(Moving to linux-input.) I happen to have both a PS/2 and USB keyboard plugged, in, but was noticing that the caps lock key seemed inverted. When the LED was off, I got all caps (unless I used shift), while when it was on I got normal lower-case letters. This quite confused me, until I looked over and saw that someone had hit caps lock on the PS/2. Experimenting, it seems that each keyboard has its own caps lock LED state, and the XOR of the two controls the case of the letters. The corresponding shift keys have a shared logical state which depends on who last had a transition. Holding down left-shift on one can be cancelled by pressing and releasing left-shift on the other. (But left & right shift are tracked separately.) It would make more sense if each keyboard's caps lock LED controlled the effect on its keys. Either give each keyboard a completely separate caps lock state, or toggle both LEDs when either caps lock is pressed. Perhaps the answer is "It's too much work to fix; stop doing something so stupid", but I thought I'd at least mention it. (Er... it appears that my XOR description was incomplete. I now have the keyboard system in a state where *one* caps lock LED has to be on to get normal lower-case letters. I was playing with down1/down2/up1/up2 combinations, but I'm not quite sure what happened...) -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
