Xlib: extension "RANDR" missing on display ":0" error

So I was trying to run a simple code for a contour plot using the Spyder Python IDE and this error popped up:

Xlib:  extension "RANDR" missing on display ":0"

Through Google, I found that the solution was to install this package from the USC:


I ran the code again, the error message was gone, and it generated my plot.

Found solution here:


  1. I could not find gtk2-engines-pixbuf. Only gtk2-engines-devel-2.18.4-5.el6.x86_64. Did not work. Still get:
    gedit dec&
    [1] 16658
    [sarah@heather bdata]$ Xlib: extension "RANDR" missing on display "".

  2. Disable xinerama and is going to go away. Easiest way to do it is though xorg.conf

  3. I have gtk2-engines-pixbuf to 'newest version'. Does this mean I need to downgrade or use a different source?
