I just installed Fedora core 1 and the available updates. Im using a logitech wireless PS/2 mouse. After booting the mouse pointer does not respond to the mouse. Only After a switch to a virtual console and back to X again does the mouse start to work (CTRL-ALT-F1 ALT-F1). Any one have any ideas how I can fix this?

Here is the mouse sections from my X config file. These are the way Fedora generated them.

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "no"
EndSection

Section "InputDevice"
# If the normal CorePointer mouse is not a USB mouse then
# this input device can be used in AlwaysCore mode to let you
# also use USB mice at the same time.
Identifier "DevInputMice"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "no"
EndSection

I'm using the same type of mouse (the blue Logitech optical), but without the optional PS/2 adapter. You may want to verify the USB, PS/2, hot pluggable device, etc settings in your kernel. There does seems to be some slight bugginess with the mouse though. Sometimes, the cursor will freeze up on my box, but just disconnecting/reconnecting the mouse will fix it.

try changing IMPS/2 to MouseManPlusPS/2 in the first block (with the mouse0 indentifier)
I believe I have the same mouse as you do, and this is what my XF86Config file has
