I have this same problem in both 13.10 and 14.04. Whenever I reboot the computer, the changed settings such as gmma value and brightness etc that should stored in nvidia-settings-rc cannot be reloaded and the screen will automatically reset to hardware default. There is no workaround if you are using drivers 319 and 331- at least I cannot find one. This is a bug that contain in the nvidia driver for quite a long time without solving while I cannot see any action from nvidia to solve it . The only way to work around the situation is using 304 driver. But it doesn't mean that the problem is solved. After rebooting, you still get the hardware default settings again. But if you run nvida-settings, the configuration file will immediately reloaded and change to your what you have set. Then you might think of starting nividia-settings automatically when you reboot the machine and kill the program automatically. The way I do it is
1. run startup 2. add to startup for 2 action, the first one is: A. give the start up a name say "1-Nvidia X Server-settings". Start with 1- is for convenience to quencing the actions properly on the list. B. sh -c '/usr/bin/nvidia-settings' for the command line C. Make a comment whatever you want. Then save and quit. 3. Once you retart the program, the added startup command will execute to load the preferred settings. 4. But at the same time, the nvidia program will pop up for every reboot . You might have to kill it manually. If you want to automate the kill, add the following command after the aforesaid command in 2.. A. give a name say 2-kill Nvidia. Start with '2-' make it just quence after the above nvidia-settings command. B. command line field should write as ---- sh -c 'sleep 2 && killall nvidia-settings' . Please note that the addition action sleep 2 is aimed to delay the killall command for 2 second since you need sufficient time to let nvidia-settings to run. Reload might be fail without this. C. Make whatever comment for the third line. 5. Reboot and your problem should be solved now. Moreover, if anyone can work around the problem with version 331 or 319, I would much like to know since 304's game capability is quite low. Also 'Save to X Configuration File' button seems affect mainly to the monitor's resolution and orientation etc and make no help to the situation. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1241421 Title: Can't save nvidia settings in 13.10 Status in “nvidia-graphics-drivers” package in Ubuntu: Confirmed Bug description: As I said in title I have problems with saving settings in nvidia- settings dialog.
