Xlib: extension "RANDR" missing on display "/tmp/launch-zP0Uvj/:0".

[Jeremy Huddleston]

It definitely is just a warning.  It occurs whenever an app tries to  
query the RANDR extension.  It notices that the extension is missing  
and disables whatever optional support it would've had for that  
extension.  gtk2 based applications will do this every time they  
start... probably any app that uses a toolkit higher level than libXt,  
libXaw, or motif will omit such a message.
