I got it while running ex_mouse_events. I tried it with and without
touch input installed and got the same error. I don't quite know how to
pinpoint the line (I'd be grateful if you explained to me how to debug
this, as there are a few others X errors that I had no idea how to
localize where they occur).
Here's the output of xinput --version
xinput version 1.6.1
XI version on server: 2.3
Thanks,

That error can occur for several reasons if you do something the xinput
API doesn't like.
I encountered it myself while refactoring, but I resolved it for my
particular case.
On what line of code did the error occur?
Was it with any specific allegro example?
Was it just with mouse input that it failed or was touch input installed
or both?

So I tried this on my Ubuntu and got this error:
X Error of failed request: BadValue (integer parameter out of range
for operation)
Major opcode of failed request: 132 (XInputExtension)
Minor opcode of failed request: 46 ()
Value in failed request: 0xd
Serial number of failed request: 228
Current serial number in output stream: 229
Do you know what that means?

Attached is a patch that enables Xinput2 API for processing
mouse-movement.
No new functionality is implemented.
Notes:
-I refactored/moved the x11 touch input setup stuff since it
also gets
used for the mouse
-touchpad events were implemented in Xinput 2.1, but touchscreen
events
are in ver 2.2
I simply made 2.2 the minimum requirement. I don't think it's
worth it
to test for both versions
and it seems to be what other projects (eg: GTK) are doing.
Important:
Xorg apparently does not allow using both the legacy API and
Xinput2 for
the same event class.
So enabling listening for XI_Motion events causes the
MotionNotify events to stop.
Hence, this patch _only_ grabs the mouse-movement events in
Xinput2 so
that allegro has access to touchpad events we can add later in
the future.
All other inputs + window + mouse events are all still being
handled by
the legacy API.
Testing:
- allegro5 builds with and without xinput2 support
- mouse example programs and ALLEGRO_MOUSE_EVENT members all
work for
legacy and XInput2 versions.
- pointer and mouse-wheel acceleration work for mouse and touchpad
- hot-plugging USB mouse works and simultaneous use with
touchpad works
Everything behaved as expected for me.
Please review and consider for addition.
Thanks,
Pho75
