Hi, I have a laptop with a mouse that was difficult in earlier kernels. The fix for me is to add: psmouse.proto=imps to the boot arguments. Note that the bug https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=120859 says that psmouse.proto=imps2 ^^^ didn't work for someone. It works for me without the '2'. -Cam
