FreeGlut does not work in ghci

I wrote a small program using the "Glut"

import Graphics.Rendering.OpenGL 
import Graphics.UI.GLUT
main = do 
  (progname, _) <- getArgsAndInitialize
  createWindow "Hello World"
  mainLoop

The program, compiled by GHC runs fine (ghc --make t.hs), but when I try to run the program from ghci, ghci crashes with message:

freeglut (<interactive>):  ERROR:  Internal error 
<FBConfig with necessary capabilities not found> in function fgOpenWindow
  X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  4 (X_DestroyWindow)
  Resource id in failed request:  0x0
  Serial number of failed request:  33
  Current serial number in output stream:  36

Is it possible to run a Glut program from ghci?

In my experience this seems to be related to using the Nvidia drivers in Linux. My experience with this particular problem is limited to Ubuntu 11.04, in which I can remedy this error by uninstalling the proprietary drivers.
