To just make the message go away, ask the GTK maintainers what version of
GTK they have or will fix the bug in, and upgrade to it.   Packages depend
on distros, so you would have to ask your distro if they have packages
with that version is, once you find that out from GTK maintainers.

Replace your server or video driver with one that supports RANDR - without
knowing what OS/distro, X server & driver you use, that's the best answer
anyone can give.
