Synaptics Touchpad failure solution under Ubuntu12.04

Under Ubuntu12.04, the Touchpad (Synaptics Touchpad) failed to solve the problem. I don't know what to install or what to upgrade. the Touchpad suddenly failed. After some google/baidu operations, I finally found a solution, it turns out that the imps mouse module needs to be loaded, vincent @ 3830TG :~ $ Sudo-I [sudo] password for vincent: root @ 3830TG :~ # Modprobe-r psmouseroot @ 3830TG :~ # Modprobe psmouse proto = imps, but after restarting the computer, the touchpad is still unavailable and the module needs to be re-loaded. Therefore, you need to add an automatic file loading command, root @ 3830TG :~ # Echo options psmouse proto = imps>/etc/modprobe. d/options
