Keyboard has stopped working

Asked by Tyler Folsom

Ubuntu 11.04 (kernel 2.6.38-10 generic) has been running fine on my desktop. I have been keeping current with updates. Computer is Pentium 4 with USB mouse and pre-USB keyboard connection. Yesterday the keyboard stopped working. I have not been able to boot, since I cannot enter a password. The mouse works. Under Ubuntu, pressing Num Lock will not light the corresponding keyboard LED. The only key that Ubuntu responds to is "Power Off".
This is a dual-boot computer. When I run Windows XP, the keyboard is completely functional. When I run Ubuntu, a USB keyboard does not work. The suspend and recover trick from #90549 does not work. When I try, I lose the mouse.
I can start Ubuntu in recovery mode and the keyboard works. I can resume the normal boot sequence and the computer boots to terminal mode with the keyboard working. I know little Linux at the command line level. What file has been corrupted?

Does not work. When I run 2.6.38-8 I also have no keyboard. Going back to previous versions leaves me in text mode, which is what I can get in recover mode from 2.6.38-10.

The problem was that Universal Access had gotten set for sticky keys. This computer was out of service for four weeks until I discovered that clicking on the obscure glyph on the lower right bar would bring up a menu that let me put things back to normal. The bug can be restated as "Setting sticky keys prevents being able to log in".
