Comment 117 for bug 261721

I'm experiencing the same problem on a Samsung r60+ laptop, on both Jaunty and Karmic alpha2.
The problem is the same as described in this duplicate: <a href="https://bugs.launchpad.net/bugs/282963">bug 282963</a>. The keyboard becomes unresponsive as well as most of the applets in the gnome-panel. Only way to get back to normal is to ctrl-alt-backspace (which I have activated back).
