Problems with installing RTlinux 2.0

["F. de Beer" <f.debeer-at-wxs.nl>]

List,

When I install RTlinux 2.0 on RH 6.1 I get after a cold reboot a fatal error
from the x-window server:

Can't connect: errno = 111
Failed to set default font path 'unix/:-1'
Fatal server error:
could not open default font 'fixed'

For me it was the first time that I installed RTlinux 2.0 so I did it again
but with the same result.
What is wrong and what needs to done?
