sol BadMatch Error

[We Die Young <cyclonus lavabit com>]

Greetings,

When trying to launch sol, I get the following error:

Xlib:  extension "RANDR" missing on display ":0.0".
The program 'sol' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 465 error_code 8 request_code 152 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.)

I have had this for quite a while now (several months), but never 
bothered to do anything about it.

I don't get this error when I open the game in an Xnest-server.

Kind regards,

Michel
