    Losing Control Of The Mouse

    Hi;

    I installed Knoppix 3.1 to the hard drive of a new computer.

    Its a custom built machine with a Pentium 4 CPU that came with an "Intel
    Desktop Board d845PESV" motherboard ( also the name of the chipset on the
    mother board ).


    When I log out of a desktop/window manager(icewm,gnome,kde) and return to
    a gui lilo dialog I lose control of the mouse.


    No matter how much I move my mouse I can't make the caret/cursor/pointer
    on the screen move.

    I can temporarily fix this problem by rebooting X windows by pressing
    Ctrl-Alt-Backspace.

    I would like to fix this problem permanently.

    Any ideas on how to do this?

    Thanks in advance

    Steve

    Is it a PS/2 mouse or USB mouse? I suspect USB; what brand? One of the problems with inexpensive mice (and even some expensive ones, I suspect) is that they are only tested under Windows. There are hardware timing issues with some peripherals -- remember, a USB mouse has a microcontroller in it and has to "shake hands" with the PC hardware on a continuing basis. It may well be "losing its grip" while in command-line interface (CLI) mode. This has happened to me.

    Okay, here is where I show my hardware ignorance .

    If by "USB mouse" you mean having tiny little holes for tiny little rods at the connection point, then yes, it is a "usb mouse".

    It is a 5 year old microsoft mouse I got with the gateway machine I have been using ( with Suse 7.2 ) until I got my new pc this weekend.

    I also noticed that the middle mouse button ( a clickable mouse wheel ) doesn't seem to work.

    I apologize for assuming that you knew more than you do. As a computer tech, I try to avoid that! What you have is a "PS/2" mouse, so named because that style and connector were introduced with the IBM PS/2 series of computers in 1988. The connector is known as a "mini-DIN" -- a PS/2 keyboard (the current standard) uses the same connector.

    The Universal Serial Bus (USB) is a newer standard for peripherals that allows up to 127 devices to be hooked to one set of ports. One of its advantages is that it's "hot-pluggable" -- that is, devices can be connected or removed with the power on. Newer systems have 2 to 6 USB ports on-board. USB devices include mouses, scanners, printers, cameras, MP3 players, etc. The USB connector is a small, flattened rectangle. It's common, especially with newer systems, to have a PS/2 keyboard and a USB mouse, hence the assumption.

    Now, on to your problem. I don't know why your mouse does not work properly. I would, in fact, try a Logitech USB mouse. All types of Linux seem to like them, and you can often find them at substantial discounts. For example, I have paid as little as $2.00 for a surplus 2-button Logitech USB mouse branded I-opener. Besides, it never hurts to have a spare.
