xfree86 4.2 on Qnx 6.3

Hi,

I’m new in xfree386.

I’ve installed and configurated xfree86 on my Qnx 6.3 station (x86).
When i exec startx it exit with this error message in the log file :
Fatal server error : could not open default font ‘fixed’
and this on the screen :
XIO: fatal IO error 254 (Connection reset by peer) on X server “:0.0” after 0 requests (0 know processed) with 0 events remaining.

What is the origin of this error and how can i correct it ?
Is xfree86 4.2 (from OpenQNX) works fine on Qnx 6.3 ?

Thanks

The XFree86 4.3 from the OpenQNX project works fine in QNX 6.3.
