I've been having enough odd problems with my Ubuntu MATE 16.04 machine that I decided to move back to my Ubuntu 14.04 machine until I can resolve them, possibly at the next clinic.
The X11 issue I'm having is on the 14.04 machine. When I boot up, I get a mostly normal looking right hand monitor, but a left hand monitor that shows some of the right hand background image, and the left hand image moved off to the left so that the menu is hidden. If I slide the mouse over beyond the left edge of the screen, things look normal. I tried running gksudo nvidia-settings. When I clicked on the apply button I got this error message: __________________________ rsteff@Enu-1:~$ gksudo nvidia-settings 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 872 error_code 2 request_code 157 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.) rsteff@Enu-1:~$ ______________________________ Any ideas on what's going on?
