This is just weird.
One user account completely ignores all keyboard input. No other account demonstrates this bizarre behavior. The faulty account has had occasional keyboard difficulty but it has always been related to the Virtual Machines (VirtualBox); the hosting account always functioned correctly.
Then the ban on keyboard input. Poof! “Keyboard? What keyboard? I don’t see no stinking keyboard!”
It is not the physical keyboard. Three different hardware exhibit the same fault. It is not the motherboard; two mb’s show the same fault. It is only that one account. And I even took the Windows route of re-installing the OS (what a waste of time that was).
If something changed, I am not aware of it (although something must have).
Any ideas where to look? (Remember: I cannot type anything in that account.)
If it is that you have an installation that has more than one user account, one of which has this issue, but the others are fine.
We can assume from this that the problem must be in the user settings and be from the system settings. Therefore, you would do well to look at those settings.
But is it that you can Never use the keyboard or just sometimes?
At the login screen there should be a Menu at the bottom that offers a Console Login. Go to it and login with your username and password. Hopefully you will be able to use the keyboard to do that and beyond.
I’m about to give you a command to rename a folder, it will start a new kde4 settings/config folder, you can get some settings you may need from the old re-named folder if necessary. Assuming you are logged in under this troublesome username
So here is what to do now - type at the prompt:
mv .kde4 .kde4-old
