Example (start R without DISPLAY from bash):
  % DISPLAY= R

  > x11("localhost:11.0")                        # this is my valid DISPLAY

  Error: Couldn't find per display information

I see this on Fedora 7 too. I suspect that the earlier report was 
thought to be Mac specific.

I was experimenting with xvfb last week and didn't see the catatrophic 
problem like that, so I tried again. Is it possible that this has 
already been fixed in R 2.6.0 ? (I am on fedora 7, x86_64 as well).
