I have a lenovo thinkpad Z470 running mint 12. For some reason, it's getting spurious key events. That is, when I'm not pressing any keys or moving the mouse at all, these two events show up every 28 seconds in xev:
Code: Select all
KeyPress event, serial 33, synthetic NO, window 0x1a00001,
root 0xae, subw 0x0, time 1079394, (729,130), root:(730,177),
state 0x0, keycode 248 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 33, synthetic NO, window 0x1a00001,
root 0xae, subw 0x0, time 1079394, (729,130), root:(730,177),
state 0x0, keycode 248 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
I've tracked it down this far, but I don't know what to do from here. Anyone have any ideas about finding their source?
What's keycode 248 used for? I thought it was outside the range of keycodes.
