[sane-devel] Canon Pixma MX-925 on Ubuntu 12.04

Is no one able to help me have xsane work on Ubuntu 12.04?
This is what I get in terminal when trying to run Xsane in 12.04 Ubuntu
[14.04 works fine]:
:~$ xsane
Xlib:  extension "RANDR" missing on display ":0.0".
The program 'xsane' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 17713 error_code 8 request_code 155 minor_code 5)
  (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.)

Any suggestions of what is wrong or how to correct or test further? Thanks
