latest and the tested version.
There maybe a solution here NVIDIA X Server Settings lost on every reboot and I tried my best to do that which was prescribed but wasn't able to resolve my issue.
Please kindly help me! Don't let Ubuntu leave a sour taste for me.
