Ouch...

I thought my vibration was dead, because I enabled it in profiles, and it still did not work.

So, I sent dbus command. MCE says: do not know anything about vibrator.

And then, I recall... How, long ago, I disabled vibrator module in /etc/mce/mce.ini... between keypad and led...

Hooray. Hopefully, vibrator will work soon, after mce restarts.

Best wishes.
