I have just upgraded a machine from 4.7 to 4.8 and I have a problem with
the mouse's scroll wheel in X Windows. Scrolling down is fine but
scrolling up scrolls down a page at a time - it wont scroll up at all.
This was working fine since I put 4.1 on the machine a few years ago.
I have tried various apps under various window managers and all have
the same problem. I have tried different mouse protocols Just In
Case(TM) and they of course gave the other expected problems and didn't
solve scrolling. I removed my xorg.conf so as to use bog standard
defaults - same problem. I generated a new xorg.conf and compared with
my current and there were no differences. Well only for video card -
updated for new options and still the same problem.
An hour on Google doesn't turn up anything obvious apart from mouse
configurations which match/are close to my settings. FTR I am using a
self powered 2-port KVM but have been using this as long as the hardware
without any problems - the windows box on the same KVM is having no
problems with the scroll wheel.
So wumps around the noggin with a klew stik would be appreciated.
Attached are my dmesg, xorg.cong, and Xorg.0.log ...

Its a hardware issue. The KVM mouse lead has become a loose fit over
time (it gets shared with another box occasionally) and must be having a
problem with some of the pins. Plugging the mouse in directly is a snug
fit and no scrolling problems. First hardware purchase of the new year
will be a new KVM.
