I'm having the same problem too. This is recent, so I suspected an update may be the culprit. I have tried reverting to a previous version of nvidia driver, but that made no difference. Error message is substantially the same-
ERROR: Error querying target relations The program 'nvidia-settings' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 82 error_code 1 request_code 154 minor_code 29) (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.) -- 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/1273652 Title: "apply" of multi-monitor setting results in crash Status in “nvidia-settings” package in Ubuntu: Incomplete Bug description: After the recent update of nvidia settings, I am not able to apply new monitor setting via nvidia settings anymore. After configuration of "X Server Display Configuration" hit hit the "apply" button and then the program simply quit. A workaround is to click on "Save to X Configuration file" and restart the computer.
