as I checked this, it's the same as drops-x.rd (comparing two files with cmp 
gives no difference) from DROPS/TUD:OS demo CD (I downloaded it about 1

I enabled X server stub in L4Linux configuration (a checkbox "Support for X 
Window System driver" is enabled). And nitovlwm server is started. What could
