1) As Nvidia Customer Care team suggested, I manually installed driver 304.123 (instructions at http://askubuntu.com/questions/451221/ubuntu-14-04-install-nvidia-driver, answer nº 23). 2) Running gksudo nvidia-settings enabled me to change my screen resolution, but my nettings were not being preserved after rebooting my machine. 3) I went to System Settings --> Monitors, and changed my screen resolution from there. My new settings were preserved after rebooting this time.
It seems driver 304.123 solves the issue, but it's not available for Trusty yet. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-settings in Ubuntu. https://bugs.launchpad.net/bugs/1388430 Title: nvidia-settings closes when pressing 'Apply' button, but changes aren't applied Status in “nvidia-settings” package in Ubuntu: New Bug description: 1. I recently did a fresh install of Ubuntu 14.04 (64 bits) on my machine, which has an Nvidia GeForce 6200 graphics card. When I try to change the screen resolution, changes are not being applied and nvidia-settings is closing when I press the 'Apply' button. 2. I run nvidia-settings in a terminal, and I got the following error message after pressing the 'Apply' button (see the attached file): The program 'nvidia-settings' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 528 error_code 2 request_code 158 minor_code 25) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) 3. This seems to be a duplicate of Bug #1273652. 4. I contacted Nvidia custom care support, and they suggested me to try the latest driver version (304.123). Unfortunately, when I checked "nvidia-graphics-drivers-304" at Launchpad, I found it's only available for Utopic, Precise, and Vivid (indeed, it doesn't appear in my Additional Drivers wizard). If you help me to install version 304.123 on my system, I'll give Nvidia Linux maintainers all the feedback they are requesting from me, and I'll be in a better condition to colaborate with you to solve this issue (installation instructions provided by Nvidia website are hard for me to follow). Feel free to e-mail me if you think I can help in any way. 5.

System settings: OS version: Ubuntu 14.04 LTS (64 bits) Nvidia driver version: 304.117 nvidia-settings version: 331.20-0ubuntu8 P.S: apparently, this is not the first time a bug like this affects nvidia-settings on Ubuntu. If you read the comments at the second and third links in point 5 (above), there is people who solved the issue after they installed an nvidia-settings package which version number matches the driver one (or vice-versa).
