In the middle of doing something (or not doing anything) in the KDE gui the screen changes to a login prompt on tty1 - wasn't the x server display supposed to be on tty1? Pressing Ctrl-Alt-F2 brings me back to the running KDE desktop. Wasn't this supposed to be the other way round?
Anyhow, this changing of the ttys happens continually (every 20-30 seconds) which makes it very hard to do anything. You read something in your browser - black screen with login prompt. You press Ctrl+Alt+F2 and commence reading - black screen with login prompt. You press Ctrl+Alt+F2 again and commence reading - black screen again. You shutdown and go fishing. Or write a post such as this one.
