Description Chris Caudle 2007-03-21 02:48:00 UTC
Description of problem:PS/2 mouse is not detected by X after updating to 

Version-Release number of selected component (if applicable):

How reproducible: every boot (only one machine to check, though)

Steps to Reproduce:
1.Update kernel to kernel-2.6.20-1.2925.fc6
Actual results:
Mouse pointer is not operational in runlevel 5.

Expected results:
Mouse is detected and operational

Additional info:
PS/2 connected Logitech Trackman Marble trackball, via Belkin "Flip" KVM switch.
Mouse is detected and works properly when running kernel-2.6.19-1.2911.6.5.fc6.
Mouse works properly in console mode (gpm?).  Even when running
kernel-2.6.20-1.2925.fc6, if I switch to a different virtual console (i.e. not
running X), the mouse pointer moves as expected, just no mouse in X.

X86_64 architecture
gpm.x86_64 (i386 version also installed, but my assumption is that the x86_64
version is running)

Grep'ed for serio and mouse in dmesg output:
serio: i8042 KBD port at 0x60,0x64 irq 1
serio: i8042 AUX port at 0x60,0x64 irq 12

mice: PS/2 mouse device common for all mice
logips2pp: Detected unknown logitech mouse model 72

This is the result of search for "mouse" in Xorg.0.log:
(**) Option "Protocol" "PS/2"
(**) Mouse0: Device: "/dev/input/mouse0"
(**) Mouse0: Protocol: "PS/2"
(**) Option "CorePointer"
(**) Mouse0: Core Pointer
(**) Option "Device" "/dev/input/mouse0"
(**) Option "Buttons" "3"
(**) Option "Emulate3Buttons" "False"
(**) Mouse0: ZAxisMapping: buttons 4 and 5
(**) Mouse0: Buttons: 9
(II) XINPUT: Adding extended input device "Mouse0" (type: MOUSE)
(II) XINPUT: Adding extended input device "Keyboard0" (type: KEYBOARD)
(II) Mouse0: ps2EnableDataReporting: succeeded

Hardware is Tyan S3992 motherboard with Opterons, keyboard and mouse connected
through Belkin KVM switch.

Comment 1 Chuck Ebbert 2007-03-21 18:36:01 UTC
The mouse should really be on /dev/input/mice.

Edit /etc/X11/xorg.conf and change every occurence of
/dev/input/mouse0 to /dev/input/mice, then start/restart X.

Comment 2 Chris Caudle 2007-03-22 00:24:37 UTC
You are correct, changing input to /dev/input/mice corrected my problem.
I suppose /dev/input/mouse0 was aliased to /dev/input/mice somehow in older kernels.
