I just found that keyboard is not working under user account.
If i log in under root - keyboard works fine. 3 hours before everything was OK. What can I do now?
Sorry, if this question is simple (I understand, that I mostly need to try to erase configuration file for this user, but I don`t know where).
Please NEVER log in as root. It can lead to many other problems, what you’ll never fix and usually leads to a complete reinstalling of your system.
If the login screen comes up from the System menu select the Console login option. Here login as root and start sax2 to configure your keyboard by typing:
Thanks for answer and for caution about root login.
I fix the problem another way: there was “slow keys” option enabled. I was not enabling it, so may be there is a shortcut for enabling it. Time delay was 1 second!
