Comment 9 for bug 529230

I can also reproduce the bug behavior and have some more information:

The return key (both in the main typing area and on the numpad) is not the only one to cause the crash. I tried all keys on my (german standard usb) keyboard and found the following:

- both return keys cause the crash, as known
- key "2" causes the crash too
- key "r" switches the SCROLL LOCK LED on
- key "w" switches the SCROLL LOCK LED off
- SCROLL LOCK button does not switch any LEDs on or off. NUM LOCK or CAPS LOCK works though.
(- the "p" key caused the crash a week or two ago too. It doesn't anymore; I regularly install lucid updates)

This not only happens on the logon screen; if I turn on autologon if have the same behavior on the desktop.

Additionally, there is a strange video artifact showing. It start with just some blinking pixels in the top row to the right, every keypress adds a pixel. The last pixel in the right two rows keep on blinking though. I attached a (very real camera-taken) screenshot of the top of my screen to show the effect after some extensive typing.

Hope to help
