Public bug reported:
Every 3 days or so, my Microsoft Natural Keyboard 4000 starts messing up
the keypad keys. In a GOOD state, pressing the End key on the keypad
would generate the following events:
KeyPress event, serial 35, synthetic NO, window 0x3a00001,
root 0x237, subw 0x3a00002, time 5911446, (53,48), root:(727,74),
state 0x0, keycode 87 (keysym 0xff9c, KP_End), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 35, synthetic NO, window 0x3a00001,
root 0x237, subw 0x3a00002, time 5911542, (53,48), root:(727,74),
state 0x0, keycode 87 (keysym 0xff9c, KP_End), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
Pressing Ins and Del keys work similarly.
In a BAD state however, the situation is as follows:
* End key - KP_End WITH pointer movement
MotionNotify event, serial 35, synthetic NO, window 0x3a00001,
root 0x237, subw 0x3a00002, time 5799275, (38,33), root:(712,59),
state 0x0, is_hint 0, same_screen YES
KeyRelease event, serial 35, synthetic NO, window 0x3a00001,
root 0x237, subw 0x3a00002, time 5799395, (38,33), root:(712,59),
state 0x0, keycode 87 (keysym 0xff9c, KP_End), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
Note, that there is no KeyPress event, which makes the ley useless for
the apps that expect it.
* Del key - completely ignored
* Ins key - strange KeymapNotify event.
The problem is cured by unplugging the keyboard and then plugging it
back.
The system is AMD Opteron based Ubuntu 9.04 64 bit.
