X won't start [FC2->FC4]

[Don Levey]

I don't see this in any of the recent messages, nor in the release notes, so
if this is an issue upgrading from FC2 (as opposed to an issue upgrading TO
FC4) I'd be happy to know.  In particular, pointers to further info would be
appreciated.

That said, the upgrade/install seemed to finish without errors.  However,
upon restart X would not start for init level 5.  I am able to login and run
via level 3 (to which it defaulted when level 5 failed).  I received errors
for both the display, and the mouse.  Running the X config program failed to
auto-detect, though the mouse was registered properly (until the next time).

The display error I seemed to get was (from /var/log/Xorg.0.log):
"**) Option "Protocol" "ImPS/2"
(**) Mouse1: Device: "/dev/mouse"
(**) Mouse1: Protocol: "ImPS/2"
(**) Option "CorePointer"
(**) Mouse1: Core Pointer
(**) Option "Device" "/dev/mouse"
(EE) xf86OpenSerial: Cannot open device /dev/mouse
	No such file or directory.
(EE) Mouse1: cannot open input device
(EE) PreInit failed for input device "Mouse1"
(II) UnloadModule: "mouse"
...
No core pointer

Fatal server error:
failed to initialize core devices"

There is indeed no file /dev/mouse.  There are two: mouse0 and mouse1.  The
wiki at X.org says to rerun the X config program, but as above this doesn't
seem to help.

At the moment I am hampered by the fact that the machine is at home and I am
at work, so that while I have command-line access I do not have physical
access until tonight.  Any suggestions on how I can test to see if the
server will start correctly, remotely, would be welcome.  Yes, I know that I
can
set Option "AllowMouseOpenFail" "1"  in my xorg.conf file - but there must
be a better way.  In case this helps, this a Microsoft Tracball mouse.

My xorg.conf file has the following for the pointer:
	Section "InputDevice"

	# Identifier and driver

	    Identifier	"Mouse1"
	    Driver "mouse"
	    Option "Protocol"   "ImPS/2"
	    Option "ZAxisMapping"   "4 5"
	    Option "Device"     "/dev/mouse"

Should I simply change the device from /dev/mouse to /dev/mouse1?  Can it
really be that simple?

I can post other logs/config files if they would be of help.  Thanks in
advance for any help,
