I'm trying to use a Apple Magic Mouse on a ordinary PC with Ubuntu Linux 10.04. Out of the box the mouse "worked" in Lucid. Paring, moving the cursor over the screen and right/left clicks worked. After I installed multitouch-kernel-source_1.2. and a reboot I was able to scroll and do middle clicks. So more or less it worked very good. Today (i can't remember that i changed a thing) the cursor is stuck at the top left corner of the screen, even when I move the mouse. When i touch the surface of the mouse I can move the cursor. It looks like the surface of the mouse controls the position of the cursor on my screen. I installed the kernel module inside Ubuntu Lucid Lynx 10.04 and the PPA of Chase Douglas [1]. $lsmod | grep magic hid 81789 4 hid_magicmouse,hidp,hid_apple,usbhid $ dpkg -l *multitouch* | grep ii ii multitouch-kernel-source 1.2 Experimental multitouch device driver source $ uname -ar Linux stein 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:27:30 UTC 2010 i686 GNU/Linux Other people [2] report similar issues. Deleting the connection between my system and the mouse and re-pair it doesn't help.
