    Mouse getting crazy, causing instability of the system

    I run 8.04, upgraded from 7.10

    For some time, the mouse is occasinally getting crazy, jumping here and there, opening windows, creating application launchers, etc. So I freqently need to reboot to get back to normal work.

    sudo pico /var/log/messages


    May 29 02:09:16 persistentstubborn-desktop kernel: [ 60.232121] psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away.
    So I did:

    mdetect -v > /Desktop/mdetect.txt

    The mouse police never sleep.
    Found the following devices:
    /dev/ttyS0
    /dev/ttyS1
    How come there are two mouse devices in the system?

    I did install virtualbox today, but the problems started occuring as from installation of the system, even before the upgrade.

    How do I fix that?

    Bump.

    Please help, the problem makes the system unusable. The mouse is jumping, switching throught the panels, opening windows, shutting down and generally doing all the nasty things.

    I guess it's something with xorg.conf, but I don't know what to do.

    Here is cat /proc/bus/input/devices for mouse

    Code:
    I: Bus=0011 Vendor=0002 Product=0005 Version=0000
    N: Name="ImPS/2 Generic Wheel Mouse"
    P: Phys=isa0060/serio1/input0
    S: Sysfs=/devices/platform/i8042/serio1/input/input7
    U: Uniq=
    H: Handlers=mouse1 event5 
    B: EV=7
    B: KEY=70000 0 0 0 0 0 0 0 0
    B: REL=103
    Here is cat /etc/X11/xorg.conf

    Code:
    Section "InputDevice"
    	Identifier	"Configured Mouse"
    	Driver		"mouse"
    	Option		"CorePointer"
    EndSection
    At least a link to a howto, or a manual, or something, please?

    Try reconfiguring your mouse to a basic PS/2 mouse using
    Code:
    sudo dpkg-reconfigure xserver-xorg
    ==OR==
    Change the above lines in xorg.conf to read:
    Code:
    Section "InputDevice"
    	Identifier	"Configured Mouse"
    	Driver		"mouse"
    	Option		"CorePointer"
    	Option		"Protocol"    "PS/2"
    	Option		"Device"      "/dev/psaux"
    EndSection
    If that doesn't work, try:
    Code:
    Section "InputDevice"
    	Identifier	"Configured Mouse"
    	Driver		"mouse"
    	Option		"CorePointer"
    	Option		"Protocol"    "IMPS/2"
    	Option		"Device"      "/dev/psaux"
    EndSection
    If neither of these work, try them each again one-by-one, but by commenting out the ' Option "CorePointer"' line.

    If any of these 4 combinations work, but you can't use the scroll button, add the below option in the section:
    Code:
    Option "ZAxis Mapping" "4 5"
    (Basic stuff, most probably you've already done this, but still...): If nothing works, please check the mouse in another system, or another mouse in this system. If it is a wireless mouse, check the batteries.

    Thank you very much, I meanwhile got another mouse and it works properly. It might be a hardware problem, but I'll try your instructrions during the day and report the results.
