Comment 15 for bug 138094

I have the same problem on a Thinkpad R52. Strangely I had the same problem with Kubuntu 6.06, but not with Kubuntu 7.04. At first I thought it had something to do with video drivers (I used opensource radeon driver with 6.06 and fglrx with 7.04), but it doesn't make any difference with Kubuntu 7.10. I can still use the keyboard, if I press each key for about 2-3 seconds. My only solution for now is to restart X with Ctrl + Alt + Backspace.
