I was searching for the program schedule for Dish networks new (cheapest) Russian ala cart programming: ТВ-1000 Русское кино (TV1000 RUSSIAN KINO). Searching in English did not bear fruit so I switched my keyboard layout to Russian and searched. I found what I was looking for! A nice program schedule which also had movie descriptions (in Russian). I then got busy with other things and forgot about my PC.
When I came back to my desk, I was unable to unlock my keyboard. Again and again I tried, carefully typing my password and making note of the caps lock key indicator. Caps lock is off and I am typing it correctly: "I've been hacked!!" That always pops into my mind when this sort of thing happens. "No, no." I tell myself. "Don't jump to conclusions. That has never turned out to be the case in any of these situations." Then I notice: the keyboard layout is set to Russian! I'll NEVER be able to enter my password with a Russian keyboard layout. Что делать?!
I Googled for a possible hot key to toggle the keyboard layout (you can do this at the desktop - but in the screen lock position?) No luck. Then it occurred to be to use on of the pseudo tty terminals (I use Ubuntu Linux). Yup! Got in and killed off the screen saver and then toggled off the Russian keyboard layout. Whew!
