Question ps/2 mouse with strange behaviour in Fedora 3


My PS/2 mouse is behaving oddly...

Under windoze it works fine.
But when I start Fedora (Core 3) I don't get any response to the mouse movement/clicks.
It already worked well, but got like this when I had to boot the PC without the mouse attached...
In /etc/sysconfig/mouse I have

FULLNAME="Generic - Wheel Mouse (PS/2)"

and now /etc/X11/xorg.conf

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

I tried "cat /dev/input/mice" and then moved the mouse around but got no data on screen.
The same with /dev/mice, /dev/mouse0, /dev/input/mouse0. I don't have /dev/psaux on my system.

Now the funny thing...
I tried to disconnect the mouse from the ps2 port and then connect the keyboard to the mouse's (not Moses ) port and press a few random keys. Next I connect the mouse and keyboard to the correct ports.
And there you have it: the mouse now works!!!

After this I tried again "cat /dev/input/mouse", moved the mouse and I got data appearing on screen as I moved the mouse around.
The same with /dev/mice /dev/input/mouse0 and /dev/mouse0.

Maybe something is missing to initialize the ps/2 port???
In the line MOUSETYPE="IMPS2" should it be "IMPS/2" instead?
I'm not sure about what might cause this issue. Some help would be truly appreciated.

The only difference I see on my FC2 box is that the MOUSETYPE="imps2"
(imps2 is lowercase) not "IMPS2". Otherwise, the settings look the same.

Thumbs up

Oh well...

I got it to work again!
It seems the problem was in the BIOS. My "PS/2 mouse function" was set to "Enabled". I don't know how it got like this but I supose that it might have been because I made changes to the hardware and the after restarting without the mouse attached it messed with the mouse settings...
Setting "PS/2 Mouse Function" to "auto" solved the problem.

Thank you Thank you Thank you!!!
I didn't see this thread until just now, but I poked into my BIOS to see if I had the same problem.
I didn't see any PS/2 mouse info, but it mentioned USB Legacy Mouse support, so I disabled it, and now, instead of jumping around like it's on crack, my mouse just slows down when the processor's under load.
I'll be linking to here from the other thread.
