xorg 7.5, usb keyboard freezes gui for a short time

[hedgehog]

when I attach an usb keyboard, gui freezes for second or so every time I switch language or hit num lock/caps lock buttons. mostly annoying in games or while watching movies in background. i have tried Defeder keyboard (can't remember exact model) and Flexible Full Sized. Everything smooth with ps/2 keyboard.

FreeBSD 8.0-p3
Xorg 7.5
KDE 4.4.5

hald and dbus are enabled

It's not clear what you mean by "switch language". How are you doing that?

Maybe something to do with kbdmux (4) (http://man.freebsd.org/kbdmux/4).

Of course, our old friend AllowEmptyInput Off in xorg.conf is always possible, but it doesn't sound much like that type of problem. Worth checking, anyway.

sorry, i meant switching keyboard layout (from russian to english and vice versa, alt+shift hotkey with my settings)

I don't have this option in xorg.conf, but I'll give it a try

Sorry, I was unclear. You should not set AllowEmptyInput in xorg.conf. Leave it out.

Some USB keyboards are composite devices, both a keyboard and mouse in one. If yours is that way, setting moused_enable="YES" in /etc/rc.conf and restarting may help. At least it makes switching between X and console faster.
