i just meant that i realized when the problem starts.
it's when i have a certain number of programs running. for example, if i have firefox, totem, and jdownloader open at the same time, my keyboard stops working. i have to close one of those programs for my keyboard to work again. i don't know how to fix it yet. i just know how the problem starts..
I have a similar problem. Still trying to figure out what makes it happen.
In my case the back space key and the delete key both stop working.
The delete-key on the keypad keeps working.
Testing the non-responsive keys with xev shows indeed no response at all from both keys.
I was under the assumption that the keys stopped working while entering text in a search field in Firefox. I have installed Chromium which shows the same problem.
Following the next post - control-center/keyboard/check if there is a tick before typing break - the keyboard started functioning normal. While typing this message it stopped working again and - after selecting a portion of text and typing on - it started reacting again.
In short - it is still very uncertaing what happens and what triggers it.
EDIT- the trigger is still not clear but the solution is now!! It stops backspacing? cursor to the left, select the text, overtype and VOILA! Backspace works again.
