Fixing the Dreaded e02a Bug
If you have Ubuntu, you may have the dreaded e02a bug where, when you do tail -f /var/log/messages and begin typing, eventually an error will repeatedly pop out that complains about setkeycodes and a keystroke named e02a.
Unfortunately many people have put the fix on the Ubuntu site, but then some dope keeps moving it, as if being malicious. Therefore, I'm going to tell you the fix here. I've done it and it works.
