last time I let my Ubuntu 11.04 to upgrade all its packages, I think a new kernel was also downloaded. Since then keyboard stopped working so that I can press Enter button on the login screen, but after I get the desktop ready I cannot type. The kernel version is 2.6.38 but if I boot with 2.6.35 nothing changes. I can start Ubuntu in recovery mode, keyboard is working there, but I don't know what to do there.
When I looked around the settings on a certain menu point (Input settings or kind of) I got an error message that IBus daemon is not started. I was asked if I'd like to start it, but after starting nothing got better.
Do you have any idea how could I get my keyboard working again?
UPDATE: after a recovery mode package update keyboard is working, but I have to press each button for about 1 second to see the letter on the screen, fast typing is impossible. Key combinations, such as Alt-Shift-T are not working at all.
