[mythtv-users] XWindows is starting up before /dev/fb0 is ready(Help!!!)

[Karm may]

When my Myth box boots up it is suppose to display X
on the PVR-350 TV-Out.  The only thing I get is a
black screen with a white cursor displaying on the TV.
 When I type on the keyboard I don't see any text on
the TV but the cursor moves.  If I continue to type my
user name and password and then type startx then KDE
starts up on the TV.  This is not convenient,
especially the typing blindly ;-)

The messages.log has "kdm[3927]: Display :0 cannot be
opened" which might be of interest:

===========
Also in the X86Free.log
(II) Reloading
/usr/X11R6/lib/modules/linux/libfbdevhw.a
(EE) open /dev/fb0: No such device
(EE) No devices detected.

Fatal server error:
no screens found

***********************
Just looking at this it is looks like X is starting
before /dev/fb0 is available, but I am no expert on
this matter!!

Any ideas???????

P.S.  I have changed /etc/rc5.d/S56xinetd to
etc/rc5.d/S98xinetd.  This change does bring up
XWindows on the TV but it is not reliable.  Sometime I
still get the black screen with the white cursor on
the TV.
