Comment 70 for bug 197153

I still have this issue (nvidia driver) and cannot start gnome-settings-daemon with xrandr enabled (8.04 fully updated). So either i am experiencing another bug or this issue is still there.

The program 'gnome-settings-daemon' 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 5739 error_code 1 request_code 151 minor_code 6)
  (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.)
