Re: Problems with (ws)mice, KVM switches.

I've had a similar problem with OpenBSD 3.2 & 3.1 and a two-machine "El
Cheapo" KVM... On some apps, like konqueror-embedded, the mouse goes
haywire, and I just switch to one of the virtual terminals and back to X and
the problem goes away... I only get this problem using konq-e, but not on
graphical Links+, xterm, xman, xcalc, or xlock...

Subject: Problems with (ws)mice, KVM switches.


I seem to be having trouble with mice.  The first thing that happened was
they put a KVM switch in at work (Windows and OpenBSD machines) and the
mouse (Microsoft PS/2 Intellimouse) freaked out on the OpenBSD machine. The
cursor would just go crazy the instant you touched the mouse.

So I searched the mail archives and saw that someone else had the same
problem and it was caused by Windows doing something to the mouse (baud
rate, mode, ?) that made it freak out on OpenBSD.  I tried just plugging
another mouse into the OpenBSD machine, but it wouldn't work at all.

So I gave up at the time and didn't use X Windows.  But since I had to
reboot it yesterday after I installed the patches and rebuilt the kernel. I
put the other mouse on it and rebooted.  Then the mouse worked.  But if I
try to startx from a different virtual terminal and virtual terminal 0 is
logged out, I get "Cannot open /dev/wsmouse Permission Denied."

Now I have put a KVM switch on my machine at home and the mouse goes crazy
on it.  I haven't had a mouse connected to it for quite a while so I can't
say for sure if it would have worked before the KVM switch.  But I don't
have any Windows machines at home, so I'm not sure what would be messing it
up?  Linux?

Is there anyway to get OpenBSD to re-initialize the mouse after it's running
or do you have to do a reboot?

Thanks
