XInput device properties ; keymaps service & console switch

[Sebastian Glita]

Hi,

2.

Sorry, it was only F1..F12+ALT and windows key, not just F1..F12.

I inserted xev output below,

I pressed/released Ctrl a couple of times; then pressed/released the windows key 
twice: each time I got a VT switch, I used ALT+F7 to switch from console to Xorg 
back again. Same would happen with ALT+F1..12 or menu key instead of Super_L. 

It seems Ctrl key is not stuck.

Thanks,
s.

VT switching disables all devices and re-enables them when coming back. It's
been like this for ages and I'm not really inclined to change this
behaviour at this point.

Generally, any use of xinput is a once-off effect only and the setting set
by xinput is not guaranteed to be maintained and/or monitored for changes.

what does xev say about key presses? is the ctrl key stuck?
