Hi Radule,

Funny you should post this... I just experienced the same problem for a
*second* time. Before you go crazy chasing down and trying different
modules/drivers/settings, etc., I highly recommend you just install a
new or borrowed (known working) mouse.

Background: The first time I experienced this problem was last year --
immediately after one of those "supplementary" KDE upgrades. I tried to
resolve it unsuccessfully for a weekend and, eventually, just formatted
and reinstalled. I ran a 'stock' system plus YOU updates until a few
months later, when the mouse just suddenly "died." It couldn't be seen
by either SuSE or my fall-back Win98SE. I even replaced the cable using
a cannibalized one from a known good mouse. No joy... obviously a
sensor or some supporting circuitry had failed. The problem was solved
by purchasing a new mouse.

The relevant point: I treated the first incident as a KDE/Linux issue
and the second as a simple hardware failure. I didn't connect the dots
because there were too few of them.

Yesterday, I backed up my perfectly stable but highly customized SuSE
9.0 installation and installed 9.2. Within an hour of starting to test
drive the new version, my mouse cursor started 'ducking under' (still
there but invisible) and activating whatever link it happened to find
itself hovering over. When it decided to reappear, it was someplace
unexpected and random on the screen. It ignored about half of my
attempts to guide it when it did decide to become visible. And yes, the
behavior was random and intermittent.

I *almost* started looking at drivers/modules/settings again, but
instead -- based on hindsight -- I opened the mouse and replaced the
cable. It worked like a charm. I'd bet money now that a failing cable
is what actually killed the circuitry in my previous mouse.

Of course, YMMV, but maybe this might be useful.

Good luck!

- Carl
