Comment 11 for bug 194343

Same bug, but under metacity.

10.4, 2.6.32-24-generic, GNOME 2.30.2

Pressing a modifier (ctrl or shift) key with another key is needed for the problem to appear.

Once triggered, the key repeats and cannot be stopped, bar a logout or reboot.

However, haven't found a reliable way to reproduce the problem.

Some suggest it can be triggered when launching firefox while doing some editing, particularly in the first 5 minutes of power on.

The problem is not dependent on compiz.
