Tested by ajacoutot@, jasper@, krw@, shadchin@. I believe that the bugs spotted by krw@ are fixed in an upcoming inputproto update.

The XSetDeviceValuators request sets the current values of the

valuators of an input device\&. The valuators in the range
|
|
first_valuator to (first_valuator + num_valuators) are set to
|
|
the specified values\&. Valuators are numbered beginning with 0\&.
|
|
Not all input devices support initialization of valuator
|
|
values\&. If this request is made to a device that does not
|
|
support valuators initialization, a BadMatch error will occur\&.

This error may occur if an XSetDeviceValuators request
