Down arrow key doesn't do anything after upgrade

[Matthew Paul Thomas]

MacBook (2007 model)

1. In Ubuntu 8.04, set the keyboard layout to "USA Macintosh".
2. Upgrade to Intrepid.
3. Restart.
4. Try to use the Down arrow key.

What should happen: The insertion point moves down, the page scrolls down, etc.
What happens: Nothing.

The Down key continues to do nothing even after changing keyboard layouts in the Keyboard Preferences.

Similar to the fixed bug 255008.

Fn+Down still triggers Page Down as expected, and Fn+Ctrl+Down switches to the next tab in tabbed windows. It's just Down by itself that doesn't work.

What more information would help?

In Ubuntu 8.04, I had added this entry in .xmodmap made Command click simulate right-clicking:
    keycode 116 = Pointer_Button3

In an 8.04 update a month or two ago, this line stopped working and I had forgotten about it.

In Intrepid, keycode 116 has apparently been changed to represent the Down key rather than Command click. This is why, with that line in .xmodmap, pressing the Down key does not work.

Solution: remove the line from .xmodmap.

Underlying problem: Ubuntu expects people to be able to right-click but does not set up a working key combo for that purpose by default (bug 122962).
