Hi,

I was doing nothing, watching the TV, which is a set on the wall behind the computer. Then I tried to look at something on the computer, and I typed "ctrl-alt-right". No response. The mouse responded, but not the keyboard. The lights in the keyboard (numeric block, upper case block), responded. But nothing on the screen.

I typed ctrl-alt-f1, this worked.

Immediately I saw in the screen this text:


cer@Telcontar:~>
Display all 6736 possibilities? (y or n)


I had to type no, and same question. I maintained the "n" key pressed, and I go a non stop flow of the question and the answer. Somehow I pressed something, and I got a non-stop of "^[^[^[^[^[^[^[^[^[^[^[^[..."
chars. If I typed something, it appeared interspersed.

(I'm not sure if I saw this stream in the xterm before going to text mode or not)

I unplugged the keyboard: non-stop flow of those chars! So it was not the keyboard hardware.


I sshed-in from a laptop: I run top, nothing obvious. In the end, I had to reboot the computer. I could see the flow of chars somewhere in the stop sequence.

Now things seem normal.

What could have been the problem?


There is nothing in the log, except the unplug event:
