OFFICE MEMO the mouse that snored Date:9/20/95
I think I have a bug (else hardware problem), so I am forwarding this to the
bugs distribution rather than questions where I first raised it.
I am accused to have said:

Some additional information: The port is recognized at boot. The XF86Config
shows /dev/psm0 as pointer device and PS/2 as protocol. This driver is S3 and
the Mouse is a Logitech product.
After first experience the problem I restored root from backup (using dd).
Then the mouse worked the first time, but not subsequent times. Till I
restored the root again, in which case the mouse worked the first but not
subsequent times.
The problem occured with both xdm and startx. Logs did not report any mouse
errors.
I reconfigured startx with warpto specified in a function key. This allowed
me to get off the root menu where I had been stuck (especially nasty with xdm)
and log out of X cleanly. I started experimenting and found that sometimes
when I startx it works and sometimes not- even when I haven't tampered with
the config files in between. I think I have a race condition. Once
operational the mouse works fine every time throughout the X session.
This is circumstantial, but the frequency of the problem seems to vary
depending how I have .twmrc configured. Lately its been working right pretty
consistently. Anyhow I can circumvent by trying startx again. I'm reporting
this to share the circumvention and information that might aid in debugging
down the road.
Two other users have reported a similar problem with PS/2 mouse (at least one
of them with S3) so this may well be related and I've copied them. However,
in my case, once dead always dead, at least until the next time I startx...
Cheers!
