Mighty Mouse: reverse horizontal scrolling workaround on Ubuntu Linux 9.04

0 Comments Published September 1st, 2009 in Apple, Linux Tags: .

The reverse horizontal scrolling problem is due to some old compatibility quirk on Apple's mouse that was using reversed scroll, and the problematic code is still there in newer kernels. See the bug: 291408.

If your mighty mouse scroll ball is horizontally reversed, it can be solved in this way:

- open file /var/lib/bluetooth/xx:xx:xx:xx:xx:xx/did
- change yy:yy:yy:yy::yy:yy 0002 05AC 030C 0200
       into yy:yy:yy:yy::yy:yy FFFF 0000 0000 0000
- reboot

When/If the kernel will be patched to correctly address horizontal scrolling, you can restore back the original values, or you may choose to keep a backup for that file.
