[ubuntu-x] strange mouse behavior on OGL games after upgrade to Hardy

[Rob Hughes]

The mouse only does this in opengl games, just as ET or UT. Immediately
upon starting the game, the mouse goes into the lower-right corner. I
can briefly move the cursor from the corner, but as soon as I stop
moving the mouse, the cursor jumps back to the corner. Never happened
before the upgrade to Hardy. Anyone have any ideas? Or at least some
tips on debugging this?
