The thing i notice is that in old kernel Xorg log file is (II) config/hal: Adding input device ImPS/2 Synaptics TouchPad (II) XINPUT: Adding extended input device "ImPS/2 Synaptics TouchPad" (type: MOUSE) Where in the new kernel Xorg file contains (II) config/hal: Adding input device SynPS/2 Synaptics TouchPad (II) XINPUT: Adding extended input device "SynPS/2 Synaptics TouchPad" (type: TOUCHPAD) so does it make a difference? _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
