Problem with X in the HURD

[German Fabregat]

Hello All.

     When I try to start the Xwindow system in my HURD box, I get the 
following message from the X server:

"nice of process failed: permision denied"  and the information that 
priority has been to -1 instead of -10 requested.

     Any hint about how to solve that?

     Best regards
     Germán Fabregat.
