Hello,
I have been seeing this for a while now (maybe two weeks or a bit more,
not sure when it started exactly):
After starting Emacs everything is good. But after a while, the mouse
wheel stops working. That is, mouse-4 and mouse-5, with and without
modifiers, are not recognized. In all buffers and windows, scroll-bar,
mode line, everywhere. C-h k shows nothing because no event is
registered.
When that happens the mouse wheel still works normally in other X
windows or the window manager or in a newly started Emacs session.
This is under X and Openbox.
TIA,
Michael.

mouse-4/mouse-5 or wheel-up/wheel-down?
Please be clear here, since they are handled separately under XInput 2.

You are right, the force of habit: When the events are considered they
are named "wheel-up/wheel-down" - I'm sorry.

Could you instrument this chunk of xterm.c:
/* See the comment on top of x_cache_xi_devices
for more details on how scroll wheel movement
is reported on XInput 2. */
delta = x_get_scroll_valuator_delta (dpyinfo, device,
i, *values, &val);
values++;
by adding:
printf ("%g\n", delta);
afterwards? Then, please see if any (and what) values are printed once
the mouse wheel stops working.

Short answer: nothing is printed.
Before the issue starts happening, I see -1 and +1 for each wheel
"click" and lots of 1.79769e+308 values when moving the mouse.
Once scrolling stopped working, mouse wheel turning leads to no output
any more (but the 1.79769e+308 values are still printed).
What I was also noticing: when turning the mouse wheel over the scroll
bar, there is a visual feedback: it looks like the scroll bar would lead
to a scroll (the bar moves), but scrolling is not happening, the buffer
text stands still. Also that is happening without output for DELTA.
Michael.

Hmm, thanks. Could you also add the following instrumentation to that
code, like such:
device = xi_device_from_id (dpyinfo, xev->deviceid);
if (!device)
{
fprintf (stderr, "device not found, %d\n", xev->deviceid);
goto XI_OTHER;
}
and see if that is ever printed when wheel movement stops working?

No, I got no output after the mouse wheel had stopped working.
But I have a new data point: there seems to be a relation with switching
to the X session of a different user. I sometimes have several X
sessions running a the same time. Some minutes ago the wheel had
stopped working. I switched to the X session at C-M-f2 and then back to
here (i.e. C-M-f1) and the mouse wheel started to work again.
I'm not saying that there is a connection between the failure and other
X sessions, however. AFAIR, when the mouse wheel stopped working
yesterday there was only one X session running. Maybe closing the
laptop (suspend to RAM) sometimes triggers this, but that's just
guessing. That switching X sessions healed the issue didn't seem
incidental, however. I had the feeling that I should try that, and I
had been using the mouse wheel as first action after switching the X
session back.
But I had been playing stuntrally with the joystick before I noticed the
mouse wheel stopped working. Maybe plugging in the Joystick is related
again....dunno if that guessing helps you, if not, I'm sorry for the
noise.
Michael.

I tested it a bit, and it's really that simple: plugging in or out the
Joystick reliably breaks the mouse wheel in Emacs, and C-M-f2 and back
reliably unbreaks it (this time there was only the tty2 Linux console,
no second X session).
HTH,
Michael.

Hmm, very odd. I will try to figure out why this is, thanks.

Indeed, thank you very much!
I quickly tested the recipe with the joystick, and it works as expected
now. No new problems as well (but I tested only one minute so far).
Thanks again,
Michael.

Any time, thanks for testing. I'm closing this bug.
